Description

TECHNICAL FIELD

[0001] The utility model relates to the cable protection pipe field more specifically, relate to a kind of high-strength composite power cable protection pipe. BACKGROUND

[0002] Power cable protection pipe refers to the pipe or sleeve laid on the outer layer of power cable to prevent damage, with certain mechanical strength and protective performance. Power cable protection pipe can protect the cable from mechanical pressure, chemicals, moisture, corrosion and electromagnetic interference, thereby prolonging the service life of the cable and ensuring the safety and stability of power transmission.

[0003] In traditional power cable protection pipe, multiple cables are simply placed in the same space without effective separation. This leads to mutual compression between cables when the number of cables is large or the specifications are different, which not only affects the heat dissipation and performance of the cables, but also may cause damage to the cable insulation layer, increasing the risk of failure. Cable compression may cause signal interference, insulation performance degradation, and even safety problems such as short circuit. Some power cable protection pipes have simple structure and insufficient connection strength, which leads to deformation or rupture of the protection pipe under external force, affecting the protection effect of the protection pipe on the cable.
