Applications

For the connection of electrical equipment,in mines and underground excavations with hazardous environments under particularly high mechanical loads, e.g.high-voltage transformers on power lines in underground mining and tunnelling.The flexibility of the cable allows operating equipment to be moved while running.The phase-concentric earth conductor and the common-concentric monitoring shield,e.g. in conjunction with a high-voltage protection circuit, make it possible to monitor the cable for insulation faults and damage resulting from external influences.

Construction

Conductors: Flexible stranded copper conductor, class 5 according to DIN VDE 0295.

Inner Conductor Layer: Special rubber compound, conductive.

Insulation: Rubber type 3GI3.

Outer Conductor Layer:Special rubber compound, conductive, easy strippable.

Pilot Cores (optional):Tinned copper conductor with EPR insulation.

Earth Conductor: Spiral of tinnedcopper wires.

InnerSheath: Rubber type GM1b.

Monitoring Shield/Armour:Braided armour of combined copper-steel wires; or wrap of copper andsteel wires, copper tape in opposite direction, reinforcing tape.

Outer Sheath: Rubber type 5GM5.
