POLYCAB MEDIUM VOLTAGE HIGH TENSION CABLE CONFORMING TO IS 7098-P2

Polycab Single core and three core medium voltage high tension cables of voltage grade ranging from 1.9/3.3kV to 19/33 kV are widely used for power distribution, external and direct burial applications in power network system, underground, and in cable ducting. These cables are available with XLPE insulation having temperature rating of 90°C.

These cables are also available with halogen free flame retardant in characteristic and provide continuous load and Extra-protection from short circuit and Fire.

Technical advantages:

  • Conductor: High conductivity annealed plain stranded compacted aluminium / copper conductor produced in-house from state-of-the art machine.
  • Conductor Screen: An extruded layer of cross-linkable semi conducting compound to eliminate sharp points on conductor surface and also nullifies chance of electric discharge at interface between conductor / insulation
  • Insulation: In-house developed high insulation resistance cross-linked polyethylene thermoset insulation compound.
  • Non-metallic Insulation Screen: An extruded layer of cross-linkable semi conducting compound, applied in triple extrusion process with conductor screen and extruded insulation, to eliminate micro voids and curing, resulting longer life of cables
  • Metallic Screen: A helically applied copper tape screen to carry fault current
  • Laying Up: in case of 3 cores Cable, insulated cores laid up together with in-house developed fillers to maintain circularity of cable
  • Inner Sheath: In-house developed thermoplastic PVC compound/ halogen free compound having low emission of smoke and corrosive gases when exposed to fire and also ensures circular shape of cable
  • Armour: Aluminium / Galvanised Steel Round Wire Armoured to give mechanical protection and also acts as return path for earth fault current
  • Outer Sheath: In-house developed thermoplastic PVC compound/ halogen free compound having low emission of smoke and corrosive gases when exposed to fire.
