  • Gas insulated power transformers: A growing technology

    Most power transformers use oil as an insulating and cooling medium but, where substations are located in restricted spaces, gas is used for this purpose. Gas insulated switchgear is commonly used in substations and the development of gas insulated transformers allows complete integration of substation equipment with resultant space and cost savings.
