[0002] Insulating protective sleeve is an important protective material used to protect wires, cables, pipes and other equipment. The insulating protective sleeve is made of insulating material and can effectively prevent current from leaking from the wires. When the insulation layer of the wires is damaged, it may cause a short circuit between the wires or between the wires and other conductors. The insulating protective sleeve can provide an additional insulation layer to prevent this from happening.

[0003] During use, the existing insulating protective sleeve is used to seal and protect the wire pipe. In rainy weather, some rainwater will penetrate into the interior through the connection. When the insulating protective sleeve leaks water, the water will come into contact with the wires, causing the insulation performance of the wires to be greatly reduced. At the same time, it will also accelerate the aging of the wires and cause corrosion, and finally may cause serious electrical faults such as leakage and short circuit. Therefore, an insulating protective sleeve is proposed to solve the above problems. Utility Model Content
