Applicable working conditions of different mica tapes

Applicable working conditions of different mica tapes

1. Mica tape for high-voltage motors is suitable for vacuum pressure impregnation (VPI) tapes. It has high mica content, less glue, and medium rubber mica. It can be used as the main insulation of high-voltage motors and has good electrical and mechanical properties; it can meet the requirements of the motor Requirements for the development of high voltage and large capacity. Most car manufacturers use less rubber mica tape.

2. Mica tape for wind power generation is based on mica paper, alkali-free glass cloth for electrical use, polyester film, polyimide film or corona-resistant film on both sides or one side as reinforcement materials, heat-resistant epoxy adhesive or other resistant Thermal resin, suitable for large and medium-sized wind turbines.

3. Less glue mica has a process system completely different from that of multiple tapes, namely the vacuum pressure impregnation (VPI) process, which is an advanced insulation process. It has the characteristics of high mica content, excellent electrical properties, long insulation life, good integrity, excellent heat resistance and aging resistance, thin insulation thickness, good thermal conductivity, effective reduction of motor temperature rise, simple process, and short production cycle. .

4. Mica tape for water and electricity is a ribbon-shaped insulating material made of powdered mica paper as the base material, non-electric alkali-free glass cloth on both sides as the reinforcing material, and bonded with epoxy adhesive. It is flexible under normal conditions and has good electrical and mechanical strength after molding. It is suitable for forming or hydraulic insulation of coils of hydraulic generators and high-voltage motors with a working temperature of 155℃.

5. Polyimide film powder mica tape is an insulating coil made of mica paper and polyimide film after baking, winding and cutting, with heat-resistant epoxy adhesive. Mica tape has good flexibility under normal conditions. After the wound coil is cured by the dipping varnish, it has excellent dielectric properties and high mechanical strength. It is suitable for the main insulation of traction motors with a working temperature of 180-200 and the insulation of various other motors and electrical appliances.
