CYG-BT 1T 1kV Heat shrinkable busbar casing
Category: Heat Shrink Dual Wall Sleeving
Material: Irradiation cross-linked modified polyolefin material
Shrinkage ratio: 2.5:1
Features:
• Environmentally friendly, low smoke, products meet the "RoHS" environmental standards;
• Has good insulation properties;
• has good flexibility;
• Minimum shrinkage temperature: 110 ° C;
• Voltage rating: CYG-BT 1T: 1kV CYG-BT 10M: 10kV
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.
