Dry type or ‘air cooled’ distribution transformers are considered a low maintenance, reliable, and robust solution due to the fact that they have no moving (or serviceable) parts.

Powerstar has manufactured and supplied dry type transformers for a wide range of industrial, commercial & hazardous applications. Due to the reliability, efficiency and long service life of our dry type transformers, they are a great way to maximise your investment.

Unlike their oil-filled counterparts, dry type distribution transformers use only non-toxic, environmentally safe insulation systems, making them more eco-friendly as they pose no oil leak or pollution risk to the environment. The modern insulation systems and materials utilised in these transformers are Class F (155C), H (180C) and C (220C) depending on the applications & size constraints.

We manufacture transformers from 1kVA through 10,000kVA with system volts to 22kV, all systems are built & tested to industry standards (UK) EN60076, (US & Canada) UL506 & 1561, or any customer required standard.

Versatile applications

As we deliver our dry type distribution transformers based on each customer’s requirements in addition to the fact they do not contain oil, there are virtually no restrictions on the installation site. The risk of them creating a fire hazard is minimal, meaning they can be located closer to load, reducing cabling costs and losses. Due to their low flammability, they are widely used for data centres, for inclusion in customer equipment, environmentally sensitive, marine, offshore & hazardous areas.

Dry type transformers can be manufactured so to be suitable for indoor or outdoor applications (an enclosure is provided for outdoor sites with a site-specific IP rating) depending on the characteristics and requirements of your site.
