In underground and surface mining operations, power reliability is not optional—it is a safety requirement. As mines expand deeper and equipment loads increase, selecting the right Mine Power Feeder Cable becomes critical. One of the most widely specified designs for fixed and semi-fixed mine power distribution is the ICEA S-75-381 Type MP-GC Three-Conductor Mine Power Feeder Cable (5kV, CPE Jacket).

What Does “Type MP-GC” Mean in Mining Power Cables?

Type MP-GC is a classification defined under ICEA S-75-381 / NEMA WC 58, specifically for Mine Power Feeder Cables used in mining distribution systems.

MP = Mine Power
GC = Ground Check conductor included

Unlike trailing or reeling cables, MP-GC cables are designed for feeder circuits, supplying power between substations, switchgear, transformers, and load centers.

How Is a Type MP-GC Mine Power Feeder Cable Constructed?

The strength of the Type MP-GC cable lies in its multi-layered, safety-oriented construction.

What Type of Conductor Is Used?

Stranded annealed bare copper
Manufactured to ASTM B-8
High flexibility compared to solid conductors
Excellent conductivity and fatigue resistance

Why Is a Conductor Shield Necessary?

A conductive shield layer surrounds each conductor to:

Control electric stress
Prevent partial discharge
Improve insulation life at 5kV

What Insulation Material Is Used and Why?

EPR (Ethylene Propylene Rubber) insulation
Rated for 90°C continuous operation
Superior resistance to:
- Moisture
- Heat aging
- Electrical stress
- Ozone and chemicals

What Is the Role of the Insulation Shield and Copper Tape?

Conductive insulation shield + copper tape
Ensures:
- Uniform grounding
- Fast fault current dissipation
- Improved personnel safety

Why Are Separate Grounding and Ground-Check Conductors Included?

Grounding Conductor: Tinned copper (corrosion-resistant)
Ground Check Conductor: Copper with yellow polypropylene insulation
Enables continuous monitoring of grounding integrity—critical in mines

Why Is a CPE Jacket Used?

The outer Chlorinated Polyethylene (CPE) jacket provides:

High abrasion resistance
Flame resistance
Oil, chemical, and moisture resistance
Long service life in ducts, conduits, and direct burial

Where Are Type MP-GC Mine Power Feeder Cables Commonly Used?

Typical Applications

Underground mine substations
Power feeders between transformers and switchgear
Conveyor power supply systems
Pump stations
Ventilation fan feeders
Fixed mining infrastructure

Installation Environments

Installed in ducts
Installed in conduits
Installed in open air
Direct burial in wet or dry soil

How Does Type MP-GC Compare with Other Mining Power Cables?

MP-GC vs SHD-GC vs G-GC

Feature	MP-GC	SHD-GC	G-GC
Voltage	Up to 5kV	Up to 25kV	Up to 2kV
Application	Power feeder	Mobile equipment	Mobile equipment
Flexibility	Medium	High	High
Ground Check	Yes	Yes	Yes
Installation	Fixed	Trailing/Reeling	Trailing

What Are the Key Installation Recommendations for MP-GC Cables?

Best Practices

Maintain minimum bending radius
Ensure proper grounding and ground-check continuity
Use cable cleats in vertical installations
Avoid sharp rocks in direct burial
Perform insulation resistance testing before energizing

Frequently Asked Questions (FAQ)

Is Type MP-GC suitable for mobile mining equipment?

No. It is designed for fixed or semi-fixed feeder applications, not trailing use.

Can MP-GC cables be directly buried underground?

Yes. They are designed for direct burial in wet and dry conditions.

Why is a ground check conductor mandatory in mining?

It ensures continuous monitoring of grounding integrity, reducing electric shock risk.

Is CPE better than PVC for mining cables?

Yes. CPE offers superior resistance to heat, oil, abrasion, and flame.

Can alternative jacket materials be supplied?

Yes. CSP, PCP, NBR, PVC, and TPU jackets are available upon request.
