Product DescriptionSuspension insulators are designed to be connected in a string (usually two or more) to provide higher voltage protection than any single insulator. Suspension insulators are often used on high-voltage transmission towers, as shown in the figure below. Ceramic is by far the most commonly used insulation material, but there are also a variety of glass styles. Porcelain suspension insulators have revolutionized the power distribution industry, providing higher voltage protection - they are used on several 1,000kV DC transmission lines.Can be used for any voltage and pollution level by changing the number of insulatorsMechanical strength up to 530kNHigh reliability brought by technology accumulationExcellent long-term performance Product Parameters ANSI Class52-552-652-852-9A/B52-1052-1152-12Porcelain Disc Diameter, D (mm)254254280108280300300Unit Spacing, H (mm)146146146160165156178Creepage Distance (mm)292292305171305381381Combined M&E Strength (kN)11111116044160222222Impact Strength (N-m)77105101010Routine Proof Test Load (kN)55.555.5802280111111Time Load Test Value (kN)676710727107133133Low Frequency Flashover VoltageDry (kV)80808060808080Wet (kV)50505030505050Critical Impulse Flashover VoltagePos., (kV)125125125100125140140Neg., (kV)13013013090130140140Low Frequency Puncture Voltage (kV)11011011080110125125Radio Influence Voltage DataTest Voltage to Ground (kV)1010107.5101010Max.
