In China, the production of power cables is very large, but the production process of power cables is very cumbersome. Not only is the production time long, but it is also prone to failure. In the event of a breakdown, insulation repairs are required, and there are regulations in the country regarding insulation repair problems.

In the event of a breakdown, insulation repairs are required, and there are regulations in the country regarding insulation repair problems.
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 (which the company sells). 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. Live, to achieve the desired effect consistent with the original cable. 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.
