Direct and complete cleansing of transformer oil ...· Highlights A single-batch process is effective in the cleansing of transformer oil from any trace of PCBs. Transformer oil can thus be recycled at a cheap price, using commercial metallic Ca and simple alcohols (methanol, ethanol and isopropanol). The hydrodechlorination is complete, leaving only traces of mono- and dichlorobiphenyl compounds with the lowest toxicity in the PCB family.Cited by: 5[email protected]

Introduction to Gas Insulated Substations / Switchgears (GIS) insulated switchgear parts. As the dielectric strength of SF6 gas is higher than air, the clearances required are smaller. Hence the overall size of each equipment and the complete sub-station is reduced. The various modules are factory assembled and are filled with SF6 gas. Thereafter, they are taken to site for final assembly.
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.
