Problems solved by technology

[0003] In order to prevent the cable from being damaged, a cable protective sheath is usually provided on the outer surface of the cable, but the cable protective sheath in the prior art has a poor heat dissipation effect and cannot dissipate the heat on the surface of the cable in time, causing the cable to be easily damaged due to high temperature. Aging, damage, reducing the service life of the cable

Embodiment 1

[0037] see Figure 1-7 , a cable protective sleeve with a temperature regulating function, including a protective sleeve 101, a connecting hole 102 is opened in the middle of the protective sleeve 101, and a plurality of drop-shaped placement grooves 103 are installed inside the protective sleeve 101, and the protective sleeve The material of the barrel 101 is polyvinyl chloride, which has the advantages of flame retardancy, high chemical resistance, good mechanical strength and electrical insulation, so that the protective sleeve 101 can provide comprehensive and multifunctional protection for the cable, and the placement groove 103 The aluminum alloy is made of aluminum alloy, which has the advantages of light weight and high strength. When the temperature is high, the protective sleeve 101 will expand to a certain extent when heated. Squeeze to prevent the gap between the placement groove 103 and the heat shrinkable bag 201 from becoming smaller and affect heat dissipation....

Abstract

The invention discloses a cable protective sheath with a temperature regulating function, which belongs to the technical field of cable protective sheaths. A cable protective sheath with a temperature regulating function comprises a protective sleeve, a connecting hole is opened in the middle of the protective sleeve, and the protective sheath The inside of the cylinder is inlaid with a plurality of drop-shaped placement grooves, and each of the placement grooves is provided with connecting air holes on both sides. The connection holes are communicated, and a heat shrink bag matching with the placement groove is arranged inside each placement groove. It can realize the temperature adjustment that can imitate the skin. At high temperature, the heat shrinkable bag will automatically shrink, increasing the pores between the heat shrinkable bag and the support groove, thereby improving the heat dissipation efficiency. At the same time, the water in the water bag will be sprayed through the water outlet hole To the surface of the protective sleeve, the heat dissipation efficiency is further improved, thereby preventing the cable from being damaged by high temperature and improving the service life of the cable.

Description

technical field [0001] The invention relates to the technical field of cable protection sheaths, in particular to a cable protection sheath with a temperature regulating function. Background technique [0002] Power cables are cables used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, outgoing lines of power stations, internal power supply of 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 main line of the power system, including 1-500KV and above various voltage levels and various insulated power cables. Cable is an indispensable basic equipment for energy transmission and information transmission. Today, with the rapid development of social informatization and electrification, wire and cable have become one o...
