同向绞合软铜导体的设计及应用

采用股线绞向与复绞绞向相同的设计法,对第5种和第6种软铜导体进行绞合,对相同截面的导体,可适当降低导体的直流电阻和铜材消耗,有效改善绞合导体表面的圆整性和表面质量,并减小导体的绞合外径.对用于高压软电缆导体的普通绞合导体进行电性能综合对比分析,认为此类导体可使导体表面电场均匀,有利于提高高压橡套电缆综合电性能.

Design and Application of Unidirectionally Stranded Flexible Copper Conductors

When class 5 and 6 flexible copper conductors are made with single wire stranding and rope-lay-stranding having the same direction of lay,for the same conductor cross-section,the conductor DC resistance and copper con-sumption will be reduced moderately;the circularity and surface quality of the stranded conductors will be effectively improved;and the stranding diameter will be reduced.Comparison of electric properties was made between the new type of conductors and the conventionally stranded conductors in...
