CYG-BT 1T 1kV Heat shrinkable busbar casing

Application field: This product is widely used in busbar insulation protection of high and low voltage switchgear, effectively preventing personal injury and death caused by bare bare row; avoiding short circuit and discharge failure caused by small animals and electrical conductors, preventing corrosion, pollution and flashover Occurs, increases the insulation margin, effectively shortens the inter-stage distance and the pole-to-ground distance, and creates favorable conditions for the miniaturization of the switchgear.
