HJVV communication cableUsed for connecting between distribution frames and switches or between various levels of machines within switches (including those used in rural areas), as well as the starting and ending points of lines, for connecting local cables to distribution boxes or distribution frames,

The 6 major usage precautions are as follows:

1. The ambient temperature during cable laying and installation shall not be lower than -5 ℃;

2. The minimum bending radius during cable laying should not be less than 15 times the outer diameter of the cable;

3. Cable reels are only allowed to roll in one direction for short distances and are not allowed to be laid flat;

4. When the cable enters the pipeline, attention should be paid to reducing the friction between the cable and the pipe wall. When the cable enters the manhole, the bending radius should not be less than the radius of the cable reel, and friction with the edge of the hole should be avoided.

5. During cable operation, a certain pressure of dry gas should be filled (30-50kPa of dry air has been stored before leaving the factory)

6. The working environment temperature of the cable is -30 ℃ to+60 ℃
