Polycab Medium Voltage High Tension cables of voltage grade ranging from 3.6 kV to 36 kV are widely used for power distribution, external and direct burial applications in power network system, underground, in cable ducting and in direct burial condition. These cables are available with XLPE insulation having temperature rating of 90°C.
These cables are halogen free flame retardant in characteristic and provide continuous load and Extraprotection 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 with conductor screen and insulation extrusion, to eliminate micro voids and curing resulting longer life of cables
- Metallic Screen: a helically applied copper tape screen to carry fault current
