Introduction

Open-cast mining is one of the most demanding industrial environments on Earth. In Indonesia, where vast coal, nickel, and gold reserves are spread across Kalimantan, Sumatra, and Papua, operations face unique and extreme conditions. High temperatures, heavy rainfall, intense ultraviolet radiation, high humidity, and corrosive soil create a perfect storm for equipment failure. But the greatest challenge comes from the machinery itself: massive excavators, dump trucks, stackers, reclaimers, and mobile crushers that move continuously, day and night, 365 days a year. These machines rely on medium voltage (MV) power cables that are not just installed and forgotten—they are wound, unwound, bent, twisted, stretched, and dragged thousands of times over their service life.

For decades, mine operators faced a costly and frustrating reality: standard industrial cables failed quickly. They would develop cracks, break conductors, suffer insulation breakdown, or lose signal capability within just three to six months. Every failure meant stopping production, which in a large Indonesian mine can cost between $50,000 and $200,000 per day in lost output. Maintenance crews spent more time replacing cables than maintaining equipment, and reliability remained low.

This is where PROTOLON(M)-R LWL (N)TSCGEWOEU changes everything. It is not merely an improved version of a standard cable. It is a complete engineering system—a synthesis of advanced materials science, precision electrical design, and optimized mechanical structure—purpose-built to solve four fundamental problems that have plagued mining operations for generations: continuous movement, repeated reeling cycles, harsh environmental exposure, and the need for integrated power and data transmission.

This cable redefines what a reeling cable can be. Designed to the strict DIN VDE 0250-813 standard, it has become the global benchmark, and today it is the trusted choice for major mining projects across Indonesia and Southeast Asia. In this article, we will explore exactly how it is built, why it works where others fail, and how Feichun Cables delivers an identical, high-performance equivalent that offers significant advantages in cost and delivery speed for regional projects.

Technical Specifications and Compliance

To understand the capability of PROTOLON(M)-R LWL (N)TSCGEWOEU, we must first look at its precise technical profile, derived directly from the official product documentation. Every parameter is engineered to perform under extreme stress.

Basic Identification and Standards

Full Type Designation: PROTOLON(M)-R LWL (N)TSCGEWOEU
Description: Medium Voltage Reeling Cable with Integrated Fiber Optics
Core Standard: DIN VDE 0250-813 – the definitive German standard for flexible cables for reeling and trailing applications, recognized globally as the most rigorous specification for this product category.
Certifications: MSHA P-189-4 (approved for use in mines), GOST K and GOST B (Eurasian Conformity), and compliance with EN 60332-1-2 / IEC 60332-1-2 for flame retardancy.
Design Philosophy: Every dimension and material choice is validated through type tests including reverse bending, torsional stress, and roller bending (Type C) – tests that simulate years of mining operation in a laboratory setting.

Voltage Classes

The cable covers the full range of medium voltage requirements found in mining and heavy industry:

3.6/6 kV
6/10 kV
8.7/15 kV
12/20 kV
14/25 kV
18/30 kV
20/35 kV

For each voltage class, the maximum permissible operating voltage is higher than the nominal rating, ensuring safety during system fluctuations. For example, the 6/10 kV version operates safely up to 6.9/12 kV AC or 9/18 kV DC, and withstands a 17 kV AC test voltage during manufacturing.

Conductor and Construction Sizes

Available in a robust range suitable for powering machinery from small crushers to the largest electric shovels:

Power Cores: 3-core design, cross-sections from 3×25 mm² up to 3×300 mm²
Protective Earth: Split-conductor design 2×25/2 mm² up to 2×150/2 mm² – this unique split structure improves flexibility while maintaining full fault-current capacity
Fiber Optic Unit: Configurable with 4 to 24 optical fibers, available in three types:
- G50/125 µm: Multimode, high bandwidth
- G62.5/125 µm: Multimode, optimized for legacy systems
- E9/125 µm: Single-mode, long-distance, low attenuation

Current Carrying Capacity: From 131 A (25 mm²) to 620 A (300 mm²) at 30°C ambient temperature
Short Circuit Rating: From 3.58 kA to 42.9 kA – ensures safety during fault conditions

All these figures are not just theoretical; they are verified by the rigorous testing required by DIN VDE 0250-813, ensuring consistency and reliability across every meter of cable produced.

