Problems solved by technology

For this reason, if the design uses ordinary wires, it is necessary to increase the cross-section of the wires and increase the number of split wires, which will inevitably increase the use of wires and busbars, the structural size of the iron tower and the width of the line corridor, etc., thus increasing the engineering cost. invest

Embodiment 1

[0024] The invention provides a splicing tube for supporting type expanding wires, its function is to join two supporting type expanding wires to transmit mechanical and electrical loads, such as figure 1 As shown, the supporting expanded-diameter conductor 1 includes a steel core 1 , and the steel core is covered with a support layer 3 , an inner layer aluminum wire 4 and an outer layer aluminum wire 5 sequentially from the inside to the outside.

[0025] Such as figure 2 As shown, the connecting pipe described in this example includes aluminum pipe 7, steel pipe 8 and aluminum lining pipe 6, and the wires 1 extend into the aluminum pipe 7 from both ends of the aluminum pipe 7 respectively, and the heads of the two wires 1 are overlapped. Together, the heads of the two overlapped wires are crimped through the steel pipe 8 arranged in the aluminum tube 7. The aluminum tube 7 is provided with two aluminum liners 6, and the two aluminum liners are respectively socketed On the ...

Embodiment 2

[0033] The structure and connection method of the connecting pipe described in this example are basically the same as those in Example 1, except that:

[0034] An aluminum liner 6 is arranged inside the aluminum tube 7, and the aluminum liner is sleeved on the steel core 2 of the two wires and the steel pipe 8 for crimping the heads of the two wires at the same time. The length of the aluminum liner 6 is the length of the wire The sum of 6.5-7 times of the outer diameter and the length of the steel pipe 8.

Abstract

The invention provides a splicing tube for a support-type expanding wire, which includes an aluminum tube 7, a steel tube 8 and an aluminum lining tube 6. The aluminum tube 7 is an extruded aluminum tube with a bevel at its end; the end of the steel tube 8 The head is rounded; the steel pipe 8 is used to insert the steel core 2 of the two supporting type expanded diameter wires into the pipe, and make the two steel cores 2 overlap, and then crimp them, and the aluminum liner 6 replaces them The high-density polyethylene support layer 3 and the aluminum tube 7 are crimped on the outer layer aluminum wire 5 and the aluminum liner 6 for a part of the length of the two support type expanded diameter wires. The splicing pipe of the present invention is suitable for supporting type expanding wires, can stably and effectively hold the supporting type wires, has simple structure and stable and reliable construction process.

Description

technical field [0001] The invention relates in particular to a matching splicing pipe for a support-type enlarged-diameter wire, which belongs to the field of connecting fittings for connecting two terminals of a wire for an overhead power transmission line. Background technique [0002] The wire splicing tube is used for the two terminals of the overhead transmission line wire. In addition to bearing all the tension of the wire, it also conducts current as a conductor and is an important fitting in the transmission line. The UHV project aims to build an "environmentally friendly" project, comprehensively optimizes the design of the project, and strictly ensures that the electric field, magnetic field, audible noise and radio interference levels meet the standard requirements. For this reason, if the design uses ordinary wires, it is necessary to increase the cross-section of the wires and increase the number of split wires, which will inevitably increase the use of wires a...
