How long is the small busbar on the top of the high-voltage switchgear

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 may use metal tubes 50 millimetres (2.0 in) in diameter or more as busbars. use very large busbars to carry tens of thousands of to the that.
