A large-length high-voltage cable clamping head and its assembly method

Abstract

The invention discloses a large-length high-voltage cable clamping head and an assembly method thereof, comprising a first cable, a first clamping head, a second clamping head and a second cable, one end of the first cable is fixedly connected to the first The left side of the clamping head, the right side of the first clamping head are fixedly connected to the left side of the second clamping head, and the right side of the second clamping head is fixedly connected to one end of the second cable. In the large-length high-voltage cable clamping head and its assembly method, the exposed metal wire part is inserted into the first sleeve and the end of the second sleeve provided with a tapered block, and the second bolt is tightened to make the clips close to each other to clamp the first cable. Metal wire, then tighten the first bolt to deform the clamping ring, and clamp the exposed metal wire of the first cable. Finally, by tightening the helical gear head, the gear drives the rack to move, thereby pushing the push ring to move. In the role of the connecting rod The lower drives the tapered block to move in the tapered groove, which can effectively achieve fast installation of the first cable and the second cable and the first chucking head and the second chucking head.

Description

technical field [0001] The invention relates to the technical field of high-voltage cable assembly, in particular to a large-length high-voltage cable clamping head and an assembly method thereof. Background technique [0002] At present, domestic and foreign cable manufacturers mostly adopt segmental production and delivery methods when producing high-voltage land power cables. Since the outer diameter of high-voltage land power cables is usually above 100mm, the delivery length of a single finished product is generally 300-600m. , the main reason for determining the length of delivery is due to the strict restrictions on the load and the height of the plate due to road transportation. The delivery length of high-voltage land power cables determines the number of intermediate joints on the line. Many institutions at home and abroad have made statistics on the fault conditions of power lines, and the results obtained all show that the intermediate joint is the weakest link o...

Problems solved by technology

[0003] In the past, the traditional length of high-voltage cables could not adapt to the packaging and delivery of high-voltage terrestrial power cables with a length of more than 1km in the way of reeling, use of reels, and packaging methods. Therefore, an intermediate joint was continued to be designed to change the current problem.
