Applications

• As an overwrap for protection of terminating high-voltage cables against arcing and tracking. High-voltage cables with these insulations should be overwrapped: 
  • Butyl rubber 
  • Oil-base rubber 
  • Ethylene propylene rubber 
  • P.V.C. 
  • Low and high-density polyethylene cross-linked 
• As primary insulation where Class H (180ºC/356ºF) temperatures are encountered i.e., silicone rubber cables. 
• As splice overwrap on spacer cable operating at 15kV and above.
