CABLE TYPE

Cu/XLPE/PVC/SWA/PVC cable to BS 5467
Cu/XLPE/PVC/SWA/MDPE cable to BS 5467
APPLICATION
The power and auxiliary cables outlined in this section find use in powernetworks, underground, outdoor and indoor applications and for use in cable ducting. These cables can be used indoors or outdoors, but some reservations are necessary concerning cables for direct burial in the ground or for use in wet conditions. Cables laid directly in the ground, particularly in sustained wet conditions, should have an extruded bedding and preferably MDPE – Medium Density Polyethylene as the outer sheath material.
It is essential that the type of cable ordered is suitable for its intended use.
CONSTRUCTION
Conductor:
Copper Circular stranded (Non-compacted or Compacted) Class 2 to IEC 60228 or BS EN 60228 (previously BS 6360)
Insulation:
XLPE – material and thickness as per IEC 60502 or BS 5467 and rated for 90°C continuous operation
Assembly
For multicore cables, two, three of four insulated conductors are laid-up together with non-hygroscopic fillers compatible with the insulation material and the assembly is bedded with an extruded layer of PVC.
Core Identification:
Single Core : Red or Black
Two Cores : Red, Black
Three Cores : Red, Yellow, Blue
Four Cores : Red, Yellow, Blue, Black
Five Cores : Red, Yellow, Blue, Black, Green/Yellow
Above Five Cores : White numerals printed on black core insulation.
Cables with special colour code are also available, based on special request.
Bedding
PVC Extruded bedding serves as a bedding for the armour and as protection for the laid-up cores.
Armour
Galvanized Steel Wires applied helically over bedding as per IEC 60502, BS 5467. (Single core cables shall be with Aluminium wire armour).
Cables with Double steel tapes applied helically over the bedding of multi- core cables as per IEC 60502 are also available on request.
Outer Sheath
Outer sheath shall be extruded PVC type ST2 as per IEC 60502, Black. Special consideration must be taken into account when the cable is intended for use in hostile environments and as such special type of PVC sheathing material such as Fire retardant PVC, anti-termite and anti-rodent PVC, Ultraviolet PVC, Oil resistant PVC etc are available on request. Special sheathing materials such as LLDPE, MDPE, HDPE, CPE etc can also be made available on special request.
All sheaths are designed with easy strip characteristics to reduce the time and cost of cable preparation during installation.
All sheaths are designed with easy strip characteristics to reduce the time and cost of cable preparation during installation.
In addition, finished cable are marked on the outer sheath to aid cable identification at site.
