Embodiment 1

[0032] Such as figure 1 As shown, the four-layer aluminum wire steel-cored aluminum stranded wire is a large-section wire. This large-section wire 1 includes a steel core 2, and the steel core 2 is covered with an inner layer of aluminum wire 3 from the inside to the outside. Layer aluminum wire 4, adjacent outer layer aluminum wire 5 and outer layer aluminum wire 6.

[0033] Such as image 3 As shown, the splicing pipe for large-section wires described in this example is used to join two large-section wires 1 to transmit mechanical and electrical loads. The splicing pipe includes aluminum pipe 7, steel pipe 8 and two aluminum liner pipes 9 , the steel cores 2 of the two large-section conductors 1 extend into the steel tube 8 from the two ends of the steel tube 8 respectively, and the steel tube 8 is crimped to the two sections of the steel core 2 that are placed in the overlapping shape, and the two aluminum liners 9 are respectively sleeved on the adjacent inner layer alum...

Embodiment 2

[0042] The structure and connection method of the connecting pipe described in this example are basically the same as those in Example 1, except that:

[0043] The splicing tube includes an aluminum tube 7, a steel tube 8 and an aluminum liner 9. The aluminum liner 9 is simultaneously sleeved on the adjacent outer layer aluminum wires 4 of the two conductors and the steel tube 8 for crimping the steel cores of the two conductors. Above, the length of the aluminum liner 9 is the sum of 3-4 times the outer diameter of the wire and the length of the steel pipe 8 .

Abstract

The invention provides a hydraulic connecting tube, comprising a connecting tube aluminum tube, a connecting tube steel tube and an aluminum liner tube, wherein, the connecting tube aluminum tube 7 is an extrusion aluminum tube, and the end is provided with a bevel; the end of the connecting tube steel tube is provided with an inverted circular angle; the connecting tube steel tube is used for inserting steel cores of two large-section conducting wires into the tube, leads the two steel cores to be lapped with each other, and compresses the two steel cores, the aluminum liner tube replaces a certain length of an adjacent-outer-layer of aluminum wire and an outer layer of aluminum wire of the two large-section conducting wires, and the connecting tube aluminium tube is compressed on the outer layer of aluminum wire and the aluminum liner tube. The connecting tube provided by the invention removes a certain length of the adjacent-outer-layer of aluminum wire and the outer layer of aluminum wire, and uses the aluminum tube with the same internal diameter and the external diameter to replace and fill the wire; when the aluminum tube is connected, the connecting tube aluminum tube is compressed to the filling aluminum tube and the outer layer of aluminum wire, the compression is ensured safe and reliable, meanwhile, the efficiency and stability of the conducting wire holding for the connecting tube are ensured.

Description

Technical field [0001] The present invention involves a continuous pipe for a large -section wire, which is the field of connecting gold tools that connect the wire connection wires of overhead power delivery lines. Background technique [0002] The two terminals for the continuation of the wires for overhead transmission line circuit wires. In addition to being lifted by the entire wire, it is also used as a conductive conduction current, which is an important gold tool in the transmission line.The wire is one of the most important components of the transmission line. Due to the existence of the wire resistance, the power energy will generate certain losses during transmission. This part of the electric energy loss is often overlooked. In fact, this part of the loss is considerable. Therefore, appropriate, appropriate, appropriateGround increased wire section to effectively reduce the wire loss of the transmission line, which is also the key to the energy conservation and consum...
