Abstract
Description
technical field
[0001] The invention belongs to the technical field of materials. More specifically, the present invention relates to a waterproof sealing electrical stress relieving glue, and also relates to a production method of the waterproof sealing electrical stress relieving glue. Background technique
[0002] In the construction process of high-voltage transmission cable terminals or joints, the cable is cut into sections, and the structure of the cable needs to be restored layer by layer. In the process of restoring the semiconducting layer, the original semiconducting layer of the cable is cut off, and the electric field is distorted. If the distribution is uneven, discharge will occur due to excessive concentration of electrical stress, which will cause electrical breakdown. In 6~35KV cables, materials with specific electrical parameters are usually used to solve the point stress problem, such as electrical stress evacuation glue. Since the current electrical st...
