1KV LOW VOLTAGE HEAT SHRINK INSULATION TUBE【LVIT1】

Thin wall heat shrinkable tubing for insulating and protecting bus bar against flashover caused by accidental bridging. Allows the air spacing between bus bar to be kept at minimum when space is limited in switchgear cabinets. Easy to position on a variety of curved and bent bus bar of both rectangular and circular shapes.

Features and Benefits
★Reduces bus bar clearance requirement.
★Provides more freedom in designing switchgear cabinets when space is limited.
★Suitable for insulating bus bar up to 1kv.
★Protects against short circuit and electrical leakage caused by small animals.
★Protects against corrosion and other contaminants that may cause accidental flashover.
★Available in continuous length for convenient and economical installation.
★Highly flame retardant.
★RoHS compliant, halogen free.
