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 which comprises a cable conductor and a protective multi-layer sleeve, the cable conductor is arranged in the protective multi-layer sleeve, the protective multi-layer sleeve is sleeved with a shielding insulating tube, a plurality of ring groove sets are formed in the shielding insulating tube, and each ring groove set comprises three mounting grooves. Arc-shaped blocks are connected in the three mounting grooves, rotating push rods are connected between the arc-shaped blocks and the mounting grooves, two through strip holes are formed in each arc-shaped block, six round holes are formed in the shielding insulating tube, steel wire ropes are connected in the round holes, the steel wire ropes penetrate through the through strip holes, the steel wire ropes are sleeved with a plurality of reset springs, and the reset springs are connected with baffle rings. The baffle rings are connected with the steel wire ropes, the reset springs are connected with the shielding insulating tube, and the shielding insulating tube is connected with a positioning mechanism and three groups of power mechanisms through the end frame, so that in the laying process, the protection performance is relatively good, the bearing tension is relatively good, the service life is relatively long, the maintenance and replacement of the cable conductor are relatively easy, and the operation is relatively convenient.

Description

Technical field[0001]The present invention relates to the technical field of high voltage power cables, and is specifically an insulating high voltage power cable.Background technique[0002]It is well known that insulated high voltage power cables are an auxiliary devices for power transmission and distribution during high voltage power, which are widely used in high-pressure electricity technology.[0003]The existing underground high voltage power cable includes a cable conductor and an outer protective cover, and the cable conductor is disposed inside the outer protective cover. There are several wire rope in the outer protective sleeve. It is buried underground high-voltage power cable in the use of the underground. The two ends of the high voltage power cable communicate with the outside, thereby realizing the transmission and distribution of high voltage power.[0004]However, in the prior art plan, there is still the following defects, and the laying process of the underground hig...

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.
