2021-2-2The SF6 gas insulated transformer is valued for its high non-flammability, insulation performance, and safety. These characteristics contribute to the simple and oil-leakage free installation. In addition, the direct connection of Gas Insulated Switchgear and Gas Insulated Transformer would constitute a totally gas insulated substation.
