4 Core XLPE Insulated STA Armoured 25mm 35mm 50mm Power Cable
Standard:
IEC60502,and BS6346, VDE, AS/NZS etc or as customer's request.
Application of Armoured Power Cable:
4 core armoured cable has excellent chemical corrosion resistance, but also has the properties of flame retardant and non water-absorption and suitable for underground installation, which can withstand certain mechanical pressure,but can’t withstand mechanical tension.

Construction of Armoured Power Cable :
Conductors:Copper or Aluminium conductor, round standed or Shaped, Class 2 to IEC 60228, BS EN 60228. For smaller sizes, a solid round conductor, Class 1 as per IEC 60228, BS EN 60228 can also be supplied upon request.
Insulation:XLPE material and thickness shall be as per IEC 60502 or BS 5467 rated for 90°C continuous operation.
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 applied helically over the bedding as per IEC 60502 or as per BS 5467, BS 6346. Single core cables shall be Aluminium wire armour. Aluminum/Steel Tapes applied helically over the bedding of multi-core cables as per IEC 60502.
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 such as LLDPE, MDPE, HDPE, LSF, CPE are available on request.
