Abstract

The invention discloses a cable construction tightening device for a high-voltage power grid, relates to the technical field of cable take-up, and provides the following scheme for solving the problems that an existing cable connection box is not provided with a heat dissipation structure, the internal temperature is too high, consequently, the use safety is low, the take-up function is not achieved, a cable is loosened in use, and the connection stability is low: the cable construction tightening device comprises a box body, a fixing rod is welded to the inner wall of the box body, a conductive sleeve is welded to the other end of the fixing rod, a conductive column is arranged in the conductive sleeve in a penetrating mode, fixing blocks are fixedly connected to the two ends of the conductive column, and a cable body is fixedly connected to one side of each fixing block. The cable construction tightening device is simple and novel in structure, tightens a cable during installation, prevents the cable from loosening to affect the stability of electric power connection, improves the use safety of the cable, determines the position of the cable through the positioning bolt during rotary take-up, prevents the take-up reel from rotating reversely, improves the take-up stability, has the ventilation and heat dissipation effects, improves the use effect, and is suitable for popularization.

Description

Technical field[0001]The invention relates to the technical field of cable take-up, in particular to a cable construction tightening device for high-voltage power grids.Background technique[0002]Cable is a general term for optical cables and cables. There are many uses for cables, which are mainly used for multiple functions such as controlling installation, connecting equipment, and transmitting power. It is a common and indispensable thing in daily life. As the cables are live, the installation requires special care. The transmission of electric energy, together with power transformation, distribution and electricity consumption, constitute the overall function of the power system. Through power transmission, power plants and load centers that are far apart (up to thousands of kilometers) are connected, so that the development and utilization of electric energy exceeds geographical restrictions. Transmission lines can be divided into overhead transmission lines and underground tra...
