Busbar Insulation Protection Tubing(HBM/HBT)
Applications/Features
HBM/HBT
is made from apecially formulated radiation crosslinked
polyolefin halogen
free compounds. Thus carefully produced can
provide high resistance
to tracking and arcing.Used to enhance
the insulation.Properties of busbar
in switchgear and substation.
The continuous length of supplied products makes
it to be used
more conveniently and economically.
