Primary Insulation	-	General purpose PVC / Heat Resistant PVC / PE / XLPE / PTFE / PFA / EPR / Fibre Glass / FEP / Silicone Rubber
Screening	-	Individual and/or overall with following options - - Aluminum Mylar/Copper Tape with Tinned Copper Drain Wire or - Braided with Bare or Tinned or Nickel Plated or Silver Plated Copper
Inner Sheath	-	PVC / HRPVC / FRPVC / FRLS PVC / ZHFR / LSF
Armouring	-	GI round Wire / Flat strip or Wire Braiding
Outer Sheath	-	PVC / HRPVC / FRPVC / FRLS PVC / ZHFR / LSF
Rip Cord	-	For easy removal of sheath
Standards	-	BS-5308 Part-1 & 2, BS-7655, IEC-189 (1 & 2), VDE-0815 & 0816 and BS EN 50288-7
