Description

Technical Field

[0001] This utility model relates to the field of high-voltage cable technology, and in particular to a durable and long-life high-voltage cable. Background Technology

[0002] High-voltage cables are a type of power cable, mainly used to transmit power between 1kV and 1000kV, and are widely used in power transmission and distribution.

[0003] However, it still has the following drawbacks in practical use:

[0004] Existing high-voltage and ultra-high-voltage cables have an asphalt anti-corrosion layer. When the fire is large, the asphalt will vaporize when heated, and the pressure generated will break through the residue after the outer sheath is burned, and start burning directly. This not only poses a safety hazard, but also directly causes the high-voltage cable to be scrapped, increasing costs. Utility Model Content

[0005] The purpose of this utility model is to provide a durable and long-life high-voltage cable to solve the problem mentioned in the background art that existing high-voltage and ultra-high-voltage cables have an asphalt anti-corrosion layer.

[0011] Furthermore, a conductor is fixedly connected inside the insulating sleeve.

[0012] Furthermore, a connecting groove is provided on the inner side of the slot, and the size of the swivel ring is adapted to the size of the connecting groove.

[0013] Furthermore, the flame-retardant sleeve is made of flame-retardant polyethylene sheath material, and the inner side of the flame-retardant sleeve is provided with water-blocking filler.
