About Mica Tube - High Quality Electrical Insulation

Mica Tube High Quality Electrical Insulation

Product Overview

A Mica Tube is a cylindrical insulating component made by winding or molding high-grade mica paper or mica sheets, often bonded with resins (silicone, epoxy, or shellac). Known for their superior dielectric strength, high-temperature resistance, and mechanical durability, mica tubes are a trusted choice in high-voltage and high-temperature electrical applications.
