Problems solved by technology

[0002] The cable is the bridge between the power supply equipment and the electrical equipment, which plays the role of transmitting electric energy, and the high-voltage cable is a kind of power cable, which is mostly used in power transmission and distribution. After the high-voltage cable is laid, in order to make it a continuous Lines, each section of the line must be connected as a whole, so the cables need to be lapped. Before the cables are lapped, the insulation protection sheet at the corresponding position of the original cable will be removed, so that part of the cable is exposed and locked through the cable lap joint. Lap joints are used to prevent the cables from being exposed. The existing cable lap joints are only suitable for cables of this specification due to their fixed specifications. The aging of high-voltage cables is prone to leakage, even explosion and fire

Abstract

The invention discloses a cable lap joint device. The device structurally comprises a first cable, a lapping device and a second cable, the first cable is connected with the second cable; the lappingdevice is arranged at the joint of the first cable and the second cable, and connected with the first cable and the second cable. Compared with the prior art, the cable lap joint device has the advantages that a first sealing and fastening mechanism, a first mounting mechanism, a damp-proof sleeve, a second mounting mechanism and a second sealing and fastening mechanism are arranged in a combinedmode; the device is suitable for cables of different specifications, is wide in application range, can comprehensively protect the lap joint of the cables, prevents the cables from being affected withdamp and short-circuited, reduces aging of the cables, avoids electric leakage caused by faults of the cables, and prevents the cables from exploding and catching fire.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to a cable lap. Background technique [0002] The cable is the bridge between the power supply equipment and the electrical equipment, which plays the role of transmitting electric energy, and the high-voltage cable is a kind of power cable, which is mostly used in power transmission and distribution. After the high-voltage cable is laid, in order to make it a continuous Lines, each section of the line must be connected as a whole, so the cables need to be lapped. Before the cables are lapped, the insulation protection sheet at the corresponding position of the original cable will be removed, so that part of the cable is exposed and locked through the cable lap joint. Lap joints are used to prevent the cables from being exposed. The existing cable lap joints can only be used for cables of this specification due to their fixed specifications. The scope of application is narrow, ...
