Introduction        
Thick-walled heat-shrinkable tube, made of environmentally friendly flame-retardant polyolefin material, can be used in 6~36kV power switch cabinets to provide insulation enhancement and protection against flashover or accidental induced discharge. Particularly suitable for switch cabinets where space is limited, it can be used for round and rectangular copper or aluminum busbars.

 

Features        
Operating temperature: -40~105         
Voltage level: 6~36kV        
Halogen-free and environmentally friendly, RoHS compliant        
Minimum full shrinkage temperature: 125         
Shrink ratio: 2:12.5:1        
Standard Colors : Red, Yellow, Green
