Polycab 16 Sqmm 4 Core PVC Sheathed Copper Flexible Cable

This standard covers the requirements for both armoured and armoured single, twin, three, three and half, four, and multicore cross-linked polyethylene (XLPE) insulated and PVC sheathed cables for electric power supply purposes. These are low tension cables of voltage grade up to and including 1100V AC. These cables may be used on DC system for rated voltage up to and including 1500V to earth. These are widely used for power distribution in external and direct burial applications in power network system, underground and cable ducting. Technical advantages: 1.Higher Current rating, higher short circuit rating. 1.2 times that of PVC 2.Insulation is thermosetting in nature. 3.Higher insulation resistance 1000 times more than PVC cables. 4.Higher resistance to moisture. 5.Better resistance to surge currents. 6.Low dielectric losses. 7.Better resistance to chemicals. 8.Long service life. 9.comparatively higher cable operation temperature 90°C and short circuit temperature 250°C. Conductor: High conductivity annealed plain stranded compacted copper /Aluminium conductor produced in-house from state-of-the art machine. Insulation: In-house developed high insulation resistance cross-linked polyethylene thermoset insulation compound. Laying Up: In case of multi core, insulated cores are laid up together with in-house developed fillers to maintain circularity of cable, wherever applicable. Inner Sheath: In-house developed PVC thermoplastic compound/ halogen free compound having low emission of smoke and corrosive gases when exposed to fire and also ensures circular shape of cable. Armour: Aluminium / Galvanised Steel Round/stripe wire Armoured to give mechanical protection and also acts as return path for earth fault current Outer Sheath: In-house developed PVC thermoplastic compound/ halogen free compound having low emission of smoke and corrosive gases when exposed to fire for outer protection
