What Does “SHD-CGC” Mean in a 2kV Portable Mining Cable?
SHD-CGC is a designation used in North American–style mining cables that reflects both mechanical duty level and safety features:
SHD – Super Heavy Duty, designed for severe mechanical stress
C – Ground Check Conductor included
G – Grounding Conductor included
C – Metallic Shielding present
In practical terms, an SHD-CGC cable is built for high-power mobile mining machines that require:
Continuous grounding
Ground-check monitoring
Shielded insulation for enhanced safety
Maximum resistance to crushing, dragging, and abrasion
Why Is a Ground Check Conductor Critical in Underground Mining?
A ground check conductor, centrally located in the Feichun SHD-CGC cable, plays a vital role in mine safety systems.
It allows ground-monitoring relays to:
Detect loss of grounding continuity
Automatically shut down power if grounding fails
Prevent shock hazards to operators
In South African coal and platinum mines, ground-check systems are widely mandated for continuous miners, loaders, and longwall equipment, making SHD-CGC cables a preferred solution.
What Are the Key Electrical and Mechanical Specifications?
What Is the Rated Voltage and Temperature?
Voltage rating: 2kV
Maximum conductor temperature: +90 °C
Minimum bending radius: 6 × overall diameter
This makes the cable suitable for tight underground installations and frequent movement.
What Are the Ampacity Ratings?
Ampacity is based on:
90 °C conductor temperature
40 °C ambient air

Construction | Overall Diameter (mm) | Weight (kg/km) | Ampacity (A) |
|---|---|---|---|
3 × 2/0 AWG | 53.1 | 5059 | 243 |
3 × 3/0 AWG | 56.1 | 5853 | 279 |
3 × 4/0 AWG | 59.9 | 7231 | 321 |
3 × 350 kcmil | 71.4 | 11010 | 435 |
Where Is the SHD-CGC 2kV Cable Typically Used?
What Mining Equipment Requires SHD-CGC Cables?
Longwall shearers
Continuous miners
Load-haul-dump (LHD) machines
Roof bolters
Mobile drills
High-capacity conveyors
Pumps and auxiliary mobile equipment
These machines demand continuous power under constant movement, making SHD-CGC ideal.
What Are the Recommended Installation Practices?
How Should SHD-CGC Cables Be Installed Correctly?
Maintain minimum bending radius during routing
Avoid twisting during deployment
Use compatible mining-rated connectors
Protect cable from sharp edges at entry points
Perform ground-check continuity testing before energizing
Proper installation significantly extends service life.
Frequently Asked Questions (FAQ)
Is SHD-CGC Suitable for Surface Mining?
