Products Dry Type Transformers

Dry Type Transformers

‘Large & small, dry type transformers are the preferred choice for a vast range of applications. ATL have over four decades of expertise in manufacturing high quality dry type transformers to industry’ 

ATL offers a comprehensive range of Copper and Aluminium wound dry type transformers. These are presented in a standard product series as well as bespoke solutions tailored to meet your specific system requirements.

Our continuous search for advances in magnetic’s keep us at the forefront of transformer design and manufacture. We avoid the conventional and push the boundaries of magnetic’s everyday. This is what sets us apart in industry and what has delivered many of our innovations to date.



Dry type transformers are available as isolation, safety isolation as well as auto wound transformers. They are available for a wide range of system topologies and distribution voltages. We offer Single phase, Three phase, Three phase to single phase, phase shifting and harmonic mitigation with our  multi pulse magnetic’s.

ATL manufactures a standard range of dry type transformers up to a power level of 1.5MVA and up to 12kV bracket aligned to IEC 60076 and IEC61558 standards.

The details of our standard series can be provided upon request and ATL’s technical team is available to discuss your bespoke requirements day and night.


Typical Dry Type Product –

Transformer for Event Power.

Step-up /Step down Isolation transformers for the event hire sector. This range deliver critical power to PA and lighting equipment among other functional circuits. With IP56 ratings and manufactured from non corrosive materials this range has to withstand harsh environments and are ran continuously day and night at full power. Our Event Power range offer a high level of reliability with robust constructions and come within heavy duty galvanised crash frames with optional wheels.

Fitted with Primary and secondary pad lockable distribution boxes, Circuit protection, Powerlock connectors and tap selection. This range is also supported with associated Insulated output assemblies and extension leads

ATL’s range of Dry type transformers exceed the requirements of Industry manufacturing standards. All of our dry type transformers go through a specialised process to remove moisture from insulation’s prior to varnish and curing operations. Our unique mechanical construction methods derived over years of practical expearience ensure that under dynamic loading our windings are secure and free from movement throughout the asset life of the product with novel cooling techniques and robust insulation. Our detailed knowledge, experience and innovative culture allow us to provide the best solutions and processes for any given application.
