ANSI 56-3 /56-1/56-2/56-3/56-4 C29.6 Transmission Line High Voltage Porcelain Pin Insulators

Basic Info

Product Description

Pin insulator is a component that supports or suspends a wire and forms electrical insulation between the tower and the wire . The pin type porcelain insulator and cast steel are cemented together, and the surface of the porcelain is coated with glaze to improve the insulation of the insulator.

Pin Insulator should have sufficient insulation strength and mechanical strength. During operation, they should not only withstand the effects of working voltage and overvoltage, but also have sufficient resistance to the erosion of chemical impurities, and need to be able to adapt to the changes in temperature and the influence of the surrounding environment.

There are several standards of porcelain pin insulators : ANSI STANDARD, BS STANDARD, DIN STANDARD

For ANSI STANDARD: there are types :55-1 55-2 55-3 55-4 55-5 ,56-1 56-2 56-3 56-4 56-4 etc.

For BS AND DIN STANDARD : there are types:P-6-Y,P-11-Y, P-15-Y,P-22-Y,P-33-Y,P-44-Y,PW-15Y,PW-22Y,PW-33Y, ST-10,ST-15,ST-20,ST-36 ETC
