The most important thing in choosing rubber as an insulating plate is that the rubber has good insulation, which allows the insulating rubber plate to work normally under high voltage, without being affected by high voltage.

Tips
The insulating rubber sheet made of rubber is also waterproof, and the insulating rubber sheet is laid in the air, which effectively avoids the accident of water penetration and plays a role in maintaining the safety of the staff. Rubber is not only used in the power industry but also widely used in other industrial fields. The molecular chain does not contain polar groups and is a non-polar rubber. Only resistant to some polar solvents. Therefore, its oil resistance is very poor. The insulating rubber sheet has good alkali resistance, but is not resistant to strong acid.
The extreme elasticity of rubber has become the first reason for the choice of the 6mm*15kV insulating rubber sheet. Good elasticity makes the insulating rubber sheet difficult to break during other processes such as stopping the floor, and has good stretch ability and extensibility.
