heat shrink tubing :
Thin wall heat shrinkable tubing for insulating and protecting bus bar against flashover caused by accidental bridging. Allows the air space 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 1kvProtects 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.
