 Introduction

Transformer Bushings(Bushing Insulators& Wall Bushings) have many advantages such as the oil-free, gas-free, porcelain-free, explosion-proof, eco-friendly, maintenance-free and strong ability of anti-pollution flashover, etc, needless to say, they are the ideal substitutes of traditional oilpaper electric capacity type transformer bushings.
