Problems solved by technology
[0005] The wind in Xinjiang is relatively strong, and cables with sag, especially cables without insulation (bare wires) or cables with damaged insulation are prone to phase-to-phase short circuit after dancing. During this period, a lot of maintenance workload has been increased, and safety hazards have also been increased.

[0038] Such as Figure 1~6 As shown, it shows a specific embodiment of the present invention. As shown in the figure, the portable power transmission cable fixing device of the present invention, the power transmission line is erected through utility poles, and the utility poles are multiple groups arranged along the extension direction of the power transmission line. Two adjacent groups of poles are one file; it includes a fixed unit erected on the cables of each file; the fixed unit can be used in each file, and can also be selectively used in different files. Generally, the choice is affected by the wind On the cable with the larger sag and the more severe galloping;
[0039] The fixing unit includes an insulating cross arm 1, on which at least two clamping assemblies 2 for clamping cables are arranged, and at least one screw sleeve for assembling an insulating rod 4 is also included on the insulating cross arm 1 Component 3; the insulating rod 4 is assembled on the screw ...

Description
technical field [0001] The invention relates to an auxiliary tool for power transmission cables, which is specifically used for fixing power transmission cables with a voltage level of 10kV and below. Background technique [0002] Transmission cables are used to transmit electric energy. There is a level between adjacent utility poles. The transmission line of each level has a certain sag, especially when the power system transmission line conductor is very long, sag will occur. When there is a big wind and rain, there will be a large gallop, which may lead to collision between the wires and a phase-to-phase short circuit, which seriously affects the safe and stable operation of the power system. [0003] In the high-voltage line, especially the transmission cables above 10kV, in order to prevent the phase-to-phase short circuit caused by galloping, the insulator structure is adopted, and the split conductors of higher voltage levels are also designed with a special fixed-di...
