Cast Resin Dry Type Transformers

Emirates Transformer & Switchgear manufacture a complete range of high-quality IEC Standard 36kV voltage class ground-mounted Cast-Resin type distribution transformers. Our standard ratings start at 100kVA and go up to 15MVA, they are designed to comply with industrial and commercial indoor technical applications. 

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.

Cast-resin dry-type transformers are designed for indoor applications where transformers using hydrocarbon-based (mineral oil) dielectric fluid mediums are not permitted due to the higher fire risk to people and property. Due to the reduced fire risk, the installation of fire blast walls &/or deluge systems is greatly reduced and no transformer fluid containment system is necessary.

Offering lower maintenance regimes, they are ideal for tropical humid climatic conditions that occur in hot climates. Whether the requirements are from distribution to excitation type transformers we are able to support your specification and application needs. Offering high operational performance properties in terms of low losses, low partial discharge, high electric strength, high overload capacity, and excellent sound isolation available in bespoke metal-clad outer enclosure.
