Alliance Engg. Co.

A primary current injection set is a device that injects high electric currents into electrical systems to test and maintain them.

We manufacture Transformer oil filter machine from 500 LPH  to 8000 LPH : Designed for efficient purification of transformer oil, our high-vacuum, single-stage filtration machine removes moisture, gases, and impurities, enhancing dielectric strength and ensuring long-lasting transformer performance.
Equipped with a powerful vacuum pump, multi-stage filtration, and advanced heating system, this machine meets industry standards for both new and in-service oil conditioning. Ideal for reliable transformer maintenance and oil reconditioning.

We also undertake transformer oil filtration job at our premises.
