铜包钢绞合导体与铜钢混绞导体的耐蚀性比较

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.

Anticorrosion Comparison of Conductors Intertwisted with Copper-Clad Steel Wires and Conductors of Steel Wires Entwined with Copper

Through analysis in the principle of electrochemical corrosion, it was found that the anticorrosion capability of the field telephone wire conductors intertwisted with copper-clad steel conductor is three times that of the copper entwined with steel. Compared with the steel wire entwined with copper wire conductor or screening layer normally used in the armed equipment, the copper-clad steel wire has better corrosion resistance, electronic, magnetic and mechanistic properties. It is a fine electromagnetic screening conductive material that provides a possible anti-corrosion way to design and improve the property of the military cable.
