INTRODUCTION

The Rigid Mica tubes made by the high grade thin mica plate, white mica paper or phlogopite mica paper with the silicone resin which has the excellent mechanical strength and electrical properties.

It is used as supporting insulation for electrode bar or bushing line in motors, electric smelt metal oven and so on.
