The types and characteristics of mica products as insulating materials

Various types of mica products have excellent phenolic rod, so they are also insulating materials, and the kinds of products are also many, the production process and performance characteristics are so different, but also need to further distinguish. After mastering this knowledge, we have a deeper understanding of the insulation material.
One is a soft mica plate, it is a plate-like transformer pressboard, is bonded with adhesive tape mica or adhesive with mica adhesive in single or double-sided reinforcement material, made by baking, the general Used in motor slot insulation and turn insulation. Under normal circumstances, the soft mica board area will not be less than 400 × 600mm ², and requires a neat edge, adhesive distribution even; do not allow impurities, stratification and other undesirable phenomena.
The other is mica plate, is a different hardness of the insulation material, but in any case, they have excellent high temperature insulation properties, but also in high temperature insulation materials, has a good price; at the same time there are excellent electrical insulation Performance and bending strength and processing performance.
There is also a epoxy fiberglass tube, it is made of hard plate-like insulation material from the gasket, gasket, pad or other special-shaped pieces. When it is normal, this kind of insulating material has good mechanical strength and electrical performance, suitable for a variety of electrical appliances, welding machines, arrester, electric components such as gasket insulation.
There are also mica tubes and mica tapes, the former is a rigid tubular insulation material, mainly by the stripping mica or mica paper with the appropriate adhesive bonding in the single-sided reinforcement material from the rolling; the latter is the band of insulation material. In addition, the commutator mica board is a special insulation material, specifically for the working temperature of 130 ℃ DC motor commutator between the copper insulation design.
