IEC 60332 for fire resistant cable

    DESCRIPTION

       This specification covers single core cables and three core armored or unarmored cables, rated at 1.9/3.6KV and conformed to IEC 60502-1, IEC60331 & IEC 60332.

    CONSTRUCTION

1.    Conductor

Plain, annealed electrolytic copper or Aluminum conductors, circular stranded, conforming to the applicable requirements of IEC 60228.

2.    Insulation

XLPE (cross-linked polyethylene) rated 90℃, 105℃, 125℃, 135℃.

3.    Colours for core identification

Single core –natural                               Optional colours

Three cores- red, yellow and blue         Single core- natural

                                                                  Three cores- brown, black and grey

4.    Assembly

Three insulated conductors are laid up together, if necessary, filled with non-hygroscopic material compatible with insulation and covered with layer of PVC bedding which may be an integral part of the filling

5.   Armor

Single core- Aluminum wire shall be applied over the PVC bedding

Multi-core- Galvanized steel wire shall be applied over the PVC bedding.

6.   Sheath

PVC or PO (Halogen free or fire retardant compound on special request), thermoplastic material conforming to IEC 60502-1.

Applications:

These cables are most suitable for underground burial where there is a risk of mechanical damage.
