The basic structure of the wire cable consists of a conductor, insulation, armored sheath composition, its general structure is as follows: a. Conductor: the cable having a lot of features on current conduction element. (b) insulation; cable has to withstand a lot of features of the voltage, insulation effect of the material. c filler: To cabling round together with insulated stranded linear material. d. package with: multi-core cable to cable package tight, to avoid injuries to the cable core, damp and wrapped in a cable core ribbon material. e lining layer: packet in the multi-core cable core and non-metallic layer placed under the protective layer. f armor layer: In order to prevent external mechanical impact by a metal strip or wire wound on the core outer cover layer. g jacket: metal or non-metallic material is uniformly continuous extruded cable core insulation protection.
