AI Technical Summary

Problems solved by technology

Since the current electrical stress evacuation glue does not have the effect of waterproof sealing, it is necessary to use waterproof sealant to waterproof and seal the cables. The operation process is cumbersome and inefficient.
For example, the products protected by patents: CN90103331.6, CN200910067125.5, CN200910140609.8, CN201110246946.2, CN200910140610.0 and the products currently on the market are all electrical stress evacuation adhesives without waterproof sealing effect

Abstract

The invention relates to a waterproof sealing electric stress evacuation glue and a production method thereof. The dielectric constant of the waterproof sealing electrical stress evacuation glue is 14-25, and the volume resistivity is 1.0×108-1.0×1010Ω·cm. The production method of the electrical stress evacuation adhesive includes preparing mixed rubber by using chloroprene rubber, brominated butyl rubber and various auxiliary agents, then extruding and pressing sheet-shaped strips, and cutting to obtain waterproof and sealed electrical stress evacuation adhesive. Compared with the existing electrical stress evacuation adhesive, the waterproof sealing electrical stress evacuation adhesive of the present invention has both the electrical stress evacuation function and the waterproof sealing function, which can reduce the operation steps in the construction process, simplify and facilitate the construction, and can be used in large areas. Improve work efficiency to a certain extent.

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...
