Power Transformers

Emirates Transformer & Switchgear manufacture a range of high-quality IEC Standard ≤72kV medium power transformers. Our range covers 6 to 30MVA. Designed and manufactured utilising high-quality materials and production procedures to deliver a superior and reliable transformer that exceed the requirements of electrical utility substation applications. 

ETS’s transformer technology is derived from over 30 years of design and manufacturing excellence in our ‘world-leading’ facilities in Europe, the Middle East, and Africa. Our manufacturing principles and processes exceed internationally recognised standards to ensure that only highly reliable and resilient transformers are connected to critical electrical networks. Fully optimised designs meet customer’s unique requirements for loss limitation, harmonics, physical size, and weight to deliver total engineered and reliable solutions for a broad range of applications.

Transformer designs are proven with a significant installed base applied in temperate, extreme and harsh condition environments I.E. extreme high temperatures, humid and tropical climates. This makes our product the product of choice for electrical utilities and large industrial operators. Whether the requirements are for ONAN/KNAN or ONAF/KNAF type transformers we are able to support your specification and application needs.

Offering high operational performance properties in terms of voltage ratio, losses, impedance temperature rise, and optimised transformer layout or footprint.
