U70BS disc suspension insulator,tension insulators

U70BS disc suspension insulator is tension insulators designed, manufactured and tested according to IEC60383 standard and used for high voltage transmission & distribution line. The same porcelain disc suspension insulator IEC series include 70BL, U70BS, U70C, U100BL, U120B, U160BS, U210B, U300B and U530B.

U70BS disc suspension insulator description:
For U70BS disc suspension insulator / tension insulators, its Rated E&M failing load is 70KN. B is the connection ways, ball and socket type, which called simply BS, so U70C is a 70KN tension insulators with clevis & tongue. S means U70BS disc suspension insulator height is shorter than L’s, such as U70BL.

U70BS disc suspension insulator is made of ceramic and consists of ceramic, cap and pin. So, tension insulators are all called cap and pin suspension insulators.
