Distribution Liquid Transformers

Emirates Transformer & Switchgear manufacture a complete range of high-quality IEC Standard 11kV and 33kV voltage class liquid-cooled pole and ground-mounted distribution transformers. Our standard ratings start at 50kVA and go up to 4000kVA, they are designed to comply with the exacting technical demands of Electrical Distribution Network Operators worldwide.

ETS’s transformer technology is derived from over 30 years of design and manufacturing excellence in our ‘world-leading’ facilities across Africa, Europe, and the Middle East. Our manufacturing principles and processes exceed internationally recognised standards to ensure that only highly reliable and resilient transformers are connected to critical distribution networks.

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, industrial, oil, and gas operators.

Whether the requirements are for breathing conservator or hermetically sealed 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.
