HEAT SHRINK MEDIUM VOLTAGE INSULATION TUBING
Qualtek Electronics
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.
