Abstract

The invention discloses a high-temperature and high-voltage power cable which comprises a conductor, an insulation layer, a wrapping tape layer, an inner protection sleeve, an armor layer and an outer protection sleeve, wherein the insulation layer is wrapped outside the conductor to form an insulation cable core, the wrapping tape layer is wrapped outside the insulation cable core, the inner protection sleeve is wrapped outside of the wrapping tape layer, the armor layer is wrapped outside the inner protection sleeve, and the outer protection sleeve is wrapped outside the armor layer. The insulation layer is made of water-resistant tree irradiation cross linked polyethylene material. The inner protection sleeve and the outer protection sleeve are made of thermoplasticity elastic material. Therefore, in a high-voltage transmission process under high temperature, occurrences of degradation and damage of the cross linked polyethylene insulation layer caused by aging of electric branches or other reasons are reduced, stability and reliability of working of the cross linked polyethylene insulation power cable are improved, and the service life of the cable is prolonged.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a high-temperature and high-voltage power cable. Background technique [0002] XLPE insulated power cables are widely used in the field of high-voltage and extra-high-voltage cables due to their good electrical properties, large transmission capacity, light weight, high drop or vertical laying, installation and maintenance, etc. In the practical application of XLPE insulated power cables, the XLPE insulation layer is easily deteriorated and destroyed due to the aging of electric branches; drop, there is a potential safety hazard of cable breakdown. [0003] Therefore, how to improve the structure of the cross-linked polyethylene insulated power cable in the prior art, in order to reduce the damage caused by the aging of the cross-linked polyethylene insulation layer to the power cable when high-voltage transmission is carried out in a high-temperature working environment, and imp...
