DPJ Standard31

It is mainly used in outdoor products, medium and large remote control machinery, and equipment whose main body is in the outdoor control system and not on the main body. For example, in chemical plants, power plants, power supply bureaus, base stations of telecommunication networks, and factories with a high degree of automation, cable waterproof connectors are all used.

Application note:

DPJ Standard11

In order to ensure waterproof and longer operation, it is recommended to use double-wall glued heat shrink tubing and insulating tubing.
In order to ensure that the joint can withstand a certain pressure, it is recommended to add a jacket tube to strengthen insulation and protection.
The self-adhesive tapes (or heat shrinkable waterproof tapes) used are all high-voltage products to ensure insulation safety.
During construction, the cable joints should preferably be staggered and connected (that is, the cables do not need to be neatly cut and connected).
