LT PVC Power cable

brand, PVC insulated LT Heavy Duty cables are as per IS:1554 (Part-1) 1988 and are suitable for fixed installations. CONDUCTOR : The most acceptable metals for conductors are copper and Aluminium due to their higher conductivity and ductility. As copper has got higher affinity for sulphur, it corrodes in the atmosphere where sulphur fumes are present. In these conditions tinned copper should be used. Aluminium oxide film which is always present on Aluminium conductor surface acts as a barrier and it protects the Aluminium conductor form corrosion in fumes laden atmosphere. INSULATION : The PVC covering over Conductor is called insulation and is provided by extrusion process only. The insulated conductor is called core. IS: 1554 permits two types of PVC insulation as Follows : 1) Insulation with TYPE A PVC Compound as per IS: 5831 which is suitable for 70
