600/1000V XLPE Insulated, PVC Sheathed, Unarmoured Power Cables to BS 7889 (2-5 Cores)

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

Applications

BS 7889 600/1000V XLPE Insulated, PVC Sheathed Unarmoured Power Cables are mainly use in fixed installations in industrial areas, buildings and similar applications but not for burial in the ground, either directly or in ducts.

Standard

Basic design to BS 7889:2012

Fire Performance

Flame Retardance (Single Vertical Wire Test) BS EN 60332-1-2

Voltage Rating

600/1000V

Construction

600/1000V XLPE Insulated, PVC Sheathed, Unarmoured Power Cables Power Cables to BS 7889 (2-5 Cores)
Conductor Annealed copper wire, stranded according to BS EN 60228 class 2.
Insulation XLPE type GP8 according to BS 7655-1.3.
Filling: If necessary, the formation of a compact and reasonably circular cable shall be achieved by one of the following methods. a) The application of synthetic fillers or binder tape(s). b) The optional inner covering. c) The sheath provided it effectively fills the interstices. d) Any combination of the above. Inner Covering Option: The optional inner covering, where used, shall consist of an extruded layer of synthetic polymeric material. It shall surround the single core and the laid-up two, three, four or five cores, giving the assembly a practically circular shape.
Outer Sheath PVC Type 9 according to BS 7655-4.2.
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.
