Epoxy polyester air dry insulation varnish 9120 is suitable for surface covering of steam turbine generators, hydro generators, AC/DC motors, and other electrical appliances. For generators, insulation varnish can effectively increase their insulation strength and prevent moisture, pollution, or short circuits. At the same time, the film layer it forms can provide a certain degree of mechanical protection, reducing the damage caused by external forces and vibrations to electrical equipment.

The application of insulation varnish 9120 is extensive. There are many locations on the generator where insulation varnish can be used, including:

1. 1. Winding: The generator winding is the core component through which current flows. The use of varnish 9120 can provide insulation protection for the winding to prevent electrical equipment from moisture, short circuits, or pollution.
2. 2. End insulator and coil head: The generator winding end requires additional insulation protection. The use of insulation varnish 9120 can form a uniform and dense insulation layer, enhancing insulation performance.
3. 3. Insulation piece and sleeve: The insulation piece and sleeve are commonly used to isolate components of different voltage levels. Insulation varnish 9120 is used to protect the piece and sleeve, enhancing insulation performance.
4. 4. End cover: The generator end cover is a key part of the enclosed rotor and stator, covered with insulation paint such as varnish 9120 or red porcelain paint 188, which can protect the end cover and end cover bolts from pollution and corrosion.
