In high-voltage electric connections, high voltage insulating silicone grease plays an important role,dielectric greases are idea for electrically insulate, dielectric silicone grease is a prior choice for electric industry,repel moisture and anti corrosion. It can guarantee that the lubricant used in these connections not break down under the extreme conditions.Whether it is the high-voltage electric power industry or the new energy vehicle industry,insulating grease is being used more and more widely ,needs to meet new insulation requirements and compatible with new materials as well .
