Insulating Varnish For Electric Motors

The finest in insulating varnishes and impregnating resins ensure your electric motors generators transformers and sensors will function properly and reliably.

Insulating varnish for electric motors.

It replaces insulating varnish enamel mica etc. There are four types of varnishing methods that we will describe below. Jyoti 141 fd an electric insulating air drying varnish based on modified polyester resin. The cement is also available in powder form known as.

The old dip and bake in varnish method of insulating motors is replaced by the vpi process for specific reasons. Electrical insulating varnish. 78 is an ideal electrical refractory cement for coating resistors coils electric heating elements furnaces and embedding resistance wire. Dip and bake epoxy varnishing trickle varnishing vacuum pressure impregnation and.

This low viscosity one part varnish coating is easy to use and adheres well to many substrates. Improved efficiency through better heat transfer improved mechanical winding design. After a motor is rewound the windings must be further insulated with resin or varnish. Vpi vacuum pressure impregnation is a process that is a technological step forward from varnishing electric motors.

Sauereisen electric resistor cement no. This insulation protects the windings from contamination shorting electrically and also make the windings more mechanically rigid. In electrical machines jyoti 141 fd used both for manufacturing and repairing the following thermal class h 195 objects. Cleaning and varnishing of machine windings.

About product and suppliers. From environmental protection moisture and dust to added strength varnish and resin support proper motor function and help prevent motor system failure. 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. Our 4228 red insulating varnish is a highly insulating coating with excellent arc and corona resistance.

They are solvent based so they dry quickly. Applications usages the 4228 insulates transformers coils armature motor windings and various electric. Slot insulation and wedge.
