FIREGUARD Flame Retardant Cables

Fire retardant cable(Fireguard)

600/1000V PVC Insulated, PVC Sheathed, Armoured Power Cables to BS 6346 (2-5 Cores)

FGD400 1VVMV-R (CU/PVC/PVC/SWA/PVC 600/1000V Class 2)

Application

The cables are intended for use in fixed installations in industrial areas, buildings and similar applications.

Standards

Basic design to BS 6346

FGD400 1VVMV-R (CU/PVC/PVC/SWA/PVC 600/1000V Class 2)

Fire Performance

Flame Retardance (Single Vertical Wire Test)

BS EN 50265-2-1

Voltage Rating

600/1000V

Cable Construction

Conductor：Annealed copper wire, stranded according to BS 6360 class 2.

Insulation：PVC TI 1 according to BS 7655-3.1.

Bedding：Extruded PVC or taped bedding comprising two or more layers of PVC tape or other synthetic tape (for

cables having a nominal conductor area of 16mm² and above).

Armouring：Galvanized steel wire

Outer Sheath：PVC TM 1 according to BS 7655-4.1.

Outer Sheath Option：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.
