Copper Concentric Cable Application

The copper 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 refers to a cable with two concentric conductors, and the conductor and the shield layer share the same axis. It is usually used in distribution networks, current surface boards, meters or circuit panels, which can be placed directly underground or outdoors , Even suitable for dry and humid environments, can support high-bandwidth communications on relatively long lines without repeaters.
