(N)3GHSSHCH 6-20 kV LSZH Mining & Tunneling Cable

(N)3GHSSHCH Cable for Shiftable Mining and Tunnel Equipment

(N)3GHSSHCH cable is a flexible medium-voltage power cable for shiftable equipment and feeder connections in mines, tunnels and underground construction. The supplied range covers 3.6/6 kV, 6/10 kV, 8.7/15 kV and 12/20 kV size data, with separate 18/30 kV voltage and test references. Class 5 copper conductors, EPR insulation, semiconductive field-control layers, protective and monitoring conductors, steel-wire braid and a halogen-free flame-retardant sheath combine electrical control with mechanical protection.

Select this construction where a mining or tunnelling route needs a screened, monitored MV cable that can tolerate movement within the stated temperature, torsion, travel-speed and direction-change limits. It is not an automatic substitute for a continuous high-speed reeling cable or a submersible cable; confirm the movement pattern, route and environmental exposure before ordering.

• Suitable for: shiftable MV mining equipment, tunnel systems and transformer feeder connections.
• Confirm before ordering: Uo/U voltage, phase size, protective and control-core arrangement, cable length and route.
• Mechanical inputs: movement frequency, bend path, torsion, travel speed and pulling load.
• Documentation: required standards, tests, marking, inspection and packing.

Review the mining and tunneling cable range or use the TBM cable selection guide when the route includes a cable reel or moving tunnel-boring equipment.

(N)3GHSSHCH Cable Construction

The construction places field-control, protective and monitoring elements around flexible EPR-insulated power cores, then adds halogen-free inner layers and steel-wire braid. This arrangement is intended for medium-voltage mining and tunnelling routes where the cable must combine electrical screening with controlled movement and mechanical protection.

Construction Checks for a Replacement Cable

Do not cross-reference by voltage and conductor size alone. Compare the protective-conductor layout, pilot/control cores, monitoring conductor, field-control layers, braid, outer diameter and movement limits against the existing cable marking and equipment requirements.

(N)3GHSSHCH Mining Cable Applications

This cable is used as a medium-voltage power connection where mining or tunnelling equipment is shifted during operation or where a robust monitored feeder is needed between electrical equipment. The final choice depends on the route, movement and equipment interface, not only the voltage class.

• Shiftable underground mining machines and mobile operating equipment.
• Tunnel construction and excavation equipment power supply.
• Medium-voltage feeder connections for underground transformers and distribution equipment.
• Mine and tunnel routes requiring protective, pilot/control and monitoring conductors.
• Installations requiring a halogen-free flame-retardant sheath and steel-wire braid.

Movement and Route Boundaries

Use the supplied limits as engineering inputs: +5°C to +80°C for mobile service, maximum travel speed 30 m/min, maximum torsion 25 deg/m, maximum tensile load 15 N/mm² and a 20 x cable-diameter minimum direction-change distance. Confirm rollers, sheaves, pulling method and reversal frequency. Choose a purpose-designed reeling cable for continuous drum duty and a separately qualified construction for immersion or other conditions not stated in the supplied data.

Information Needed for an RFQ

Provide Uo/U voltage, phase-conductor size, protective and control-core arrangement, installed and moving length, equipment, movement cycle, minimum bend path, pulling load, sheath colour, marking, standard and inspection requirements.
