Product Features
 
For Medium Voltage Insulation
 
Ikebana NTT, heat shrink medium wall tubing, is a non-tracking tubing for indoor and outdoor applications for termination of medium voltage XLPE and paper insulated power cables. Ikebana NTT has good resistance to tracking and erosion which provides excellent electrical insulation to the components inside. It offers good protection from environmental effects, ultra-violet radiation and moisture. The tough cross-linked polyolefin material provides good mechanical protection.

Ikebana NTT is easy to install. A common gas torch is required to heat and recover the tubes onto the power cables or accessories. Ikebana NTT has a high shrink ratio which allows it to be used with a wide range of cable sizes.
 
Ikebana heat shrink medium wall non-tracking tubes have:
 
  • EXCELLENT HEAT RESISTANCE: Made from cross linked polyolefin, non-melting.
  • LARGE APPLICATION RANGE: Expansion ratio 3:1.
  • CONTINUOUS OPERATING TEMPERATURE: 55ºC TO 125ºC.
  • EXCELLENT TRACKING AND EROSION RESISTANCE.
  • SHRINKING TEMPERATURE: Min. 125ºC.
  • EASY INSTALLATION: On site using gas torch or hot air blower.
