SF6 circuit breaker bushing insulator

SF6 circuit breaker bushing insulator offers great advantages in many applications. Cost-efficient design with less material, lower weight and gas volume reduction for SF6-filled products are just some of benefits of tapered insulators.

SF6 circuit breaker bushing insulator

The SF6 circuit breaker bushing insulators are designed according to the mechanical requirements of our customers to manage both bending forces and the inner pressures to which the insulators are subjected during their service lives. An inner layer of polyester liner is normally used. This is a requirement for insulators used in gas-insulated circuit breaker applications to be able to withstand the decomposition products of the insulation gas

High strength flange design for SF6 circuit breaker bushing insulator
The fiberglass tubes are fitted into high strength and high resistant aluminum alloy casted flanges using a special process, which results in a combined shrink fit and adhesive bond. The result is an extremely strong, gas-tight and leakproof joint. Anodized flange solutions are available for extreme environments and special applications.

SF6 circuit breaker bushing insulator is one main kind of hollow bushing insulator used with arrester and switch.
