An insulated high voltage power cable

Abstract

The invention relates to the technical field of high-voltage power cables, in particular to an insulated high-voltage power cable, comprising a cable conductor and a protective multi-layer jacket. A plurality of ring groove groups are opened in the insulating tube. The ring groove group includes three installation grooves, and arc blocks are connected in the three installation grooves. A rotating push rod is connected between the arc blocks and the installation grooves. There are two through-bar holes, and six round holes are opened on the shielding insulating tube. The round holes are connected with steel wire ropes. The ring is connected with the steel wire rope, the reset spring is connected with the shielding insulating tube, and the shielding insulating tube is connected with a positioning mechanism and three sets of power mechanisms through the end frame. The maintenance and replacement of the conductor is easier and the operation is more convenient.

Description

technical field [0001] The invention relates to the technical field of high-voltage power cables, in particular to an insulated high-voltage power cable. Background technique [0002] As we all know, the insulated high-voltage power cable is an auxiliary device for power transmission and distribution during the use of high-voltage power, and it has been widely used in the field of high-voltage power consumption technology. [0003] The existing underground high-voltage power cable includes a cable conductor and an outer protective sheath, the cable conductor is arranged inside the outer protective sheath, and a number of steel wire ropes are arranged in the outer protective sheath. When in use, the underground high-voltage power cable is buried underground, and the underground Both ends of the high-voltage power cable are communicated with the outside world, so as to realize the transmission and distribution of high-voltage power. [0004] However, the above-mentioned prior...

AI Technical Summary

Problems solved by technology

[0004] However, the following defects still exist in the above-mentioned prior art solutions, the laying process of the underground high-voltage power cable is easier to scratch the outer protective cover, the protection effect is poor in the installation process, and it is easier to reduce the insulation effect of the underground high-voltage power cable, It has a certain impact on the service life of underground high-voltage power cables. At the same time, during the use of underground high-voltage power cables, it is difficult to maintain and replace them, and the operation convenience is poor.
