[0002] Mica tube pipe is a hard tubular insulating material made of peeled mica or mica paper with appropriate adhesive bonded to a single-sided reinforcement material and rolled. Mica tube has good electrical insulation performance and high mechanical strength. It is suitable for the insulation of electrode rods or outgoing mica sleeves in various electrical appliances, motors, electric smelting furnaces and other equipment. Compared with traditional ceramic tubes, it has the characteristics of easy control of wall thickness and taper, uniform discharge, and not easy to break. It is an ideal substitute for some ceramic tubes.

[0033] Working principle: When the device is in use, the mica tube body 1 is divided into three layers, namely, the inner tube 2, the middle tube 3 and the outer tube 4. When the mica tube body 1 is processed, a fiber mortar layer 51 is arranged in the inner tube 2.
