First, silicone coatings have excellent dielectric strength. Dielectric strength is a measure of the ability of a material to withstand voltage in an electric field without breakdown. The dielectric strength of silicone coatings is usually between 20-50 kV/mm, which can effectively prevent electrical breakdown and ensure the safe operation of electrical equipment. In high-voltage applications, silicone coatings can not only serve as insulating media, but also prevent arcing and leakage. This is crucial for high-voltage transformers, switchgear and other high-voltage electrical equipment.
