Sulfur hexafluoride (SF6) is an extremely effective electrical insulator for medium- and high-voltage switchgear. For proper insulation, gas density must remain within certain levels. Furthermore, as SF6 is a potent greenhouse gas, it must not escape into the atmosphere. An SF6 gas density monitor warns operators of dropping levels that

High-voltage switchgear was invented at the end of the 19th century for operating motors and other electric machines. The technology has been improved over time and can now be used with voltages up to 1,100 kV. Typically, switchgear in substations are located on both the high- and low-voltage sides of large power transformers. The switchgear on

In addition to the range of standard insulators, GIPRO is specialised manufacturer of customized epoxy insulators and epoxy gis bushings for circuit breakers, fuse housing, delimiters, earth switches, gas-insulated switchgear (GIS) and air-insulated switchgears (AIS), capacitors and transformers. GIPRO supports you with your epoxy insulator, mv bushing-development as well as development of

The dielectric breakdown strength of dry air, at Standard Temperature and Pressure (STP), between spherical electrodes is approximately 33 kV/cm. This is only as a rough guide, since the actual breakdown voltage is highly dependent upon the electrode shape and size. Strong electric fields (from high voltages applied to small or pointed conductors) often produce violet-colored corona discharges
