Mine Power Feeder Cable, XLP-PVC , 5000V, 8000V and 15000V

Select the voltage class that meets the operating voltage, insulation requirements, and specifications of the mine power distribution system.

The correct choice should be based on the electrical system design rather than simply selecting the highest available voltage rating. System voltage, grounding method, insulation level, connected equipment, cable length, and applicable mine electrical requirements can all influence the specification. The conductor size must then be selected separately to accommodate the required current and other installation conditions.

The ground check conductor can be used with compatible monitoring equipment to verify continuity of the equipment grounding circuit.

Mine electrical systems often incorporate ground-monitoring systems designed to detect a loss of grounding continuity. The dedicated ground check conductor provides the monitoring circuit with a separate path that can be used to help verify that the grounding system remains intact. Its purpose is different from that of the primary grounding conductors that carry fault current.

The ground wires provide the equipment grounding path, while the ground check conductor supports continuous monitoring of that grounding system.

Although the conductors are contained within the same cable assembly, they serve separate electrical functions. The grounding conductors provide a low-impedance path for fault current, while the insulated ground check conductor can be incorporated into a monitoring circuit designed to detect an interruption in grounding continuity. This distinction is particularly important in mine power distribution systems where ground integrity may be continuously monitored.

Mine power feeder cable is generally intended for fixed or semi-portable distribution, while SHD-GC cable is designed for equipment applications that require substantially more flexing and mechanical movement.

Mine power feeder cable is well suited to distributing power through the mine infrastructure to load centers and other distribution points. SHD-GC cable uses a construction intended for demanding portable and mobile equipment such as shovels, draglines, and similar machinery where repeated flexing, movement, impact, and mechanical stress are greater concerns. The amount of cable movement expected in service is therefore an important factor when choosing between the two types.

Long mine feeder runs should be evaluated for ampacity, voltage drop, system voltage, load characteristics, and installation conditions before conductor size is selected.

A conductor may have sufficient ampacity for the connected load but still produce excessive voltage drop over a long distribution run. Cable length, operating current, starting characteristics of connected equipment, conductor resistance, ambient conditions, and the installation method can all affect performance. Physical factors such as cable diameter and weight should also be considered because larger mine feeder cables can place greater demands on handling, supports, and installation equipment.
