Type MP-GC stands for:
Mine Power cable
With Ground and Check conductor
It is a medium-voltage, flexible power cable used to supply stationary or semi-portable mining equipment. MP-GC cables are ruggedly constructed to handle extreme mechanical, thermal, and environmental conditions commonly encountered in underground and surface mines.
Three insulated copper conductors for power
One or more ground conductors
One ground check (GC) conductor for safety monitoring
Insulation and jacket materials with excellent flame, oil, abrasion, and water resistance
Type MP-GC cables are typically used for:
Permanent or semi-permanent power feeders in mines and quarries
Supplying stationary or slow-moving mining equipment such as:
Pumps
Crushers
Hoists
Conveyors
Substations
Underground and surface mining operations
Installations in conduits, ducts, or direct burial
Not suitable for dynamic reeling, trailing, or frequent flexing
