Strain clamp for multi-strand stranded reinforced core stranded wire

Abstract

The invention discloses a strain clamp for a multi-strand stranded reinforced core stranded wire. The strain clamp comprises a reinforced core liner tube (1), a steel anchor (2), an outer aluminum tube (3), a filling layer (4) and a drainage wire clamp (5); the reinforced core liner tube (1) is arranged on the end of a reinforced core in a sleeving manner; the reinforced core liner tube (1) is crimped in an inner hole (2-1) in the end part of the steel anchor (2); the outer aluminum tube (3) is arranged on the peripheries of the steel anchor (2) and a non-stripped conductor wire (6) in a sleeving and tightening manner; the reinforced core in the non-stripped conductor wire (6) and the reinforced core in the inner hole (2-1) are connected into an integrated body; the filling layer (4) is positioned between the steel anchor (2) and the outer aluminum tube (3); and a drainage plate (3-1) on the outer aluminum tube (3) is connected with the drainage wire clamp (5) through a bolt to realizeconnection of jumper wires. The strain clamp is reasonable in structural design and convenient to install, capable of realizing effective connection between the reinforced core and the steel anchor,transferring stress uniformly and achieving high wire operation safety, and high in practicability.

Description

technical field [0001] The invention relates to a strain-resistant clamp for multi-strand reinforced core stranded wires in overhead power transmission lines. Background technique [0002] In order to solve the problems that the wires and cables used in the existing long-distance large-capacity power transmission generally use steel-cored aluminum stranded wires as conductors, which consume a lot of energy and have a small current-carrying capacity, resulting in frequent power outages and power failures, organic composite materials are used Instead of metal materials to make the core material of the wire, a new type of composite material synthetic core wire has been developed. This kind of wire has the characteristics of high temperature resistance, large capacity, low energy consumption and long life. Due to the high advantages of this kind of wire, it has been well used in the reconstruction of old lines and new lines. Due to the promotion and application of ultra-high v...

Problems solved by technology

Due to the promotion and application of ultra-high voltage and ultra-high voltage lines, there is a greater demand for large-section conductors, and the limitations of poor bending performance of large-diameter single composite material core conductors have begun to emerge, which has brought a lot of inconvenience to construction and installation. , people have developed a multi-strand stranded reinforcing core to replace a single large-diameter reinforcing core, which can solve the above problems
