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.

In addition to open frame models we offer transformer solutions within our own unique and robust Industrial enclosures. We can service any IP rating requirements from standard indoor IP2X rating, IP5X Outdoor weatherproof applications and submersible solutions. Our swan neck type transformer housing introduced by ATL and now widely duplicated across industry provides a degree of cooling in these naturally cooled dry type transformers while maintaining superior levels of ingress protection.


Our In House Developed Programmes Delivery the Optimum Solution

Decades of experience developing magnetic’s to Industry manufacturing standards ensure that our products deliver high efficiency, long asset life, and ultimately zero failure rates.

ATL’s wealth of industry experience designing custom solutions has built a high level of knowledge used to create our own in house  highly sophisticated design programmes. These programmes give us flexibility within any design while giving customers an economically efficient tailored solution.

Utilisation of these programmes allows us to deliver the optimum design for our clients requirements delivering cost reductions and high levels of efficiency throughout the design.
