Mineral Insulated Copper Cable (MI Power Cable)

Mineral Insulated Copper cable belongs to electric cable class.

  • Outer Sheath: Copper Sheath with a melting point of 1083°C
  • Insulation: Magnesium oxide insulator, hardly compressed, with a melting point of 2400°C.
  • Conductor: Annealed conductor of 99.9% of pure electrolytic copper wire, with a melting point of 1083°C Applicable
  • Covering: Addition LSF (Low Smoke Fumes) outer covering.
  • Applicable Standard: IEC/EN 60702 Part 1, BS6387, IEC60331, Categories C, W & Z
  • Operating Temperature: Maximum 250°C (But will operate up to a temperature of 1083°C but this will reduce the life of the cable)
  • Voltage: 450/750 V (Heavy Duty Grade Cable )
    300/500 V (Light Duty Grade Cable)
