Introduction to the "Insulation Repair" Method for Power Cables


The Power Cables is very Considerable in China. 

The production of power cables is cumbersome. 

If the production time is too long, it is easy to cause failures. It is necessary to insulate and repair. The country also has relevant regulations on this issue.


The general conventional repair method is to use the welding gun heating repair method, which is simple, convenient and practical, and the effect is also ok. However, if the repaired place is used for a long time, the insulation will shrink, the underground cable will not be able to prevent moisture and water, and the atrophy of the overhead power cable will be extended.


Another Method is the Middle of the Cable. 

This method is very effective in protecting the cable insulation. 

The structure of the product is mainly: 

The entire cable damage is covered, and the cable can be quickly wrapped by heat treatment or cold treatment. 

The ideal effect of the original cable is consistent. 

However, the material for repairing the power cable is more expensive than the ordinary repair method.

But the effect is very good. Especially when the cable is laid, the cable is damaged to take the repair method.


The repair method of the power cable is probably the two types. 

Of course, there are temporary insulation tapes on the site that can be maintained, but it is only a temporary emergency. 

In the original production process, the relevant national standards stipulate that the insulation layer cannot be repaired without the written consent of the user. Power cable outer insulation repair has advantages and disadvantages, of course, it is certainly not the original factory production is not repaired.
