Design and Manufacture Technology of Polymer Bushing for Pole Mount Transformer

Recently, polymer insulator and bushing that are used for high voltage application have some advantages such as light weight, small size, vandalism resistance, hydrophobicity and easy making process. The pole mount transformer installed in distribution system is acting direct role in supply of electric power and the electric power device should drive safely for long tenn. In this paper, the polymer bushing of pole transformer is designed adaptively to current assembly method, designed bushing is manufactured on basis of that result. The electric field of designed transformer is investigated by FEM program.
