HEAT SHRINK MEDIUM VOLTAGE INSULATION TUBING  
QBM, QBT  
HALOGEN FREE, HEAT SHRINKABLE, 11-36kV  
BUS BAR INSULATION PROTECTION TUBING  
SHRINK RATIO 2.5:1  
Features/Applications  
Made from specially formulated radiation cross-linked halogen-free  
compounds. The carefully produced product can provide high resistance  
to tracking and arcing. Used to enhance the insulation properties of bus  
bar in switchgear and substations. The continuous length of supplied  
products makes it more convenient and economical.  
Operating temperature: -55°C to +105°C  
Minimum shrink temperature: 110°C  
RoHS Compliant  
Halogen free
