Power cable terminal abutting pipe with shielding layer and shielding layer manufacturing method

Abstract

The invention provides a power cable terminal abutting pipe with a shielding layer and a shielding layer manufacturing method. The power cable terminal abutting pipe with a shielding layer is characterized in that the abutting pipe comprises a male abutting pipe and a female abutting pipe; both the male abutting pipe and the female abutting pipe are composed of outer pipe walls and inner pipe walls; the male abutting pipe comprises a first connector, a first pipeline and a male abutting head; the female abutting pipe comprises a second connector, a second pipeline and a female abutting head; the male abutting head has an outer thread structure; the female abutting head has an inner thread structure; the male abutting head and the female abutting head are screwed and fastened via the outer thread and the inner thread; the first connector and the second connector are outer thread connectors and are fastened via nuts; when the nuts are used for fastening, apertures of the first connector and the second connector become small, and the power cable is fixed; and the abutting pipe also comprises a shielding layer. According to the abutting pipe of the invention, signal transmission can be prevented from being influenced by outer interference, two ends of the abutting pipe are provided with sealing pads, and the sealing pads are also provided with the shielding layers.

Description

technical field [0001] The invention relates to the technical field of electric power auxiliary equipment, in particular to a power cable lug butt joint tube with a shielding layer and a preparation method for the shielding layer. Background technique [0002] Power cable (power cable), a cable used to transmit and distribute electrical energy. It is often used in urban underground power grids, outgoing lines of power stations, internal power supply of industrial and mining enterprises, and underwater transmission lines across rivers and seas. In power lines, the proportion of cables is gradually increasing. Power cables are cable products used to transmit and distribute high-power electric energy in the main line of the power system, including 1-500KV and above various voltage levels and various insulated power cables. [0003] Cable terminals are generally used for multiplexing, connection, bridging, and transfer in power cables. The connection of general power cables is...

AI Technical Summary

Problems solved by technology

[0003] Cable terminals are generally used for multiplexing, connection, bridging, and transfer in power cables. The connection of general power cables is also terminal, but the general terminal does not have a shielding layer, so due to the need for power cable connection, It is necessary to destroy the original shielding layer of the original power cable, so that there is no shielding layer at the joint, which will inevitably cause signal loss in the process of power and signal transmission, because there are more interference signals in the signal, which will affect the transmission of the signal ; so these problems need to be solved urgently
