What Is a Feichun Type W Single Conductor Portable Power Cable 2kV?
A Type W Single Conductor Portable Power Cable (2kV) is a heavy-duty flexible power cable designed for mobile mining and industrial equipment that requires continuous movement, frequent reeling, and high mechanical durability.
The Feichun Type W cable is manufactured in accordance with ICEA S-75-381 / NEMA WC 58 and CAN/CSA C22.2 No.96, making it suitable for both North American and international mining operations, including South African underground and surface mines.
Unlike multi-core portable cables, the single-conductor Type W design allows:
Higher current capacity per conductor
Easier phase separation in high-power systems
Improved flexibility for reel-fed equipment
How Is the Feichun Type W Single Conductor Cable Constructed?
What Type of Conductor Is Used?
Stranded annealed tinned copper conductor
Fine stranding improves flexibility
Tin coating enhances corrosion resistance, especially in humid or acidic mine environments
Why Is EPR Insulation Used?
EPR (Ethylene Propylene Rubber) insulation provides:
Excellent dielectric strength
Heat resistance up to 90°C
Superior flexibility compared to PVC
Resistance to moisture and chemicals
What Is the Purpose of the Polyester Braid Reinforcement?
A polyester braid layer is applied between the insulation and outer sheath to:
Increase tensile strength
Improve resistance to crushing and tearing
Maintain cable integrity during reeling operations
This reinforcement is a key reason Type W cables outperform lighter portable cables in mining.
Why Is a CPE Outer Sheath Commonly Used?
Chlorinated Polyethylene (CPE) outer jacket:
High abrasion resistance
Oil and chemical resistant
Flame retardant
Excellent weathering performance
Optional sheath materials such as CSP, PCP, NBR, or PVC can be supplied for specific site conditions.
Why Is Type W Single Conductor Cable Used in Mining Applications?
Mining environments impose extreme demands on portable power cables. Type W single conductor cables are specifically engineered to handle:
Constant flexing and bending
Reeling and unreeling on cable drums
Mechanical impact and abrasion
Heat, moisture, oil, and chemicals
Typical Mining Applications Include:
Electric mining locomotives
Gathering-reel mobile equipment
Shuttle cars and auxiliary power feeds
Trackless mobile machinery (TMMs)
In South Africa, these cables are commonly found in gold, platinum, and coal mines, where equipment mobility and electrical reliability are critical.
What Standards Does Feichun Type W Single Conductor Cable Comply With?
Compliance is essential for safety, insurance, and regulatory approval.
Applicable Standards:
ICEA S-75-381 / NEMA WC 58 – Portable power cable construction and performance
CAN/CSA C22.2 No.96 – Canadian safety standard for portable power cables
ASTM B172 & ASTM B33 – Tinned copper conductor requirements
These standards ensure:
Electrical safety at 2kV rating
Mechanical durability under repeated flexing
Thermal stability at elevated temperatures
What Are the Recommended Installation Practices?
How Should Type W Cable Be Installed?
Maintain minimum bending radius (≥ 6× OD)
Use smooth, properly aligned cable reels
Avoid sharp edges and uncontrolled tension
Ensure proper strain relief at termination points
What Maintenance Practices Extend Cable Life?
Regular visual inspection for jacket damage
Monitor hotspots near terminations
Clean accumulated debris on reels
Replace damaged sections promptly
Frequently Asked Questions (FAQ)
