The cable head is made of rubber material with good airtightness; in addition, the silicone grease filled between the cable head and the ceramic bottle of the ring network cabinet dries up after a long period of operation, making it difficult to manually remove the cable head. The method adopted in daily work is to use a rope to bind the cable head, and then forcefully pull the cable head out by 2 to 3 people.

The problems caused by removing the cable head by the existing method:

1. The stress point is located at the T-shaped corner of the cable head. During the pulling process, the rubber sleeve is easy to deform and cut the cable head.

2. Since the front plug of the cable is not fixed, the cable lug is easy to get stuck on the terminal of the ring network cabinet, which makes disassembly difficult; in addition, it is easy to damage the front plug of the cable and the porcelain bottle of the ring network cabinet by excessive force during the shaking of the cable, causing hidden dangers to the equipment.

3. The dismantling process is time-consuming and laborious, requiring 2 to 3 people. It takes up to 30 minutes to remove one phase.
