Insulating Varnish For Electric Motors

They are solvent based so they dry quickly.

Insulating varnish for electric motors.

This insulation protects the windings from contamination shorting electrically and also make the windings more mechanically rigid. This low viscosity one part varnish coating is easy to use and adheres well to many substrates. The finest in insulating varnishes and impregnating resins ensure your electric motors generators transformers and sensors will function properly and reliably. The life of a winding depends upon keeping it in its original condition as long as possible.

Electrical insulating varnish. After a motor is rewound the windings must be further insulated with resin or varnish. Applications usages the 4228 insulates transformers coils armature motor windings and various electric. Our 4228 red insulating varnish is a highly insulating coating with excellent arc and corona resistance.

It replaces insulating varnish enamel mica etc. From environmental protection moisture and dust to added strength varnish and resin support proper motor function and help prevent motor system failure. Jyoti 141 fd an electric insulating air drying varnish based on modified polyester resin. 78 is an ideal electrical refractory cement for coating resistors coils electric heating elements furnaces and embedding resistance wire.

In a new machine the winding is snug in the slots and the insulation is fresh and flexible and has been treated to be resistant to the deteriorating effects of moisture and other foreign matter. Sauereisen electric resistor cement no. There are four types of varnishing methods that we will describe below. About product and suppliers.
