一种具有高柔软高密度漆包绞线用漆包线的生产工艺
摘要：
本发明涉及一种具有高柔软高密度漆包绞线所用漆包线的生产工艺，通过对导体拉制工艺的创新，根据线规的不同在不同的拉丝过程中加入在线电流退火，使漆包线的伸长率可达20%以上；拉制导体公差的制定，即将导体公差制定为，使得漆包线漆膜在较大扭绞力及挤压力下保持良好的状态；收线张力的合理调节，即将收线张力控制在8～12g，从而制出具有低节距、高密度及高柔软度的漆包绞线，在绞合后的单线伸长率可达到17%以上，同时绞合后整股漆包线的针孔数在5米内不超过10个。
摘要（英）：

The invention relates to a production process for a high-flexibility high-density enameled wire for an enameled stranded conductor. A conductor drawing process is innovated, and line current is added in different wire drawing processes for annealing according to different wire gauges, so that the elongation of the enameled wire can reach over 20 percent; drawn conductor tolerance is formulated, namely the conductor tolerance is formulated to keep a film of the enameled wire in a good state under strong stranding force and extrusion force; and take-up tension is rationally adjusted, namely the take-up tension is controlled to 8 to 12g, so that the low-pitch, high-density and high-flexibility enameled wire is produced, the elongation of a single stranded wire can reach over 17 percent, and meanwhile, the number of pinholes of the whole strand of stranded enameled wire within 5 meters does not exceed 10.
