We’re industry experts in Transformers

Blakley Electrics designs and manufactures wide range of power transformers in ratings ranging from 100VA to 250kVA and in voltages from 12 volts to 3300 volts.

Our transformers are generally double wound, enclosed in a steel or insulated enclosure, usually offering high levels of ingress protection.

Assemblies are manufactured to our own exacting standards and come equipped with all necessary switchgear and distribution equipment, as required.

We are approved suppliers of transformers to organisations such as BAA, BNFL, London Underground and Network Rail.

We stock a wide range of standard industrial and construction site transformers, manufacture bespoke units for specific industries and applications and design to customer specific requirements.
