ANSI 52-1 52-2 52-3 52-4 Porcelain Disc Suspension Ceramic Insulator for Transmission

Porcelain disc suspension insulator is designed to be assembled together to be insulator strings (also called strain insulators),which can divide into Ball & Socket Type and Clevis & Tongue Type.This structure enables them form the insulator string by fitting into themselves one another as per voltage requirement.ANSI Class/StandardANSI 52-3Unit Spacing (H) - mm146mmNominal Diameter (D) -mm254mmCreepage Distance292mmPower frequency puncture voltage110kVPower frequency flashover voltage  Dry80kV Wet50kVCritical impulse flashover voltage  Positive125kV Negative130kVRadio influence voltage Test voltage to ground10kV Max.
