Abstract

The invention discloses a manufacturing method of electric wire with high-performance and high life. The manufacturing method of electric wire with high-performance and high life comprises the steps of draw benching, twisting, co-extruding, detecting, looping, warehousing and the like, high purity copper mongline or copper stranded wire is core material, after draw benching, twisting and forming, through three extruder shared with one machine head, core materials, endothecium natural color insulations and exothecium colors insulations are formed by co-extruding. Endothecium uses organosilane crosslinked polyethylene insulation, exothecium uses silane crosslinked halogen-free low smoke antiflaming polyolefin insulation, which has the advantages of halogen-free, low smoke, environmental protection and non-toxic. Formed core materials of electric wire have the advantages of high purity, strong surge capability, double insulation and co-extruding. Overall performance of steam cross-linked insulation is good in whole, an operating temperature is high, service life is prolonged, environmental pollution is rarely in whole link of producing, using and recycling.

Description

technical field [0001] The invention relates to the field of electric wire manufacturing, in particular to a method for manufacturing electric wires with high performance and long service life. Background technique [0002] Ordinary home improvement wires generally use ordinary round copper single wires as conductive cores, and use ordinary PVC insulating plastics as single-layer insulation to extrude to form home improvement wires. It has many advantages as well as its disadvantages: [0003] 1. In order to reduce the cost, the purity of the copper material used in the copper single wire is usually about 99.95%. The purity is not very high, which leads to the weak overload capacity of the wire and high power consumption. [0004] 2. PVC insulation materials are mainly composed of PVC resin, which contains halogen factors, and will release a large amount of toxic smoke when burned; PVC insulation materials are not very adaptable when used in different environments, such as ...
