SHD-PCG stands for:
Shielded
Heavy-Duty
Power
Conductor
Ground check
SHD-PCG cables are designed for medium-voltage (2 kV or 5 kV) power supply to heavy mining equipment. They include:
Three insulated power conductors
Grounding conductors
A ground check conductor (GC) for monitoring ground continuity
Shielding for electrical safety and EMI control
These cables are extremely robust, flexible, and resistant to harsh mining conditions such as mechanical abuse, moisture, oils, and chemicals.
SHD-PCG cables are primarily used for:
Underground and surface mining operations
Powering heavy mobile equipment like shovels, drills, crushers, and haul trucks
Applications requiring:
Ground fault monitoring
Shielding for EMI protection
Enhanced mechanical protection
Trailing or reeling in moderate flexing conditions (not constant dynamic reeling)
These cables are also suitable for industrial use in tunnels, quarries, and heavy-duty portable equipment installations.
