Description
SF6 gas-insulated transformers use SF6 insulation and are produced with water or air cooling. For power systems there are transformers for SVC, phase-shifting and converter transformers for HVDC. Traction transformers are supplied for electrified railways, including the Scott connection. Separate designs are made for furnaces, offshore platforms and ships, as well as mobile transformers.

Questions and answers
What is the fire point of ester-oil transformers?
Above 300 °C, so these transformers are classed as fire-safe designs.
What explosion protection systems are used?
Explosion-proof transformers are equipped with DPRS/TPRS systems.
How are SF6 gas-insulated transformers cooled?
SF6 insulation, water or air cooling. Such units are installed at underground substations.
