Abstract

The invention discloses a cold-resistant power cable. The cold-resistant power cable comprises a plurality of cable cores (4); each cable core (4) comprises a conductor (1); an insulating layer (2) is arranged on the conductor (1) in an extruding manner; the space among the cable cores (4) is filled with a packing layer (3); the external of the cable core (4) is wrapped with a belting layer (5); and the external of the belting layer (5) is wrapped with an outer sheath (6) in an extruding manner. The cold-resistant power cable is effective in the cold-resistant performance and capable of solving the problem of cracked power cables at low temperatures for providing guarantee for project constructions or project operations.

Description

technical field [0001] The invention belongs to the field of special cables and relates to a 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 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 cold-proof power cable for the defect of poor cold-proof effect of the power cable in the prior art. [0005] Technical solution: In order to solve the abo...
