Abstract

The invention relates to an application and a preparation method of a copper-aluminum transitional composite connecting bar and a longitudinal multistage connecting bar which belong to connecting materials in the field of power transmission. according to the invention, an ultra-thin copper substrate and an ultra-thin aluminum substrate are compounded through a detonating cord in an explosive welding way to form the connecting bar with the thickness less than 1mm, so that the connecting bar has good flexibility and good connecting performance, is easy to secondary shaping and cutting, has transitional conductive capability and is applicable to the embedded coil knuckle transitional connection in a curly state, transitional connection in a spiral winding mode, transitional connection of the substrate in a plane state, ectopic connection of a high-current line board and the like. The connecting bar can effectively solve the structural problems of a conventional longitudinal copper-aluminum transitional device, improves the wiring reliability, reduces the transmission resistance and heating loss and prolongs the service life of electric power facilities.

Description

technical field [0001] The invention relates to a transition strip used for wire or cable connection in the field of power transmission, in particular to an application and manufacturing method of an ultra-thin copper-aluminum transition composite strip and a multi-stage composite strip. Background technique [0002] In the power supply and distribution system, due to cost factors, aluminum materials are mostly used for long-distance overhead conductors or short-distance cables, and conductors made of aluminum materials are widely used. On the other hand, all kinds of power equipment fittings and electrical appliances are mostly made of copper terminals. If the two are directly connected, the contact resistance will be large. When the equipment is operated for a long time, overloaded or short-circuited, the connection will heat up rapidly, causing derivative operation accidents . [0003] Therefore, copper-aluminum transition devices welded by special processes are genera...
