Type SHD-GC 8kV Three-Conductor Round Portable Power Cable TPU Jacket to ICEA S-75-381

What Is Feichun Type SHD-GC 8kV Mining Cable Used For?

The Type SHD-GC 8kV cable is a heavy-duty portable power cable designed for supplying power to large mobile mining equipment, including:

• Draglines and electric shovels

• Drilling rigs and blast hole drills

• Dredges and crushers

• High-capacity power feeders in surface and underground mines

Its 8kV voltage rating, combined with superior mechanical protection, makes it suitable for medium-voltage distribution where flexibility, durability, and safety are essential.

How Is the Feichun SHD-GC 8kV Cable Constructed?

The cable’s construction follows a layer-by-layer safety philosophy, optimized for mining hazards.

What Type of Conductor Is Used?

• Stranded annealed tinned copper

• Offers excellent flexibility, corrosion resistance, and conductivity

• Ideal for damp, abrasive mining environments

Why Is EPR Used as Insulation?

• Ethylene Propylene Rubber (EPR) provides:

  • High dielectric strength

  • Resistance to heat, moisture, and ozone

  • Stable performance up to 90°C conductor temperature

How Does Shielding Improve Safety?

The cable includes:

• Conducting insulation shield

• Conducting tape + tinned copper/textile braid insulation shield

This ensures:

• Uniform electric field distribution

• Reduced electrical stress

• Safer operation at medium voltage levels

What Is the Role of Ground and Ground-Check Conductors?

• Grounding conductor: Ensures fault current is safely discharged

• Ground-check conductor: Enables continuous monitoring of grounding integrity

• Yellow polypropylene insulation allows easy identification during installation and inspection

Why Choose a TPU Jacket Instead of PVC or CPE?

The black Thermoplastic Polyurethane (TPU) jacket offers:

• Exceptional abrasion resistance

• High tensile strength

• Excellent resistance to oils, fuels, and chemicals

• Superior flexibility in cold and hot climates

This makes TPU particularly suitable for dragging, reeling, and continuous movement.

Why Is ICEA S-75-381 Important for Mining Cables?

ICEA S-75-381 (also known as NEMA WC 58) is one of the most widely accepted standards for portable power cables in mining and industrial applications.

Compliance ensures that the cable meets strict requirements for:

• Electrical insulation integrity

• Mechanical durability

• Grounding and ground-check safety

• Thermal performance at elevated temperatures

Feichun SHD-GC 8kV also aligns with:

• ASTM B172 & ASTM B33 (tinned copper conductors)

• CAN/CSA C22.2 No. 96 (portable power cable safety)

Where Is SHD-GC 8kV Used in South African Mines?

South African Case Study: Open-Pit Platinum Mine

In a Limpopo open-cast platinum mine, Feichun SHD-GC 8kV cables were deployed to power electric shovels and drills exposed to:

• Sharp rocks and abrasive soil

• UV radiation and high temperatures

• Constant dragging across pit floors

Results after 18 months:

• Zero insulation failures

• Reduced downtime due to cable damage

• Improved safety compliance with grounding systems

Mine engineers highlighted the TPU jacket’s abrasion resistance as a key performance advantage.

What Are the Best Installation Practices for SHD-GC 8kV?

How Should the Cable Be Installed?

• Respect the minimum bending radius (8×OD)

• Avoid sharp edges and crushing points

• Use cable rollers or skid plates where dragging occurs

How Can Cable Life Be Extended?

• Regularly inspect jacket abrasion

• Monitor ground-check continuity

• Store cables away from direct sunlight when not in use

Frequently Asked Questions (FAQ)
