NTMT24KV BUS BAR 24KV Heat shrink sleeve with internal adhesive

The NTMT24KV Series heat shrink sleeve is made of polyolefin. The inner part of the sleeve is coated with a hot-melt adhesive which, during the shrinking phase, melts around the object in order to guarantee the best fixing and protection from water and moisture infiltration. It is usually used to electrically and mechanically isolate bus bars up to 24KV and irregularly shaped objects, where it is not possible to mount a closed sleeve.

  • 2:1 shrinkage ratio. The sleeve shrinks 2 times with respect to the initial diameter. Sleeves for bus-bar 6÷24 KV – 36 KV
  • Available diameters: from 25.0mm to 100.0mm
  • Operating temperature from -55°C to +105°C
  • Conforms to ASTMD2671, ISO52, IEC243, IEC93, IEC250
