Wire and cable As a whole, the structural components of the product can be divided into conductor, insulation layer, shielding and protective layer, as well as filling element and bearing element. that Wire and cable What kind of data is it made of?
1、 Copper wire: electrolytic copper is selected as the material, copper wire made by continuous casting and rolling process is called low oxygen copper wire; copper wire made by up drawing method is called oxygen free copper wire.
2、 Aluminum wire: aluminum wire used for wire shall be annealed and softened. Aluminum wire used for cable shall not be softened.
3、 PVC: PVC plastic is based on PVC resin and mixed with various additives, such as antioxidant, antioxidant, filler, brightener, flame retardant, etc 38-1.46 g / cm3.
4、 Polyethylene: polyethylene is polymerized from refined ethylene and can be divided into low density polyethylene, medium density polyethylene and high density polyethylene according to density.
5、 Crosslinked polyethylene: now Cable There are two types of crosslinked polyethylene that are used professionally. The first is silane crosslinking agent, which is called silane crosslinking material, which is mainly used in the insulation layer of low-voltage wires and cables; the second is cross-linked polyethylene material with diisopropyl peroxide as crosslinking agent, which is mainly composed of polyethylene, crosslinking agent and antioxidant.
