1. Select the appropriate connector materials according to the model and specification of the cable connector required. Nowadays, the quality of the cable connector materials is also uneven. However, in order to ensure the quality of the cable connector, it is recommended not to be greedy for cheapness. It is better to choose the materials from the cable connector manufacturers with reliable quality.

2. It is better not to choose rainy days when connecting cables, because the service life of cables will be seriously affected by the water in cables, and even short circuit accidents will occur.

3. Before making the cable waterproof joint, it is necessary to carefully read the manufacturer's product manual, which is particularly important for 10kV and above cables. Before doing all the procedures, think well and then do them.

4. For the terminal joint of single core armored cable above 10kV, remember that only one end of steel strip can be grounded.

5. The copper tube should not be pressed too hard. As long as it is pressed in place, there will be many protruding points on the copper end face after crimping. This must be flattened with a file without any burr.

6. When using the heat shrinkable cable connector, pay attention to the back and forth movement of the blowtorch, instead of continuous blowtorch in one direction.

7. The size of the cold shrink cable joint must be strictly in accordance with the drawing instructions, especially when pulling out the support in the reserved pipe, more attention should be paid.
