Abstract

The invention relates to a high-voltage power cable tension clamp. The high-voltage power cable tension clamp comprises an insulation disk, insulation supporting rods, built-in ground clamps, a shielded wire ground clamp and a ground clamp. One end of each insulation supporting rod is fixed to the insulation disk, a cavity is formed inside each insulation supporting rod, a cable is sleeved with each insulation supporting rod, and one end of each built-in ground clamp stretches into the corresponding insulation supporting rod and is connected with the corresponding cable. One end of the shielded wire ground clamp and one end of the ground clamp are connected with a shielded wire and a combined core cable through the insulation disk. All ends of the three-core cable are fixed through the high-voltage power cable tension clamp, all the ends are grounded firmly and reliably, and inspection and acceptance proceed smoothly. Meanwhile, the high-voltage power cable tension clamp is simple in structure, high in practicality, safe, reliable, and high in application and popularization value.

Description

technical field [0001] The invention relates to an auxiliary tool for a power system, in particular to a tension clamp for a high-voltage power cable, which is mainly used in places such as the acceptance test of a three-core cable, where it is necessary to separate the heads of the cables. Background technique [0002] The three-core cable is made by twisting three single-core cables, wrapping them, and extruding the sheath. It has the advantages of being able to withstand mild physical impact and pressure, and not easy to be damaged. It is now widely used in power systems, such as 220kV and 66kV outgoing lines, 10 kV switching stations, 10 kV box-type substations, etc. [0003] However, when carrying out the acceptance test of three-core cables, it is often encountered that the work site is messy and disorderly, and the equipment to be accepted and the test instrument occupy the space of each other, so that the test cannot be carried out smoothly. At the same time, due t...
