Impregnation System for Electric Machines
It consists in a system, 100% solids, for the coating of traction engine armatures, generator armatures, stator field coil windings and for electric machines in general.
The system has three components which are easy to stir-mix and have a good working life (pot-life), which allows smooth application regardless of the size of the machine or the coil to be impregnated.
Blending ratio: (Part in weight)
It is better to prepare the blend at room temperature, first by adding the accelerator to the resin, and then the hardener. If a shortened preparation time is desired, the amount of accelerator can be doubled.
Usage time at room temperature is 12-14 hours for 0.5 kg preparations.
