APPLICATION

BS 7889 CU/XLPE/PVC 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.

STANDARDS

Basic design to to BS 7889:2012

FIRE PERFORMANCE

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

VOLTAGE RATING

600/1000V

CABLE CONSTRUCTION

ConductorAnnealed copper conductor, class 5 according to BS EN 60228.
InsulationXLPE type GP8 according to BS 7655-1.3.
Inner Covering OptionThe 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 SheathPVC Type 9 according to BS 7655-4.2.
Outer Sheath OptionUV 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.

COLOUR CODE

Insulation ColourBrown or blue
Sheath ColourBlack, other colours can be offered upon request.
