Various Types of Insulators Used in Power System for Safe Operations of the Transmission Lines
Publication Date : 01/04/2016
Overhead bare conductors on steel towers or concrete poles are utilized in transmission and distribution of bulky electric power. These conductors are bare and do not have any insulated coating over them. To ensure safe operation of the lines, a necessary clearance between metal structure in case of tower and bare conductors, insulators are mounted. Insulators provide support to the bare conductors and also provide insulation of high voltage conductors with metal structures. In this paper, the importance of insulators in power system transmission is discussed along with the structure, operational principle, types, failure, choice of insulators and recommendations proffered.
