Insulating Varnish For Electric Motors

78 is an ideal electrical refractory cement for coating resistors coils electric heating elements furnaces and embedding resistance wire.

Insulating varnish for electric motors.

After a motor is rewound the windings must be further insulated with resin or varnish. The cement is also available in powder form known as. 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. Jyoti 141 fd an electric insulating air drying varnish based on modified polyester resin.

The old dip and bake in varnish method of insulating motors is replaced by the vpi process for specific reasons. Slot insulation and wedge. Spray these abrasion and wear resistant coatings on motor winding wire transformers and other metal electrical parts to protect them from oils chemicals and moisture. Vpi vacuum pressure impregnation is a process that is a technological step forward from varnishing electric motors.

The finest in insulating varnishes and impregnating resins ensure your electric motors generators transformers and sensors will function properly and reliably. From environmental protection moisture and dust to added strength varnish and resin support proper motor function and help prevent motor system failure. 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.

Improved efficiency through better heat transfer improved mechanical winding design. This low viscosity one part varnish coating is easy to use and adheres well to many substrates. The life of a winding depends upon keeping it in its original condition as long as possible. In electrical machines jyoti 141 fd used both for manufacturing and repairing the following thermal class h 195 objects.

Dip and bake epoxy varnishing trickle varnishing vacuum pressure impregnation and. They are solvent based so they dry quickly. Cleaning and varnishing of machine windings. Sauereisen electric resistor cement no.

About product and suppliers. This insulation protects the windings from contamination shorting electrically and also make the windings more mechanically rigid. It replaces insulating varnish enamel mica etc.
