Description

A T-shaped clamp for single conductor and double down conductor

technical field

The invention relates to a wire clip, in particular to a T-shaped wire clip with a single conductor and double down-leads.

Background technique

At present, the compressed T-shaped clamp is widely used in large and medium-sized permanent substation projects. It uses pressure to make the aluminum tube and the wire into a whole, so it has good electrical contact performance, extremely stable contact resistance, and less maintenance work. Reliable operation. The finalized compressed T-shaped cable clamp body is an open drawer, which can be installed on a workbench according to the location of the equipment after the main busbar is erected. The compressed T-shaped clamp connects the down conductor with a rectangular terminal. Different specifications of the down conductor can be installed according to the actual engineering needs. At this time, the down conductor should be assembled with the equipment clamp of the corresponding specification. Since there are often two branch wires lapped at the same point of the busbar in the substation project, if the existing compressed T-type clamp is used to connect the double down-lead, the construction is extremely difficult, and the terminal of the T-type clamp It is often impossible to reliably contact with the equipment clamp, resulting in increased contact resistance and a certain potential safety hazard.

The new compressed single-conductor double-lead down-conductor T-shaped clamp is a compressed T-shaped clamp with double terminals designed to solve the problem of two branch conductors overlapping the same point of the busbar. The closest to the present invention is the conventional compression T-shaped clamp. Conventional compression type T-clamp technology is mature and reliable, with wide application range, simple structure and good electrical performance. However, conventional compressed T-type clamps are difficult to solve the problem of overlapping double down-leads. If a single terminal of a T-type clamp is used to connect two equipment clamps, it will not only increase the difficulty of construction, but also cause safety hazards.
