Description

(N)TSCGECWOEU MV Trailing Cable

(N)TSCGECWOEU MV Mining Trailing Cable Application

(N)TSCGECWOEU Medium-Voltage Mining Trailing Cable is used 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 tunneling.

The flexibility of the cable allows operating equipment to be moved while running.The phase-concentric earth conductor and the common concentric monitoring screen,e.g. in conjunction with a high-voltage protection circuit, make it possible to monitor the cable for insulation faults and damage that are produced by external effects.

These mining trailing cables are used in underground mines as well as in tunnels if monitoring of outer damages is required. The robust construction allows the cable to be used on mobile equipment, on energy lines, as well as for occasional reeling.

For particularly high mechanical stressing, the Braided armor of tinned steel wires is supplemented under the outer cable sheath. This armor serves as an external earthed screen.
