Renew used transformer oil/ dielectric oil regeneration ... Oil regeneration system (Series ZYD-I) has been specially designed for on site use to completely regenerate insulating oils in energized or de-energized transformers especially for the power, which is over 110KV. Also it can inject the insulating oil into the transformers on-line.

SF6 Gas Insulated Equipment | Vaisala unique sample cell allows dew point measurement at both in gas pressure and in ambient atmospheric pressure. The cell meets and even exceeds environmental regulations by ensuring protection against accidental discharge of SF6, requiring minimal amount of SF6 for sampling, and enabling collection and recycling of SF6.

Switchgear - Wikipedia switchgear may be a simple open-air isolator switch or it may be insulated by some other substance. An effective although more costly form of switchgear is the gas-insulated switchgear (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF 6). Other common types are oil or vacuum insulated switchgear.
