AI Technical Summary

Technical Problem

Traditional conductor shielding methods for intermediate joints of medium-voltage power cables are inefficient, prone to failure, and the method of wrapping semi-conductive tape is difficult to guarantee sealing and stability.

Method used

A novel prefabricated intermediate cable joint is designed, comprising a joint tube and a quick inspection mechanism. The internal connection can be observed through a transparent cover, and a seal is achieved by the cooperation of a sealing ring, a retaining ring, and a sealing strip. Internal inspection and operation can be carried out without disassembly.

Benefits of technology

It improves the sealing performance and practicality of the intermediate joint, ensures the stability and convenience of the connection, and avoids the joint failure problem caused by improper winding in traditional methods.

Abstract

The utility model relates to a novel cable prefabricated intermediate joint, including opening, the middle part of opening is provided with transparent cover, the outside left and right two ends of joint pipe are all fixedly connected with installation shell, the outside top wall middle part of installation shell is all fixedly connected with L shaped board, two groups of L shaped board top wall middle part are all screw thread connection with screw rod in the side close to each other, the bottom of screw rod all is connected with arc plate that rotates, the front and back two sides of arc plate top wall are all fixedly connected with limit rod, limit rod all are connected in the inside of limit hole and slide, and the limit hole is set respectively in the front and back two parts of the side close to each other of two groups of L shaped board, and the opening is set in the middle part of joint pipe top wall. This kind of novel cable prefabricated intermediate joint, through with the two groups of cable after moving joint pipe to make it with both sides fixed cover connection, rotates fixed cover and makes joint pipe move to fixed cover one side, to fill the connection gap between joint pipe and fixed cover under the cooperation of sealing washer, fixed ring and sealing strip, improves joint sealing performance.
