High flexible cable waterproof joint is a connecting device with high safety and reliability and can be used in water. Its biggest feature is that it can play a waterproof effect. It is mainly used in power system, and it also plays a role in some outdoor products we use every day. So what are the precautions for the installation and use of high flexible cable waterproof joints? Now let's go and have a look!

First of all, the selection of appropriate joint materials should be carried out according to the model and specification of the cable joint itself. Because there are a wide range of cable joints in the market and their quality is uneven, in order to ensure their quality and safety performance, it is best to select some manufacturers with higher reputation and better product quality for joint purchase.

In addition, when making joints, avoid some humid environment and try not to do it in rainy days. Once a certain amount of water is poured into the cable joint, it is likely to cause short circuit, which will seriously reduce its service life. Of course, it is best to carefully read the manufacturer's product instructions before manufacturing. It is best to plan all manufacturing processes and make a detailed list before manufacturing, which has a great impact on cables higher than 10kV. In addition, when pressing the copper pipe, just crimp it in place. Do not use brute force. After crimping, usually use a file to flatten the convex starting point on the surface of the copper end, so as to avoid the remaining burrs from hurting the users.

Secondly, heat shrinkable and cold shrinkable cable joints also have different requirements. Generally, the former shall move back and forth in multiple directions when applying the blowtorch, and the size of the latter shall also be in strict accordance with the drawing.

Finally, in order to ensure that the joint has higher waterproof capacity and longer operation time, it is best to use double wall glue for insulation and heat shrinkable sleeve, and in order to ensure that it can withstand a certain pressure, it is best to strengthen its protection and insulation, which can generally be carried out by adding protective sleeve. And it is best to stagger the cable joints.

In conclusion, there are many precautions in the installation and use of high flexible cable waterproof joints. Therefore, it is better for both construction personnel and users to carefully read the factory manual, and put forward problems they do not understand in the process of reading, so as to solve them in time, so as to avoid dangers to a certain extent.
