Abstract

The invention discloses a light-reducing type power cable protection tube, belonging to the field of power cables, and a light-reducing type power cable protection tube. The solution can realize that when the protection tube is corroded by external heat, the heat will be first introduced into the air bag. The cooling liquid inside cools the introduced heat, and when the temperature is too high, it can be absorbed by the graphene layer first, and the absorbed heat is introduced into the memory spring through the fixed plate, and then the memory spring is deformed. When stretched open, heat will be introduced to the rubber bladder, and the ammonium chloride powder will expand when the rubber bladder is heated, which will fill the space between the fixed plate and the heat insulation The airbag is first squeezed to initially relieve the impact force, and then the impact force will be transmitted to the fixed plate, and the rubber bag will shock it for a second time, so as to achieve the cooling effect of external impact objects while dissipating heat. stress relief.

Description

technical field [0001] The invention relates to the field of power cables, in particular to a light-reduction type power cable protection tube. Background technique [0002] Power cables are cables used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, power station lead lines, internal power supply in industrial and mining enterprises, and underwater transmission lines across rivers and seas. In power lines, the proportion of cables is gradually increasing. Power cables are cable products used to transmit and distribute high-power electric energy in the backbone lines of power systems, including 1-500KV and above various voltage levels, various insulated power cables, and cable protection tubes are used to prevent cables from being damaged. , laying on the outer layer of the cable, a metal protection tube with a certain mechanical strength, the cable protection tube is mainly installed at the intersection of the commun...
