PVC Insulation SWA Armored Power Cable, 0.6/1kV – BS 6346

Low Voltage Power Cables
Description

BS 6346 PVC Insulation SWA Armored Power Cable

Product Overview

These cables are used for electricity supply in low voltage installation systems. They are suitable for installation indoors and outdoors, in cable ducts, underground, in power and switching stations, local energy distributions, and industrial plants, where there is no risk of mechanical damage. The lead sheath brings enhanced resistance to aromatic hydrocarbons.

Production Range:

  • Rated Voltage Uo/U (Um): 0.6/1 (1.2) kV

  • Number of Cores: 1, 2, 3, 4, 5, 3+1, 4+1, 3+2

  • Nominal Cross-Section: 1.5–630 mm²

Applications

  • Electricity supply in low voltage installation systems

  • Indoor and outdoor installation

  • Cable ducts and underground installation

  • Power and switching stations

  • Local energy distributions

  • Industrial plants where there is no risk of mechanical damage

  • Enhanced resistance to aromatic hydrocarbons due to lead sheath

  • Compliance: BS 6346, AS/NZS 5000.1, AS/NZS 5000.2

Construction

  • Conductor Shape:

    • 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: Aluminium/galvanized steel wires. Single-core cables shall be aluminium wire armour. Aluminium/steel tapes applied helically over the bedding of multi-core cables

  • Outer Sheath: Extruded PVC Type ST2 as per IEC 60502-1 or Type 9 as BS 6346/5467. Special PVC sheathing materials such as Fire Retardant PVC, Anti-Termite PVC, Anti-Rodent PVC, Sunlight Resistant PVC, Oil Resistant PVC are available on special request. Special sheathing materials such as LLDPE, MDPE, HDPE, LSZH, and CPE are available on request
