Polycab Medium Voltage High Tension cables of voltage grade ranging from 1.9/3.3 kV to 19/33 kV are suitable to use use for power supply to wide networks i.e. Commercial, Industrial and Urban / Residential. These cables are available with XLPE/EPR insulation having temperature rating of 90°C and 105°C respectively.
These cables are 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 / Ethylene Propylene Rubber thermoset insulation compound.
- Non-metallic Insulation Screen: an extruded layer of cross-linkable semi conducting compound, applied in triple extrusion with conductor screen and insulation extrusion, to eliminate micro voids and curing resulting longer life of cables
- Metallic Screen: Copper wire screen and optional helically applied copper tape screen to carry fault current
- Laying Up: in case of 3 core Cable, insulated cores laid up together with in-house developed fillers to maintain circularity of cable and optional ground wire for earthing purpose
- Inner Sheath: in case of 3 core cable, In-house developed thermoplastic compound applied over laid up core assembly
- Optional Metallic Sheath: Lead Alloy
- Optional Insect Attack Protective Layer: Polyaminde Nylon
- Outer Sheath: In-house developed thermoplastic compound having low emission of smoke and corrosive gases when exposed to fire.
