U70b Power Suspension Tempered Glass Insulator

U70b Power Suspension Tempered Glass Insulator. High voltage resistance: With high insulation resistance, it can effectively withstand power frequency overvoltage and lightning impulse. Strong anti pollution: The surface has strong hydrophobicity and is not easily affected by moisture to form a conductive film, significantly improving the anti pollution flashover ability. Stable field strength: The electric field distribution is relatively uniform, which can effectively reduce corona losses and radio interference. Anti breakdown: The design ensures that the breakdown voltage is higher than the flashover voltage, and even if surface discharge occurs, it usually does not permanently damage the body, making it sa.
