CYG-BT(35H) High Voltage Flame-retardant Wall Heat Shrinkable Busbar Sleeving
Category: Heat Shrink Dual Wall Sleeving
Material: radiation cross-linked modified polyolefin material
Shrink ratio: 2.5: 1
Features:
• Environmentally friendly, low smoke, the product complies "RoHS" environmental standards;
• has good insulating properties; • have good flexibility; • Minimum shrink temperature: 110 ℃;
Application: This product is widely used in low voltage switch cabinet bus insulation protection, effectively prevent personal injury or death caused by the charged row naked; to avoid a small animal and the conductor ride then cause a short circuit, discharge failure occurs, to prevent corrosion, contamination, flashover occurs, increase insulation margin, effectively shortening the distance between the stage, the pole distance, create favorable conditions for switchgear compact design.
