Abstract

The invention discloses a novel cold-proof power cable. The novel cold-proof power cable comprises a plurality of cable cores (1), wherein each cable core (1) comprises a conductor (1); an insulating layer (2) is extruded on each conductor (1); a space between the adjacent cable cores (4) is filled with a filling layer (3); a wrapping belt layer (5) is wound outside each cable core (1); an outer protective sleeve (6) is extruded outside each wrapping belt layer (5). The novel cold-proof power cable provided by the invention can be used for effectively preventing from coldness and the problem that the power cable is cracked at a low temperature is solved, so that guarantees are provided for engineering construction or operation.

Description

technical field [0001] The invention belongs to the field of special cables and relates to a novel cold-proof power cable. Background technique [0002] In the northern and western regions of my country, the low temperature lasts for a long time and the temperature difference between morning and evening is large. Especially in winter, the outdoor temperature in some parts of the northeast can reach minus 50°C. Ordinary cables will have cracks in the cable insulation and sheath during construction, laying or operation under these conditions, which is not conducive to the transmission of cable electric energy and reduces the service life of the cable. [0003] Therefore, a new type of cold-proof power cable is needed to solve the above problems. Contents of the invention [0004] Purpose of the invention: The present invention provides a new type of cold-proof power cable for the defect of poor cold-proof effect of the power cable in the prior art. [0005] Technical solut...
