Embodiment Construction

[0032] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] This embodiment takes the connecting pipe as an example, such as Figure 1 to Figure 5 As shown, the connecting pipe provided by the embodiment of the present invention includes: connecting pipe 1 , crimping pipe 2 , sleeve 3 , aluminum alloy core 4 , and aluminum profile wire 5 .

[0034] Strip the aluminum alloy wire 5 at the two terminals of the aluminum alloy core aluminum wire conductor, expose the aluminum alloy core 4 and put it into the crimping tube 2, and the crimping tube 2 is set in the middle of the connecting tube 1; Sleeve 3 is arranged symmetrically between the end and the gap between the aluminum alloy cored aluminum type wire, and finally the connecting tube 1, crimped tube 2, sleeve 3 and the aluminum alloy cored aluminum type wire are compressed into a hydraulic crimping method. One body, afte...

Abstract

The invention provides a splicing tube which is used for splicing the connectors of two wires arranged in the splicing tube. The splicing tube is characterized in that a press connecting tube 2 is arranged on the connectors of the wires; sleeve tubes 3 are arranged at the two ends of a splicing tube body 1 and located between the clearances of the splicing tube body 1 and the wires; the splicing tube body 1, the press connecting tube 2, the sleeve tubes 3 and the wires are coaxial. Compared with the prior art, the splicing tube adopts hydraulic press connection, the process is mature, the press connecting quality is easy to guarantee, the press connection problem of aluminum alloy core aluminum molded line wires is solved, the clearances between the aluminum alloy core aluminum molded line wires and the splicing tube are filled, and effective and stable holding to the aluminum alloy core aluminum molded line wires by the splicing tube is ensured; aluminum tubes are used, tension force between the aluminum alloy core aluminum molded line wires can be effectively borne, and the aluminum tubes can be used as the good conduction currents of electric conductors.

Description

technical field [0001] The invention relates to a splicing pipe, in particular to a connecting fitting for connecting two terminals of an overhead power transmission line. Background technique [0002] Power transmission is achieved by using a transformer to boost the power generated by the generator, and then connecting it to the transmission line through circuit breakers and other control equipment. According to the structural form, transmission lines are divided into overhead transmission lines and cable lines. The overhead transmission line is composed of line towers, wires, insulators, line fittings, guy wires, tower foundations, grounding devices, etc., and is erected above the ground. According to the nature of the transmission current, power transmission is divided into AC transmission and DC transmission. In the 1880s, DC transmission was first successfully realized. However, because the voltage of DC transmission was difficult to continue to increase under the t...
