Two fine aluminium twisted wires are connected between body, two fine aluminium twisted wire parallel distributions are in the first pipe busbar and the second pipe busbar
Both sides, the end of each fine aluminium twisted wire is welded with the pipe mother overcurrent gold utensil body；The pipe mother corner support
Component includes support mounting plate, is fixedly connected with the female support gold utensil bodies of two pipes in the same side of the support mounting plate, and two
A female support gold utensil body of the pipe is respectively sleeved on the first pipe busbar and the second pipe busbar and is pacified by fastening bolt
Dress is fixed, and the ring flange on the opposite side and support insulator of the support mounting plate is bolted.
The bolt hole for being used to be connected with the ring flange in the support mounting plate is kidney slot.
The bending place of the fine aluminium twisted wire uses arc-shaped transition.
Due to taking above technical scheme, it has the following advantages the present invention：1st, the present invention can solve ± 320kV the changes of current
Inner tube of standing bus corner support, overcurrent and it is anti-corona the problems such as, wherein, overcurrent armour clamp assembly of the invention plays the role of water conservancy diversion,
Between the pipe busbar of corner, path is formed so as to fulfill the overcurrent between the pipe busbar of two corners；And pipe mother's corner
Support component is installed on the ring flange of support insulator, plays the role of fixed support tube busbar；And pipe mother's overcurrent gold utensil sheet
What the rounding off design and fine aluminium twisted wire of the female support gold utensil body itself of body, pipe curved after radian itself anti-corona can solve
The anti-corona problem of the present invention.