Structure and Material Science: Layer-by-Layer Engineering

The true genius of PROTOLON(M)-R LWL (N)TSCGEWOEU lies in its construction. It is built as a multi-layered system where every component has a specific function, and the interaction between materials is scientifically optimized. We will examine each layer from the center outwards, explaining the engineering principles and material science that make it work.

Overview: A System, Not Just a Cable

Most standard cables are designed for static installation. They are built to carry current, not to move. PROTOLON(M)-R is designed from the ground up for dynamic service. The design philosophy balances three opposing forces: flexibility vs. strength, insulation vs. heat dissipation, and protection vs. weight. It achieves this balance through eight distinct layers, each selected for specific properties.

Conductor – The Science of Flexibility and Strength

Construction: Electrolytic copper, un-tinned, Class FS (Extra-Fine Stranding).

Unlike standard cables which use Class 2 or Class 5 stranding, PROTOLON uses the finest possible copper wires. Each single wire has a diameter of less than 0.2 mm, and thousands of these wires are stranded together in multiple layers with optimized pitch lengths.

Why this design?

Mechanical Principle: Metal Fatigue and Stress Distribution: When a cable bends, the outer surface stretches and the inner surface compresses. In a cable with thick strands, the stress is concentrated on just a few wires, leading to rapid fatigue and breakage after a few hundred bends. With ultra-fine strands, the stress is distributed across thousands of individual wires. Each wire moves slightly relative to its neighbor, effectively "absorbing" the bending energy. This increases the fatigue life by a factor of 10 to 15 times compared to standard designs.
Electrical Principle: High-purity electrolytic copper ensures low resistance and efficient power transfer, while the compacted stranding reduces overall diameter and improves roundness.

Semiconducting Layers – Controlling the Electric Field

Materials: Special conductive rubber compounds designated 3GMx.

Applied immediately over the conductor and directly under the insulation, these layers are invisible but vital.

Engineering Purpose:

Electric Field Homogenization: In medium voltage cables, the electrical field is strongest at the sharpest points. Without semiconducting layers, high field concentrations would cause "partial discharge" – tiny electrical sparks that eat away at insulation over time, eventually causing failure.
Scientific Principle: By making the conductor surface perfectly smooth and ensuring the interface between insulation and conductor is free of air gaps, the electrical field is distributed evenly and radially. This is the fundamental reason this cable operates reliably at high voltages for decades, rather than just years.

Insulation – PROTOLON 3G13 EPR: The Heart of the Cable

Material: PROTOLON 3G13 – a proprietary, specially formulated Ethylene Propylene Rubber (EPR) compound. This is not generic EPR used in standard cables.

Why EPR and why this specific compound?

Electrical Science: EPR has a very low dielectric constant (~2.5) and extremely low dielectric loss factor (<0.001). This means it does not heat up significantly under high voltage stress, even at 90°C. It has a dielectric strength exceeding 22 kV/mm, providing a massive safety margin.
Mechanical Science: Unlike cross-linked polyethylene (XLPE), which is rigid and cracks when bent repeatedly, EPR is an elastomer. It has an elongation at break of over 300%. It stretches, compresses, and recovers its shape perfectly thousands of times. It is designed to bend.
Material Chemistry: The 3G13 formulation is highly cross-linked. This molecular structure gives it exceptional resistance to heat aging, ozone attack, and UV radiation. In chemical terms, the polymer chains are bonded tightly together, preventing oxygen or ozone from breaking them down – the primary cause of hardening and cracking in tropical environments.

Difference: PROTOLON(M)-R vs. PROTOLON(M)-R LWL (Fiber Optic Version)

This is a critical distinction. The non-fiber version is a standard power cable. The LWL / FO version integrates the optical fiber unit within the structural gaps of the cable, specifically in the outer interstices between the cores.

