High Voltage Busbars: Typically refer to busbars with a rated voltage of 1kV and above, including common voltages such as 10kV,
The busbar''s material composition and cross-sectional size determine the maximum current it can safely carry. Busbars can have a cross-sectional area of as little as 10 square millimetres (0.016 sq in), but electrical substations may use metal tubes 50 millimetres (2.0 in) in diameter or more as busbars.
