Applications These cables are used for electricity supply in low voltage
installation system, They are suitable for installation in indoors
and outdoors, in cable ducts, under ground, in power and switching
stations, local energy distributions, industrial plants, where
there is no risk of mechanical damage.
Construction 1. Conductors The conductors shall be either of Class 1 or Class 2 of plain or
metal-coated annealed copper or of plain aluminium or aluminium
alloy, or of Class 5 of plain or metal-coated copper in accordance
with IEC 60228.
2. Insulation - Mica tape.
- XLPE material and thickness shall be as per IEC 60502 or BS 5467
rated for 90°C continuous operation.
3. Assembly / Inner Covering The inner coverings may be extruded or lapped. For cables with
circular cores, except cables with more than five cores, a lapped
inner covering shall be permitted only if the interstices between
the cores are substantially filled. A suitable binder is permitted
before application of an extruded inner covering. The material is
compatible with the insulating material,The materials used for
inner coverings and fillers shall be suitable for the operating
temperature of the cable and compatible with the insulating
material.For halogen free cables, the inner covering and fillers
shall also be halogen free compound.
4. Armour Aluminum/galvanized steel/steel wires applied helically over the
Inner Covering as per IEC 60502-1, or double aluminum/steel tapes
and copper/tinned copper wire can also be manufactured upon
request.
5. Outer Sheath Outer sheath shall be of extruded PVC Type ST1/ST2 as per IEC
60502-1, Polyethylene type ST3/ST7, Halogen free compound ST8,
Polychloroprene, chlorosulfonated polyethylene or similar polymers,
type SE1 are also available on request.
6. Fire Performance of Cable Sheaths Cables can be supplied with special flame retardant PVC outer
sheath to comply with the flame test requirements of IEC
60332-3-22, IEC 60332-3-23 and IEC 60332-3-24, Halogen Free
material comply to IEC60754-1/2 and IEC 60684-2. |
