Problems solved by technology

[0002] In order to improve the current-carrying capacity of power cables, large cross-sections are generally used, or the temperature during cable operation is increased, but due to the increase in temperature, the AC resistance of the conductor is directly increased, resulting in greater loss during transmission, and high temperature Running the cable under the environment will accelerate the aging of the cable insulation layer and sheath layer, reducing the service life of the cable

Abstract

The invention discloses a novel low-temperature cable which comprises an electric conductor. An electric conductor protection ring is arranged on the outer side of the electric conductor, a supportingframe is fixed to the outer side of the electric conductor protection ring, a heat preservation ring body is fixedly installed on the outer side of the supporting frame, a heat preservation layer isarranged on the outer side of the heat preservation ring body, and an outer armor layer is arranged on the outer side of the heat preservation layer. Compared with the prior art, the cable has the advantages that the sufficient supporting force can be provided for the internal cable, perfect protection and high-temperature heat transfer can be provided, the external low-temperature frost damage tothe cable can also be prevented, bidirectional protection is provided, the cable can still work normally in a low-temperature environment and under the condition that the external environment is severe, and the application market is wide.

Description

technical field [0001] The invention relates to the field of cables, in particular to a novel low-temperature cable. Background technique [0002] In order to improve the current-carrying capacity of power cables, large cross-sections are generally used, or the temperature during cable operation is increased, but due to the increase in temperature, the AC resistance of the conductor is directly increased, resulting in greater loss during transmission, and high temperature Running the cable under the environment will accelerate the aging of the cable insulation layer and sheath layer and reduce the service life of the cable. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a low-temperature cable for the above problems, which can increase the service life of the cable. [0004] In order to solve the above technical problems, the technical solution provided by the present invention is: a new type of low-temperature...
