Voltage class 36KV ideal for high voltage bus bar insulation
Heavy wall heat shrinkable tubing for protection and insulation of bus bar against accidents caused by electrified bare bus bar
Applications
 Bus bar insulation and protection In switchgears cabinets where space is limited and air spacing between bus bars need to be kept at minimal
Features/Benefits
Reduce bus bar clearance requirement Give designer more freedom in designing switchgear cabinets when space is premium Protects against accidental flashover up to 36kV Protects against short circuit and electrical leakage caused small animals Protects against corrosion dirt and other contaminants that may cause accidental flashover Halogen Free Available in continuous length roll form for convenient and economical installation
