CONSTRUCTION

PARAMETER

overview

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. The lead sheath brings an enhanced resistance to aromatic hydrocarbons.

Production Range:

Rated Voltage U0/U(Um) (kV) : 0.6/1(1.2) No. of cores : 1 , 2 , 3, 4 , 5, 3+1 , 4+1 ,3+2 Nominal cross-section(mm2): 1.5~630

Standards:

BS 6346 AS/NZS 5000,1 5000,2

Specifications

Low Voltage

construction

Conductor shaped:

RE=circular solid,CC=compacted circular stranded,SM=sector shaped stranded

Conductors:

Plain circular, compacted or shaped stranded copper or aluminium conductor

Insulation:

XLPE (cross-linked polyethylene) rated at 90°C

Assembly /Inner Sheath:

Two, Three or Four insulated conductors are laid-up together with non-hygroscopic fillers and the assembly is bedded with an extruded layer of PVC. In case of non-armoured cables, this layer may be omitted

Armour:

Aluminum/Galvanized Steel Wires, single core cables shall be Aluminium wire armour, Aluminum/Steel Tapes applied helically over the bedding of multi-core cables

Outer Sheath:

Outer sheath shall be of Extruded PVC Type ST2 as per IEC 60502-1 or Type 9 as BS 6346/5467.Special type of PVC sheathing material such as Fire Retardant PVC, Anti-Termite PVC, Anti-Rodent PVC, Sunlight resistant PVC, Oil Resistant PVC are available on special request. Also, special sheathing materials suchas LLDPE, MDPE, HDPE, LSZH, and CPE are available on request.
