Medium and thick wall heat shrink tubes for Medium Voltage bus bar insulation – type RBM i RBH

Medium and thick wall heat shrink tubes for Medium Voltage bus bar insulation – type RBM i RBH

Application:  Designed for better insulation of bus bars in switchgears and substations.
They guarantee high anti-tracking protection and arcing resistance. The form of tube makes the installation of it more comfortable and cheape.

  • Operating temperature: -40 up to +125°C
  • The minimum shrink temperature: +110°C
  • Standard color: red
  • Halogen-free
  • Produced from modified radiation crosslinked polyethylene