In FO Version: The fiber unit is placed here to ensure it is never subjected to mechanical load. The power cores and reinforcement carry all tension and torsion; the fiber unit floats freely.
In Non-FO Version: These gaps are simply filled with rubber or textile.
Result: The FO version provides identical mechanical and electrical performance plus high-speed data, without compromising strength or durability.

Optical Fiber Unit – Power and Data in One

Construction:

Fiber Types:
- G50/125 µm: Attenuation <2.8 dB/km @850 nm, <0.8 dB/km @1310 nm; Bandwidth >400/1200 MHz·km
- G62.5/125 µm: Attenuation <3.3 dB/km @850 nm, <0.9 dB/km @1310 nm; Bandwidth >400/600 MHz·km
- E9/125 µm (Single Mode): Attenuation <0.4 dB/km @1310 nm, <0.3 dB/km @1550 nm; Chromatic dispersion <3.5 ps/nm·km
Protection: Fibers are coated, placed in ETFE (Ethylene Tetrafluoroethylene) tubes (material code 7YI1), filled with water-blocking compound, and grouped around a central strength member.

Engineering Logic:

Mechanical Decoupling: The fiber unit is structurally independent. It does not touch the outer sheath or reinforcement. It cannot be crushed or stretched.
Data Integrity: Unlike copper signal cables, fiber optics are immune to electromagnetic interference (EMI). In a mine where high currents create massive magnetic fields, copper signals get distorted. Fiber signals remain perfect.
Value: Enables real-time monitoring of equipment health, temperature, vibration, and fault location. This transforms a cable from a simple power carrier into a part of a smart mining system.

Split Protective Earth Conductors

Design: 2×25/2 mm² … 2×150/2 mm²

Instead of one large earth wire, two smaller ones are used.

Why? A large solid conductor is stiff and resists bending. Two smaller conductors are flexible like rope, yet together they carry the same fault current. This detail alone improves cable life significantly.

Inner Sheath – EPR 5GM3

Material: Special EPR compound 5GM3

Function: Acts as a cushion, separating the core assembly from the reinforcement layer. It provides a smooth surface for the braid to bond to and prevents internal abrasion during bending. It is chemically matched to the insulation and outer sheath to ensure perfect adhesion and no delamination.

Reinforcement – Polyester Braid: The Secret of Durability

Construction: High-tenacity polyester threads, tightly braided, and vulcanized into a single composite structure between the inner and outer sheaths.

This is arguably the most important layer for mining applications.

Science of Composite Mechanics:

Standard Cable: Rubber is flexible but stretches easily. If you pull it, it elongates permanently, damaging the insulation.
PROTOLON Design: Rubber + Polyester. Polyester has a tensile strength of over 800 N/mm² but very low elongation (<15%).
Effect: The braid takes the load. It prevents the cable from stretching or shrinking. It balances torsional forces so the cable does not twist or jam on the reel.
Analogy: It works exactly like reinforced concrete – concrete (rubber) handles compression, steel (polyester) handles tension. Together, they create a material that is both flexible and rigid where it counts.

Outer Sheath – Chloroprene (CR) / Special Elastomer

Material: High-grade synthetic elastomer, primarily Chloroprene Rubber (CR), color red.

This is the cable’s armor against the world.

Material Science & Environmental Resistance:

Chemical Resistance: CR contains chlorine atoms in its molecular structure. This creates a barrier that blocks ozone, UV light, oxygen, and moisture. This is the corrosion and weathering resistance principle in action. It does not crack, become brittle, or degrade in tropical conditions.
Mechanical Resistance: High hardness and high toughness formula. It resists abrasion, cutting, and tearing – essential when the cable drags over rock or soil.
Flame Resistance: Inherently flame-retardant due to chemical composition, meeting EN 60332 standards.

Why Standard Cables Fail and How PROTOLON Solves It

To truly appreciate the value of this technology, we must analyze why conventional cables fail in mining and exactly how PROTOLON(M)-R LWL overcomes these limitations. This comparison is based on decades of field data from mines in Indonesia and worldwide.

