1. In order to ensure waterproof and long-term operation, it is recommended to use double-wall heat shrink tubing and insulating tubing.
2. In order to ensure that the joint can withstand a certain pressure, it is recommended to add a sheath to enhance insulation and protection.
3. The self-adhesive tape (or heat shrinkable waterproof tape) used is a high-voltage product to ensure insulation safety.
4. When constructing, it is best to use the staggered connection method (that is, the cable does not need to be neatly cut and butted).
