Description
技术领域 technical field
本实用新型涉及一种电缆导体，尤其是涉及一种抗集肤效应的电缆导体。The utility model relates to a cable conductor, in particular to an anti-skin effect cable conductor.
背景技术 Background technique
众所周知，目前我国35kv及以下电缆的导体均采用先在拉丝机上拉制圆铜(铝)线，然后在绞线机上进行分层绞合而成。但是，此种方法绞合的导体是一整块的，当交变电流通过导体时，由于集肤效应的原因，电子的流动都集中在导体的表面，使导体的截面利用率很低，其载流量小、容易发热。为最大限度的利用导体的截面、抗集肤效应、提高导体的载流量，也可以将超高压电缆的导体均做成分割导体：同样截面的导体，用五块扇形的导体拼接而成，块与块之间用绝缘纸隔开，增加了导体的表面积，使导体利用率高。但该种分割导体的制造成本非常昂贵，制造工艺相当烦琐。As we all know, at present, the conductors of cables of 35kV and below in our country are first drawn on a wire drawing machine to draw round copper (aluminum) wires, and then layered and twisted on a stranding machine. However, the conductor stranded by this method is a whole piece. When the alternating current passes through the conductor, due to the skin effect, the flow of electrons is concentrated on the surface of the conductor, so that the cross-sectional utilization of the conductor is very low. Small carrying capacity, easy to generate heat. In order to maximize the use of the cross-section of the conductor, resist the skin effect, and increase the current-carrying capacity of the conductor, the conductors of the EHV cable can also be made into split conductors: the conductors with the same cross-section are spliced by five fan-shaped conductors. It is separated from the block by insulating paper, which increases the surface area of the conductor and makes the utilization rate of the conductor high. However, the manufacturing cost of such segmented conductors is very expensive, and the manufacturing process is rather cumbersome.
