Types of Conductors

Conductors are mainly made up of Copper, Aluminium and their alloys. Stranded Conductors Greater flexibility and mechanical strength than the single wire of same crossectional area. Total number of conductor is a strand of n layer = 1 + 3n(n + 1) Overall diameter of stranded conductor = (2n + 1)d where, d = diameter … Read more
