Hi Guest! Welcome to FARHAN HEAVY ELECTRICALS

To obtain optimum performance from transformer, it requires high quality and purity of insulating oil during the time of use for all present and future transformer. The increasing voltage and rating of the modern transformer under goes greater electrical stress in insulating material and fluids of electrical apparatus. To avoid these stresses, oil with good dielectric qualities and minimum residual moisture (water) content in oil should be maintained.

Contaminated oil tends to lose its characteristics of dielectric strength, resistivity and loss factor. Moisture in oil, favours acid and sludge formation.

The farhan insulating oil treatment equipment has been designed specifically for the filtration, dehydration and degassing of the insulating oils used with transformers, electric cables, switch gears etc.
