Each core may be formed by twisting a single wire or a plurality of wires according to the requirement of laying and using conditions on the flexibility degree of the cable. Insulating layer: the insulating material used as the cable should have high insulation resistance, high breakdown field strength, low dielectric loss and low dielectric constant. Common insulating materials used in cables are oil-impregnated paper, polyvinyl chloride, polyethylene, crosslinked polyethylene, rubber, and the like. Sealing the sheath: protecting the insulated wire core from mechanical, moisture, humidity, chemicals, light, etc. For moisture-sensitive insulation, a lead or aluminum extrusion seal jacket is generally used. Protecting the covering layer: to protect the sealing boot from mechanical damage. Galvanized steel strips, steel wires or copper strips, copper wires and the like are generally used as armor to wrap the armor outside a sheath (called an armored cable), and the armor layer simultaneously plays the roles of shielding an electric field and preventing external electromagnetic wave interference.
The cable is rolled up at the general lapping of transportation and is made, therefore the cable has certain anti power of buckling, but the cable is in installation or use, often can unexpected the bending degree of buckling range when being far greater than the book system, when taking place great bending failure in time reconversion, the bending point that leads to the cable easily is in fatigue state all the time, lead to this department more other positions faster ageing easily, very easily produce the crack, local damaged condition appears even in the time of seriously, there is certain potential safety hazard.
