Electrical Equipment Production and Use

Electrical Equipment Production and Use icon.This source category comprises electrical transmission and distribution systems and facilities that manufacture or refurbish electrical equipment.

The electrical transmission and distribution subsector consists of all electric transmission and distribution equipment insulated with or containing sulfur hexafluoride (SF6 ) or perfluorocarbons (PFCs) within an electric power system. This equipment includes but is not limited to gas-insulated substations; circuit breakers; switchgear, including closed-pressure and hermetically sealed-pressure switchgear; gas-insulated lines containing SF6 or PFCs; and gas containers such as pressurized cylinders, gas carts, electric power transformers, and other containers of SF6  or PFCs. Emissions are from leakage of fluorinated greenhouse gases during the servicing and use of the equipment.

The electrical equipment manufacturing or refurbishment subsector consists of electrical equipment manufacturers and refurbishers of closed-pressure equipment and sealed pressure equipment that is insulated with SF6  or PFCs. This equipment includes gas insulated substations, circuit breakers and other switchgear, gas-insulated lines, or power transformers containing SF6 or PFCs.
