S1-35 Halogen free flame retardant bus bar insulation heat shrinkable tubing
 
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
 Flame resistant with oxygen index higher than 27
 Available in continuous length roll form for convenient and economical installation
 
Temperature Rang
 Operating Temperature: -40~105¡æ
 Shrink Temperature: 125¡æ
 
Colour:red
