通过电化学腐蚀原理的分析,认为被复线用铜包钢绞合导体是用铜钢混绞导体耐蚀性的3倍,有效提高了被复线的野外使用性能。与装备电缆通用的钢丝、铜丝混绞或混编导体或屏蔽层相比,铜包钢丝还兼有更好的耐蚀性、导电性、导磁性和力学性能,是一类优良的电磁屏蔽用导体材料,为装备线缆的设计采用和性能提高提供了防腐依据。 Through the analysis of the electrochemical corrosion theory, it is considered that the copper-clad steel stranded conductor for the double-stranded wire is 3 times of the corrosion resistance of the copper-steel stranded conductor, effectively improving the field performance of the double-stranded wire. Compared with the common wire, copper wire mixed or mixed conductor or shielding layer, the copper coated steel wire also has better corrosion resistance, conductivity, permeability and mechanical properties, which is a kind of excellent electromagnetic shielding Conductor material is used to provide a basis for corrosion protection on the design and performance of equipment cables.