Failure Modes of Standard MV Cables in Mining

1. Conductor Breakage – The Fatigue Failure

The Problem: Standard cables use Class 2 or Class 5 copper stranding. When bent repeatedly, the thick wires experience high mechanical stress. After 500 to 2,000 bending cycles, metal fatigue sets in, and wires snap. Eventually, the core breaks completely.

Why it happens: The design prioritizes conductivity, not flexibility. The physics of bending dictate that thicker materials suffer higher strain.

The PROTOLON Solution:

Technology: Class FS Extra-Fine Stranding.
Mechanism: Thousands of ultra-thin wires share the load. Strain per wire is reduced by 80% or more.
Result: Survives over 10,000 cycles without a single break. Lifespan increases from months to years.

2. Insulation Cracking – The Environmental and Mechanical Failure

The Problem: Standard cables use PVC, PE, or basic EPR. These materials have low elongation (often <100%). When the cable bends, the insulation stretches beyond its limit and micro-cracks form. Water, dust, and ozone enter these cracks. Over time, "water treeing" occurs – a chemical process that eats away the insulation until it fails electrically.

Why it happens: Materials are chosen for cost and ease of extrusion, not for dynamic or outdoor use.

The PROTOLON Solution:

Technology: PROTOLON 3G13 EPR Insulation + Field Control.
Mechanism:
1. Material: 300% elongation – it stretches and returns to shape without cracking.
2. Chemistry: High cross-link density + ozone-resistant formula – molecular bonds cannot be broken by UV or oxygen.
3. Electrical: Smooth electric field eliminates stress concentrations.
Result: Insulation remains intact and electrically perfect for 5+ years, even in the rain and heat of Sumatra.

3. Sheath Rupture and Abrasion – The Physical Failure

The Problem: Standard outer sheaths are thin and made of NBR or low-grade rubber. They wear through quickly when dragged over rough ground or crushed between layers on a reel. Once the sheath is gone, the core is exposed, and the cable is unsafe.

Why it happens: Lack of reinforcement and poor material formulation.

The PROTOLON Solution:

Technology: Polyester Braid Reinforcement + CR Outer Sheath.
Mechanism:
1. Reinforcement: The braid acts as internal armor, absorbing tensile and torsional forces so the sheath does not have to.
2. Material: CR rubber is 3 times more resistant to abrasion and tearing than standard compounds.
Result: Sheath remains intact, protecting the core from water and damage for the full service life.

4. Torsion and Deformation – The Operational Failure

The Problem: When a cable winds onto a reel, it naturally twists. Standard cables have no structure to resist this. Over time, torque builds up, the cable becomes "corkscrewed", its diameter expands, and it no longer fits on the reel. It becomes unusable even if electrically fine.

Why it happens: Unbalanced lay lengths and lack of anti-torsion elements.

The PROTOLON Solution:

Technology: Optimized Lay Length + Balanced Braid Angle.
Mechanism: The braid is woven at precisely 54°44′ – the theoretical angle for neutral torque. The cable creates its own counter-torque as it bends.
Result: Stays perfectly round and dimensionally stable, even after thousands of winding cycles.

5. Data Loss and Interference – The Operational Blind Spot

The Problem: Mines install separate power cables and separate signal cables. Signal cables are fragile, easily damaged, and suffer from electromagnetic interference (EMI) from high-power lines. Operators fly blind, with no data on equipment health or location.

Why it happens: No integrated solution existed.

The PROTOLON Solution:

Technology: Integrated Fiber Optic Unit.
Mechanism: Fiber is immune to EMI, waterproof, and physically protected.
Result: One cable does two jobs. Reliable data transmission at speeds up to 1 Gbps+, enabling smart mining.

Example: Indonesian Coal Mine

A large open-cast coal mine in East Kalimantan provides a clear case study. Operating 24/7 in high humidity and intense heat, they previously used standard 12/20 kV reeling cables.

Old System: Cables lasted 6 months. They required 8 replacements per year, costing approximately $120,000 annually plus production downtime.
PROTOLON(M)-R LWL: Installed in 2023. After 3 years of continuous operation, the cables remain in perfect condition.
Savings: Over $250,000 saved annually, plus elimination of 16 days of downtime per year.

This is why PROTOLON is not just a product; it is the industry standard.
