Key Features of PVC Insulated And Sheathed 3 1/2 Core Unarmourd And Armourd Power Cables

• Conductor: Copper conductors are made from high conductivity Copper rods of 8 mm diameter. The rod is drawn to required sizes for the construction of conductors of different areas of cross section conforming to IS:8130-1984.
• Insulation: PVC Compound is insulated over conductor by extrusion process with required thickness of insulation and conforms to IS: 1554 [Part-1]-1988 for PVC insulated cables. PVC insulation, is either of general purpose `type A` PVC compound, suitable for a maximum continuous conductor operating temperature of 70°C, or of Heat resistant `type C` PVC Compound, suitable for a maximum continuous conductor operating temperature of 85"C conforming to requirements of IS:5831-1984.
• Identification of core colors: number of cores 1 for Red, Black, Yellow, Blue, or Natural [Non-pigmented]; 2 for Red and Black; 3 for Red, Yellow and Blue Red, Yellow, Blue and Black and 4 for Red, Yellow, Blue and Black.
• Inner sheath: Single core cables have no inner sheath.
• Armoring: Single core cables for use on a.c systems, are armoured with single layer of nonmagnetic [Aluminium] material. Multi-core armoured cables have either single layer of Galvanized Steel wire Armour or Galvanised steel formed wire [earlier steel strip] applied over inner sheath with left hand lay. Galvanised steel wires and / or formed wires [earlier called strip] conform to IS:3975-1998.
• Outer sheath: PVC outer sheath with improved fire performance as per Category Cl and C2 conforming to the requirements of IS:5831-1984 are available.
• Packing, storage and handling: Cables for power supplies and control panel wirings are always packed in appropriate sizes of strong and seasoned wooden drums designed to withstand long distance transit and preservation in stores.
