electric machine mica tape is used for reeling on the coil of electric machinery as insulation materials.
electric machine mica tape is built up with mica as base material and electrical-use alkali-free glass-cloth, polyester or polyemide film as reinforcing material, bonded by binder and formed a tape-like insulation material. It is perfectly flexible under the normal temperature and after reeling on the coil of electrical machinery, may be solidified and has a thin insulation thickness and excellent electrical and mechanical strength.
