Applications:

These cables are used for the connection of mobile operating equipment, in mines and underground excavations with hazardous environments, in stationary operation, e.g. high-voltage transformers in mining and tunnelling.Flexible cable for energy supply to MV equipment in tunnelling and underground mining applications. Suitable for indoor and outdoor applications.

For the connection of mobile operating equipment, in mines and underground excavations with hazardous environ-ments, in stationary operation, e.g.
high-voltage transformers in mining and tunnelling, which are shifted forward in stages as excavation work progresses, in particular in 10 kV networks and -due to the low capacitance of the cables – in expanded 5 kV networks.The mobility of the cable means it can be laid in containers and can be unwound from these as working operations progress. The phase- concentric earth conductor and the common concentric monitoring shield,
in conjunction with a high-voltage protection circuit, make it possible to monitor the cable for insulation faults and damage resulting from external influences.
