Steel core copper strands

钢芯铜绞线

Abstract

The utility model provides a steel core copper strands, including locate the center the steel core layer, the steel core layer includes three steel core lines, the steel core line is a nickel plating high -carbon steel wire, the surface of steel core line is equipped with four vertical archs of evenly distributed, the skin on steel core layer is the isolation layer, the steel core layer with it has the insulating cement to fill between the isolation layer, the skin of isolation layer is copper line layer, copper line layer is formed by the transposition of the copper line more than 3 or 3, the skin on copper line layer still is equipped with the protective layer. The utility model provides a steel core copper strands, simple structure, manufacturing cost is lower, has higher intensity, pulling force and better electric conductive property, and through pack the insulating cement in inside, can reduce electrostatic interference, and insulating nature is good, and light in weight is easily practical.
一种钢芯铜绞线,包括设于中心的钢芯层,所述钢芯层包括三根钢芯线,所述钢芯线为镀镍高碳钢丝,所述钢芯线的表面设有均匀分布的四条纵向凸起,所述钢芯层的外层为隔离层,所述钢芯层与所述隔离层之间填充有绝缘胶,所述隔离层的外层为铜线层,所述铜线层由3条或3条以上的铜线绞合而成,所述铜线层的外层还设有保护层。本实用新型提出的钢芯铜绞线,结构简单,生产成本较低,具有较高的强度、拉力及更好的导电性能,且通过在内部填充绝缘胶,可降低静电干扰,绝缘性好,重量轻,易于实用。
