However, as the distributors of Tamco medium voltage switchgear in South Africa, we do not profess to be experts on SF 6 that has been used as an insulating medium for over half a century. Malaysian Switchgear’s expertise lies in the layout design, wiring, testing, installation, commissioning and maintenance of the Tamco range of medium voltage switchgear panels up to 36 kV, as well as dry ice cleaning of compromised sub stations.

Power factor testing of insulating gas circuit breakers | TD Guardian

At the time of production, gaz sf6 gas circuit breakers are subject to a high-voltage withstand test. This incorporates an AC High-Potential (Hi-Pot) test transformer capable of achieving the required high-voltage levels (per industry standards). Therefore, field Hi-Pot testing is also not necessary or required. The insulating material used in the manufacture of modern sf 6 gas circuit breakers is synthetic, which have no capacitor characteristics and have no ability to absorb moisture.
