Environment-friendly high-performance automatic constant temperature cable

Abstract

The invention discloses an environment-friendly high-performance automatic constant temperature cable. The cable comprises a constant temperature cable unit, a heat preservation unit and a protective sleeve unit. The heat preservation unit is wound around the outer surface of the constant temperature cable unit in a wrapping mode, and the protective sleeve unit is wound around the surface of the side, away from the constant temperature cable unit, of the heat preservation unit in a wrapping mode. A constant power tracing ribbon is arranged beside a cable core of the cable, after the constant power tracing ribbon is powered on, a nichrome heating element in the constant power tracing ribbon carries out heating, therefore, the interior of the cable can be kept at a constant temperature, the overall temperature of the cable is not too low, ice and snow outside the cable can be melted, the phenomenon that a cable jacket is directly cracked due to the fact that the environmental temperature is too low can be avoided, effectiveness is achieved, the cable has longer service life, the high performance of the cable can be better maintained, electric energy losses generated when the constant power tracking ribbon works are well reduced, and resources are saved.

Description

technical field [0001] The invention relates to the technical field of environment-friendly cables, in particular to an environment-friendly high-performance automatic constant temperature cable. Background technique [0002] Cables are usually twisted by several or several groups of wires, similar to ropes, each group of wires is insulated from each other, and is often twisted around a center, and the entire outside is covered with a highly insulating coating. The cable has the characteristics of internal electrification and external insulation. [0003] In the prior art, due to the factors of the installation environment, many cables are installed outdoors. When encountering cold weather, the surface is easily covered with snow and ice, so the following two problems are very likely to occur: 1. When the weight of ice and snow exceeds the performance of the cable jacket After the bearing capacity, it is easy to cause the cable to pull down the transmission tower or the uti...

Problems solved by technology

[0003] In the prior art, due to the factors of the installation environment, many cables are installed outdoors. When encountering cold weather, the surface is easily covered with snow and ice, so the following two problems are very likely to occur: 1. When the weight of ice and snow exceeds the performance of the cable jacket After the bearing capacity, it is easy to cause the cable to pull down the transmission tower or the utility pole; 2. The cable of ordinary material is easy to crack at low temperature, which directly affects the service life and performance of the cable
