Oil Cooled transformers
‘Oil cooled transformers with excellent insulation properties and robust enclosures for harsh environmental conditions’
ATL offers a range of oil cooled transformers meeting the requirements of British and European standards and governing environmental legislation. A low loss family of designs offer superior efficiency in line with our strategies to support a greener environment for future generations. In addition to Low loss silicon steels we also present amorphous core transformers available with standard oil or more environmentally friendly MIDEL filled products.
ATL provide solutions for oil cooled transformer requirements both in the areas of standard oil cooled transformers and in the area of bespoke oil cooled transformer requirements. ATL supplies power levels up to 25MVA and voltages up to 33kV. to conventional and bespoke requirements.
Typical products within this range include:
- Distribution transformers.
- Auto-transformers for asynchronous motor starting.
- Oil immersed shunt reactors.
- Earthing transformers.
- Power transformers with DETC and OLTC voltage regulation.
- Power transformers for traction applications, electric drives,Induction furnaces, grid and substation.
