Oil Immersed Transformers

Oil Transformers

As defined by IEC60076 standards, distribution transformers are rated up to 2500Kva. Ardan also manufactures larger transformers, you can read more about them in the “Power Transformers” where we go up to 15,000 Kva and up to 36Kv.

Our transformers are fitted for pole mounted design with expansion tank and also for ground mounting with hermetically sealed tanks.

Having quality at the top of our mind, the process of designing and manufacturing each and every transformer is performed to perfection, from the core to the tank, from the coils to the paint you can expect a top workmanship.

Vacuum Drying

Following the assembly of the active part it enters a drying process in a vacuum industrial oven. The moisture in the insulating parts is heated and drawn out of the system to guarantee flawless work of the transformer. After being heated and dried the active part is placed in the tank construction to be filled with isolating fluid.

Whether it is mineral oil or natural ester oils such as Midel eN or Cooper FR3, the transformer are filled under sub pressure environment to assure adequate sealing process.

Quality above all

Each transformer is tested in our laboratory according to IEC 60076 requirements for routine tests. For customers who wish further testing we offer special tests as indicated in the relevant standards. Customers are welcome to witness our lab process and testing facility. Setting world precedent defect rate of less than 0.004%, Ardan is proud in its quality and strongly believe that a job well done is a job done once…
