CONCENTRIC CABLE

CONCENTRIC CABLE FOR AFRICA MARKET

APPLICATION

The concentric cables are used as electric service entrance from the power distribution network until the meter panel 

(especially where it is required to prevent “black”losses or electric power robbery),and as feeder cable from the meters panel until the panel or general distribution panel, just as it is specified in the National Electrical Code. This type of conductor can be used in dry and wet places, directly buried or outdoors, its maximum temperature of operation is 75℃ and its voltage of service for all the application is 600v.

Construction

  1. Earth Conductor: Solid Aluminum wire
  2. Insulation: XLPE
  3. Phase Conductor: Solid Aluminum wire
  4. Communication Core: Solid Copper wire 
  5. Insulation: LLDPE
  6. Ripcord: Nylon
