Pfisterer High Voltage Bushings up to 33kV Cables
Pfisterer High Voltage Bushings up to 33kV Cables
Pfisterer Connex HV bushings require less space than conventional type high voltage connectors - high voltage elbow bushings are suitable for ring main units, circuit breakers, switchgears, transformers, capacitors and motor applications with 250amp and 650amp current ratings.
Pfisterer Connex HV bushings are available for 33kV and 52kV voltage systems insulated by SF6 gas or oil. HV bushings feature M12 standard threated connections, bolt-on type connection and are available in sizes 1, 2 or 3 for gas or oil insulated HV electrical equipment systems.

Pfisterer Connex HV insulators permit air-insulated switchgear to be installed with touch safe high voltage cable terminations up to 33kV. Switching zones and cable termination zones can be insulated safely and easily - available to suit Pfisterer Connex HV bushings sizes 1, 2 and 3 with 630amp, 800amp and 1250amp current ratings.
SF6 Gas - Dielectric and Insulating Medium for HV Systems
SF6 gas is used in the electrical industry as a gaseous dielectric medium for high-voltage (33kV and above) circuit breakers, switchgear and other electrical equipment. SF6 gas replaces oil filled circuit breakers (OCBs) that can contain harmful PCBs. SF6 gas under pressure is used as an insulator in gas insulated switchgear (GIS) because it has a much higher dielectric strength than air or dry nitrogen enabling switchgear manufacturers to significantly reduce the size of electrical gear. This makes GIS more suitable for certain high voltage applications such as indoor placement, as opposed to air-insulated electrical gear which takes up considerably more space. Gas insulated electrical switchgear is also more resistant to the effects of pollution and climate as well as being more reliable in long-term operation because of its controlled operating environment.
