Ampacity-Based on a conductor temperature of 90℃ and an ambient air temperature of 40℃, per ICEA S-75-381.

In underground and surface mining operations, power reliability is not optional—it is mission-critical. When operators search for “Type MP-GC 8kV mine power feeder cable”, they are usually trying to answer three key questions: What exactly is this cable? Where should it be used? And how does it compare with other mining power cables?

The Feichun Type MP-GC Three-Conductor Mine Power Feeder Cable with PVC Jacket (8kV) is specifically designed for connections between units of mine distribution systems, offering a balance of electrical performance, mechanical robustness, and regulatory compliance under ICEA S-75-381.

What Does “Type MP-GC 8kV” Mean in Mining Power Applications?

The designation MP-GC is not a marketing term—it defines a Mine Power – Ground Check cable designed for medium-voltage distribution in mining environments.

  • MP: Mine Power, suitable for feeder and distribution circuits

  • GC: Integrated ground check conductor for continuous grounding integrity monitoring

  • 8kV: Rated voltage class suitable for mine distribution systems between substations, switchgear, and major equipment

This makes Type MP-GC cables ideal for fixed or semi-fixed installations, unlike highly flexible trailing or reeling cables.

What Is the Purpose of the Ground Check and Grounding Conductors?

Why Is a Ground Check Conductor Required?

The ground check conductor, insulated with yellow polypropylene, enables continuous monitoring of the grounding circuit. If grounding continuity is lost, protective systems can trip power automatically—critical for miner safety.

How Does the Grounding Conductor Enhance Fault Protection?

A tinned copper grounding conductor provides:

  • Low-resistance fault current path

  • Improved corrosion resistance in wet or acidic mine conditions

  • Compliance with ICEA and CSA safety requirements


Why Choose a PVC Jacket for Mine Power Feeder Cables?

The outer jacket is made of black Polyvinyl Chloride (PVC), offering:

  • Resistance to moisture, oils, and chemicals

  • Good abrasion performance in ducts and open installations

  • Cost-effective protection for fixed mining installations

For harsher environments, Feichun also offers CSP, PCP, NBR, CPE, and TPU jackets upon request.


How Do Different MP-GC 8kV Sizes Compare?

Which Conductor Size Should You Choose?

Below is a simplified comparison based on ampacity and application:

Frequently Asked Questions About Type MP-GC 8kV Cables

Is Type MP-GC Suitable for Mobile Mining Equipment?

No. MP-GC cables are designed for fixed or semi-fixed distribution, not continuous movement.

Can PVC Jackets Be Used in Wet Mine Conditions?

Yes. PVC performs well in wet environments, though CPE or TPU may be preferred for extreme mechanical abuse.

Does MP-GC Meet International Standards?

Yes. The cable complies with:

  • ICEA S-75-381 / NEMA WC 58

  • ASTM B-8

  • CAN/CSA-C22.2 No.96
