TUNNEL CABLES

NSHCGEöU KON+ST+UL

It is used for connection of mobile machines with very high mechanical load, especially in mines for coal cutting

and loading machines as well as for supplying appliances and auxiliary and auxiliary electrical circuits. Concentric

phase monitoring screen and overall concentric earth conductor facilitate in connection with a suitable

monitoring equipment monitoring of the cable from standpoint of insulation faults and damages that are caused

by external effects.
