Joint of carbon fiber composite core wire

Abstract

The invention discloses a joint of a carbon fiber composite core wire, which comprises a steel anchor and a jumper conductor clamper which is connected with the steel anchor. The terminal section of the steel anchor is provided with an inner layer press-connection pipe, an outer layer sleeve is coated outside the inner layer press-connection pipe, the inner layer press-connection pipe is provided with a hollow cavity, and the carbon fiber composite core wire inner core to be connected can be inserted into the hollow cavity. Due to the inner layer press-connection pipe and the outer layer sleeve coated outside the inner layer press-connection pipe, when the carbon fiber composite core wire is performed with clamping press fit, force of the press fit is pressed on the wire through two layers of pipe walls, so that the force of the press fit can be dispersed to the stressed steel anchor, uniformity of force loaded on the carbon fiber composite core wire is guaranteed, and grip strength of the joint on the carbon fiber composite core wire is improved. The structure of the joint is simple and reasonable, anchor connection is convenient and reliable, borne force is reasonable, and the joint is widely used for erecting transmission lines of the carbon fiber composite core wire.

Description

technical field [0001] The invention relates to an accessory for an overhead power transmission line in a power system, in particular to a joint of a carbon fiber composite core conductor. Background technique [0002] Traditional power transmission is carried out through steel-cored aluminum conductors. Since such conductors are greatly affected by temperature during power transmission, sag problems will occur. At present, there is a new type of carbon fiber composite core conductor, which is composed of most carbon fibers. , compounded with a resin base material composed of various substances, the wire core is wrapped by a conductor, because this wire core has a higher elastic modulus and a lower thermal expansion coefficient, it can increase the ampacity of the wire, not only Large power transmission, high temperature resistance, no obvious sag, good use effect and long life. It can be said that this is the development trend of power transmission wires. [0003] Carbon f...

AI Technical Summary

Problems solved by technology

[0003] Carbon fiber composite core wire is a new type of wire, and its matching fittings will also become an important part of the application and promotion of carbon fiber composite core wire. The currently used carbon fiber composite core wire supporting joints are wedge-shaped force, spiral connection, etc. And the structure is relatively complex, and has high requirements for construction technology, which is not conducive to large-scale application
