How to detect the voltage resistance of rubber insulation board

The rubber-plastic insulation board is a closed-cell structure with extremely small water vapor permeability, which can maintain a low thermal conductivity for a long time, and the rubber-plastic board is very safe to use, neither irritating the skin nor endangering health. The rubber-plastic material has the functions of preventing mold growth and avoiding pests or mice biting. The rubber-plastic material is also a very good pipe protection material to prevent the gas underneath from corroding the pipe and rusting.

In general, we should pay attention to the voltage resistance of the rubber-plastic board when using rubber-plastic board. Usually, we put the rubber-plastic insulation board on a frame covered with metal plates, put a metal plate with each side less than 10cm of the insulation plate on the rubber-plastic board, and place an electrode connected to the transformer on the metal plate. The other electrode is connected to the rubber-plastic board broken down by high voltage during inspection on the other side of the rubber-plastic insulation board. Repair is allowed, but the hole, qualified can only be used, and can only be used as secondary products. In order to detect the rubber insulation board voltage resistance.
