Description

Eight to one flexible wire clamp

technical field

The utility model relates to a wire connection device, in particular to an eight-change-one-soft wire clip.

Background technique

In power transmission technology, in order to improve the transmission capacity of the line, each phase is composed of two or more parallel conductors, that is, split conductors. Compared with a single wire, the split wire can reduce the inductance and increase the capacitance of the transmission line, reduce the wave impedance of the alternating current, and improve the power transmission capacity of the line. At the same time, the use of split wires can significantly reduce the field strength on the surface of the wires and improve line stability.

In existing ultra-high voltage substations, the wires of the power distribution device usually use double-split aluminum alloy wires, and the equipment clamps used are double-split wire clamps. However, due to the higher electric field intensity on the surface of the wire in the DC test line section of the UHV test and research base, the environmental impact caused by corona discharge is more prominent, especially the problems of audible noise, radio interference and electrostatic induction. , need to use eight-split aluminum alloy wire. However, the existing equipment clamps can only change the wire mesh to 1/2 of the original size, and therefore cannot meet the requirements of the eight-split wire.
