SH-V type compact high-pressure bus duct

A compact high-voltage bus duct that provides high dielectric strength and electrical safety due to the insulation of the conductor.

Due to the insulation of the conductor, the occupied area has been reduced compared to conventional high-voltage bus ducts, allowing for a comfortable connection to distribution boards with a width of 600mm to 700mm. Additionally, to ensure that all insulators can be cleaned, the duct has a structure that allows for opening along its entire length on both the top and bottom, making it a safe design that can accommodate insulation degradation in harsh environments. For more details, please contact us via the inquiry form.
