Cables are commonly used conductors in people's daily life. At present, with the continuous development of social economy, the using amount of the cable is rapidly increased, and the quality requirement of the cable is continuously improved. In recent years, the importance of water resistance of cables laid in harsh and humid environments has become increasingly recognized.
The cable laid under water or underground is easy to have insulation damage, insulation aging deterioration, mechanical damage, wire core loosening and other situations due to factors such as moisture absorption, external force extrusion and the like. During the laying process, the cable is highly likely to be subjected to soil pressure and external force damage due to human factors, and water enters from the damaged part or the joint part and then diffuses to the two ends of the cable, so that the electrical performance of the cable is reduced. In addition, in the process of storage, transportation, laying and operation of the cable, the cable protective layer is damaged due to the accidental action of mechanical force, water enters from the damaged part to the inside and then diffuses towards the two ends of the cable, so that the electrical property of the cable is reduced, and the service life of the cable is shortened.
