Combined parallel groove clamp

Abstract

The invention provides a combined parallel groove clamp. The combined parallel groove clamp comprises a first cover plate, a first wire clamping plate, a second wire clamping plate and a second cover plate which are arranged in sequence; two first clamping grooves are formed in the side, facing the second wire clamping plate, of the first wire clamping plate; two second clamping grooves are formed in the side, facing the first wire clamping plate, of the second wire clamping plate, and the second clamping grooves correspond to the first clamping grooves and are used for clamping and fixing wires; and through holes are formed in the first cover plate, the first wire clamping plate, the second wire clamping plate and the second cover plate in a stacked mode, the first cover plate, the first wire clamping plate, the second wire clamping plate and the second cover plate are clamped and fixed through bolts penetrating through the through holes, the first wire clamping plate and the second wire clamping plate are made of pure aluminum materials, and the first cover plate and the second cover plate are steel plates. According to the invention, the pure aluminum clamping plate made of the same material as the wire is adopted, so that the occurrence of burn and wire breakage accidents can be reduced, and power transmission is ensured; and a lead is connected and fixed through the cover plate, and use is convenient.

Description

technical field [0001] Embodiments of the present disclosure relate generally to the field of power transmission and distribution, and more specifically, to combined trench clamps. Background technique [0002] At present, in the power transmission and distribution lines, parallel trench clamps are commonly used for tension and branch lead connections. However, since the connection resistance of parallel trench clamps is greater than that of straight-through lines, accidents such as burns and broken wires or poor contact may occur at the connection of parallel trench clamps, which limits the transmission of power and greatly wastes the investment efficiency of transmission and distribution lines. . [0003] Most of the current parallel trench clamps are made of alloy aluminum, which is quite different from the material of the wires. After the power is turned on, it is easy to cause ignition, which in turn leads to accidents such as wire burns and disconnection. Contents o...

Problems solved by technology

However, since the connection resistance of parallel trench clamps is greater than that of straight-through lines, accidents such as burns and broken wires or poor contact may occur at the connection of parallel trench clamps, which limits the transmission of power and greatly wastes the investment efficiency of transmission and distribution lines.

[0003] Most of the current parallel trench clamps are made of alloy aluminum, which is quite different from the material of the wires. It is easy to cause ignition after power-on, which in turn leads to accidents such as wire burns and disconnection.
