Concentric Cable

Application

The concentric cable is used in electric service entrance from the power distribution network to the meter pannel(especially where it is required to prevent electricity theft), and as feeder cable from the meter pannel to the distribution pannel.
This cable an be used in dry and wet places, outdoors or directly buried.It has a maximum operating temperature of 90ºC and rated voltage of 600V&below.
concentric cable 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.
