Feichun Type G Two-Conductor Flat Portable Power Cable 2kV for Use on D.C. Off-track Mining Equipment

What Is Feichun Type G Two-Conductor Flat Portable Power Cable 2kV?

Feichun Type G is a 2kV-rated flat portable power cable specifically engineered for D.C. off-track underground mining equipment. Its flat construction, heavy-duty sheath, and reinforced design make it ideal for harsh mining environments where cables are dragged, flexed, and exposed to mechanical abuse.

This cable is commonly used on:

• D.C. shuttle cars

• Underground drills

• Cutting machines

• Loading and hauling equipment

Designed to meet ICEA, NEMA, ASTM, and CSA standards, Type G cables balance electrical reliability, mechanical durability, and safety compliance.

Why Does Type G Cable Use a Flat Two-Conductor Design?

How does a flat profile benefit mining operations?

A flat cable profile offers:

• Improved stability when laid on mine floors

• Reduced twisting during equipment movement

• Better heat dissipation compared with round designs

• Easier handling and routing in confined underground spaces

Why two conductors plus grounding?

The two power conductors supply D.C. power, while the tinned copper grounding conductor with green covering ensures:

• Enhanced personnel safety

• Compliance with underground mining electrical regulations

• Reliable fault current return paths

What Standards Does Feichun Type G Cable Comply With?

Which international standards are relevant to Type G cable?

Feichun Type G cable is manufactured in accordance with:

• ICEA S-75-381 / NEMA WC 58 – portable power cable performance

• ASTM B172 & ASTM B33 – tinned copper conductor requirements

• CAN/CSA-C22.2 No.96 – Canadian safety and performance standards

These standards ensure the cable’s electrical integrity, mechanical strength, and long-term durability in demanding mining environments.

How Is Feichun Type G 2kV Cable Constructed?

What materials are used in the conductors?

• Stranded annealed tinned copper conductors

•      Excellent flexibility

•      Superior corrosion resistance

•       Reliable conductivity in damp mine conditions

Why is EPR used for insulation?

• Ethylene Propylene Rubber (EPR) insulation provides:

•     High dielectric strength

•     Resistance to heat and moisture

•     Stable performance up to 90°C operating temperature

What reinforcement improves mechanical life?

• Synthetic yarn reinforcement increases:

•      Tensile strength

•      Resistance to stretching and tearing

•      Service life under frequent dragging

Why is CPE selected for the outer sheath?

The extra-heavy-duty Chlorinated Polyethylene (CPE) sheath offers:

• Outstanding abrasion resistance

• Oil, chemical, and moisture resistance

• Flame-retardant characteristics

Optional jackets such as CSP, PCP, NBR, or PVC can be supplied, including dual-layer jackets with reinforcing fibre for extreme conditions.

How Does Type G Compare with Other Portable Mining Cables?

Type G vs Type W – Which should you choose?

Type G is preferred where D.C. traction and off-track equipment are involved, while Type W is more common in A.C. power distribution.

What Are the Best Installation and Handling Practices?

How should Type G cables be installed?

• Maintain bending radius ≥ 6×OD

• Avoid sharp edges and crushing points

• Secure cables to reduce excessive dragging

• Ensure proper grounding connections

How can service life be extended?

• Regular visual inspections for sheath damage

• Avoid overloading beyond rated ampacity

• Store cables away from direct sunlight and oils when not in use

Frequently Asked Questions (FAQ)

Is Type G cable suitable for A.C. applications?

Type G is primarily designed for D.C. mining equipment. For A.C. systems, Type W or equivalent cables are usually recommended.

Can different jacket materials be customized?

Yes. Feichun offers CSP, PCP, NBR, PVC, and dual-layer reinforced jackets upon request.

Does flat cable reduce mechanical damage?

Yes. Flat cables distribute stress more evenly and resist rolling and twisting, reducing localized wear.

How do I choose the correct conductor size?

Consider:

• Load current

• Cable length and voltage drop

• Ambient temperature

• Mechanical stress level
