1. In the normal operation of Guangxi cable, if there is a breakdown other fault for some reason, the water in the cable trench will enter the cable along the fault point; in civil construction, especially in the construction site large construction machinery is used, It is uncommon for cable damage failure accidents caused by various human factors. When such an accident occurs, the cable insulation can be severely damaged water can enter the cable.Guangxi cable manufacturer

2. After the cable is laid, due to the on-site construction conditions, the cable head cannot be made in time, so that the unsealed cable fracture is exposed to the air for a long time, even immersed in water, resulting in a large amount of accumulated water vapor entering the cable.

3. When the new cable leaves the factory, both ends of the cable are sealed with plastic sealing sleeves, but after a period of use, according to the actual situation of the construction site, simply wrap the rest of the cable with plastic cloth. If the sealing is good, it will inevitably become Causes moisture to penetrate into the cable.

4. In the process of making the cable head (including the terminal head the intermediate joint), due to the negligence of the construction personnel, the newly processed cable head may accidentally fall into the stagnant water on site.Guangxi wire cable

5. When laying cables, it is often necessary to cross roads, bridges culverts. Due to weather other reasons, water often accumulates in Guangxi wire cable trenches. During the laying process, the cable head will inevitably be immersed in water. Water enters the cable due to loose damaged plastic packaging; in addition, when pulling, puncturing the pipe, it sometimes scratches the outer sheath even the steel armor. This phenomenon is particularly prominent when mechanical traction is used.Guangxi cable.
