Impregnation is process of applying a coating or layers of chemically stable liquids to porous surfaces (like casting) or objects with inherent voids (like motor coils) to prevent accumulation of undesired elements like dust, dirt, chemicals or water. Impregnation of objects improves its physical properties and also tends to improve overall parameters of the equipmentcomponent wherein use. For Ex. a varnish impregnated coil improves the overall insulation resistance of the motor and hence the life of the motor is improved.

NACH addresses questions of the coil winding industry and assists setting up equipments in the coil winding industry. NACH pressure-vacuum units for impregnation systems have ensued economical solutions in motor manufacturing and repairing shops in form of flood impregnation. Understanding that the need of rotary machine manufacturing and repair shops is distinct, NACH offers a variety of customized solutions designed to suit different sectors of application.

mproved insulation properties of the oil and hence the other media like papercellulose insulation Better the insulation of transformer, longer the life of the transformer and lesser the breakdown of the transformer Longer the life of the transformer asset, good returns on investment of the asset Lesser breakdowns and failure of the transformer results in uninterrupted power supply

The Transcure BS series are single stage streamline transformer oil filtration machine. Transcure BS series of Transformer oil filter machine is designed to tame oil problems in the LT distribution transformer sector. The practical experience of transformer oil filter machines used for repairing distribution transformer has led to development of TRANSCURE BS series which is dedicated to handle small oil volumes. Typical capacities are 100 LPH ~ 500 LPH; 1000 LPH~2000 LPH, 2250 LPH & 3000 LPH.

Vacuum is drawn in transformer tank with aid of transformer evacuation system to remove moisture and gases from insulationoil. Alternately during commissioning of transformer, nitrogen is evacuated with transformer evacuation system before new oil filling or oil alteration in transformers. Transformer evacuation is a wet process which necessitates proper moisture extraction before its entry into vacuum pump. NACH has designed transformer evacuation systems that have efficient moisture condensers with adequate cooling area that are placed in line with the vacuum pump. In case of non-availability of cold water circulation at site, condensers are also provided with facility of ice cups which aid to hold ice and improve the moisture condensation.
