Communication and power cable sleeve with high thermal conductivity, high pressure resistance and good strength

Abstract

The invention discloses a communication and power cable sleeve with high thermal conductivity, high pressure resistance and good strength. The communication and power cable sleeve comprises a sleeve body and a waterproof component, the sleeve body comprises a main pipe fitting, the inner side and the outer side of the main pipe fitting are respectively provided with a supporting structure and a reinforcing structure, the supporting structure comprises a stable cylinder core and a plurality of groups of supporting strips, and one sides of the supporting strips are uniformly arranged on the outer side of the stabilizing cylinder core. The invention relates to the technical field of power cables. According to the communication and power cable sleeve with high thermal conductivity, high pressure resistance and high strength, internal threads and external threads are spirally connected by rotating a rotating block, and the sleeve body and a waterproof component can be conveniently assembled and disassembled; and, in addition, a power cable is inserted into a cable port, a waterproof clamping plug is inserted into a first cable cavity and a second cable cavity, and the clamping grooves are clamped at the two ends of the stabilizing cylinder core and the supporting strip, so that the connection stability of the power cable sleeve body is further improved, and the problem that the service life of the power cable is affected due to water entering the sleeve can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to a communication and power cable casing with high thermal conductivity and high pressure resistance. Background technique [0002] With the continuous development of social economy and the increasing scale of construction, especially the rapid growth of urban infrastructure construction, environmental protection facilities and residential construction, many urban power cables are required to be grounded. [0003] At present, power cables in towns and industrial parks are mostly protected by hard polyvinyl chloride plastic sleeves. This material has good corrosion resistance, light weight, low cost, and simple installation. However, this power cable sleeve The main problem is that the power cable will generate heat during normal work, which will increase the temperature of the power cable. However, due to the poor thermal conductivity of the plastic sleeve, it is difficult to ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a communication and power cable casing with high thermal conductivity and high pressure resistance, which solves the problem of heat conduction of existing casings. The temperature of the power cable is poor, which will further increase the temperature of the power cable, reduce the current carrying capacity of the power cable, and affect the service life of the power cable, and the strength and toughness of the casing are small, the weather resistance is poor, and it is easy to break, which is easy to affect the overall project during the construction process. quality problem
