 接触导线是电气化接触网中最重要的线材,要求材质成分均匀,抗拉强度、导电率等性能稳定,全长之内不能有任何内部组织缺陷和表面缺陷,还要平直平顺,耐温、耐磨、耐腐蚀、耐疲劳等。

北赛电工接触线的生产工艺主要包括合金熔炼、连续铸造、连续挤压、轧制、在线探伤、拉拔成型以及热处理等。

 

Contact wire is the most important electrified OHL wire,which requires homogeneous material, steady tensile strength and electrical conductivity. The whole wire couldn’t present any internal or surface imperfections, which should be smooth flat, resist high temperature, abrasion, corrosion fatigue,etc.

The main production technology of BSEC includes alloy melting, continuous casting continuous extruding, rolling, online detection, drawing molding, heat treatment, etc.
