Production Introduction
Polymer Insulated Bushings for Transformers
Products Description
What is a polymer bushing?
These polymer bushings are manufactured with a woven structure, using PTFE and epoxy resin. This design delivers tensile strength far exceeding that of injection-molded polymer bushings, while offering superior resistance to heavy loads, seizure, and galling. They are ideal for high-speed applications involving rotation or oscillation.
