Application

Power cables for energy supply are used for industry and distribution boards, power stations, house connecting boxes and street lighting as well as control cable for the transmission of control impulses and test data. Overall, where increased electrical and also mechanical protection are required. Those cables are installed in open air, in underground, in water, indoors and in cable ducts. The concentric conductor (C) is allowed to use as PE-, PEN-conductor or as shield. due to the typical construction of concentric conductors it is possible to obtain many more cable joints, without cutting any conductor. In that way the operating reliability is guaranteed.
