Conductors & conducting materials

Conductor is a physical medium to carry electrical energy form one place to other. It is an important component of overhead and underground electrical transmission and distribution systems. The choice of conductor depends on the cost and efficiency. An ideal conductor has following features. It has maximum electrical conductivity. It has high tensile strength so that it can withstand mechanical stresses. It has least specific gravity i.e. weight/unit volume. It has least cost without sacrificing other factors. BAPL has capability to test 1)Aluminum conductor for overhead transmission purposes, Aluminum Stranded Conductors as per IS 398 (Part 1): 1996. 2)Aluminum Conductors for Overhead Transmission Purposes - Aluminum Conductors, galvanized steel-reinforced as per IS 398 (Part 2): 1996. 3)Aluminum Conductors for overhead transmission purpose (Aluminum Conductors, Aluminized Steel Reinforced) as per IS 398 (Part 3): 1976. 4)Aluminum Conductors for overhead transmission purpose (Aluminum Alloy Stranded Conductors) [Al. – Magnesium –Silicon Type] as per IS 398 (Part 4): 1994. 5)Aluminum Conductors – Galvanized Steel – Reinforced for extra high voltage (400 kV & above) as per IS 398 (Part 5): 1992. 6)Wrought Aluminum and Aluminum Alloy bars, Rods, Tubes, Sections, Plates and Sheets for Electrical applications as per IS 5082: 1997. 7)Copper rods and bars for Electrical Purposes as per IS 613: 2000. 8)Copper Strip for Electrical Purposes as per IS 1897: 2008. 9)Conductors for overhead lines Round Wires concentric lay stranded conductor as per BS EN 50182: 2001.
