FIREGUARD Flame Retardant Cables 

Flame Retardant Power & Control Cables

600/1000V XLPE Insulated, PVC Sheathed, Armoured Power Cables (2-5 Cores)

FGD400 1RV-R (CU/XLPE/PVC 600/1000V Class 2)
FGD400 1RVMV-R (CU/XLPE/PVC/SWA/PVC 600/1000V Class 2)

Flame Retardant Power & Control Cables

APPLICATION
The cables are mainly used in power stations, mass transit underground passenger systems,
airports, petrochemical plants, hotels, hospitals, and high-rise buildings.

STANDARDS
Basic design adapted to IEC 60502-1; BS 5467

FIRE PERFORMANCE

EN 60332-3-24 (cat. C); IEC 60332-3-24; BS EN 60332-3-24; VDE 0482-332-3; NBN C 30-004 (cat. F2); NF C32-070-2.2(C1); CEI 20-22/3-4; EN 50266-2-4*; DIN VDE 0482-266-2-4

Note: Asterisk ** denotes that the standard compliance is optional, depending on the oxygen index of the PVC
compound and the cable design.

VOLTAGE RATING
600/1000V

CABLE CONSTRUCTION
Conductor: Plain annealed copper wire, stranded according to IEC(EN) 60228 class 2.
Insulation: Extruded cross-linked XLPE compound.
Inner Sheath(optional): PVC Compound
Armouring(optional): Galvanized Steel Wire
Outer Sheath: Thermoplastic PVC compound. UV resistance, hydrocarbon resistance, oil resistance,
anti rodent and anti termite properties can be offered as option. Compliance to fire performance
standard (IEC 60332-1, IEC 60332-3, UL 1581, UL 1666 etc) depends on the oxygen index of the
PVC compound and the overall cable design. LSPVC can also be provided upon request.
