The Company
Leeds Transformer Company was established in 1947. It has, since then specialised in the manufacture of bespoke, custom build, low loss, energy efficient, high
quality transformers and transformer rectifiers. These are designed and built with pride by our dedicated,
highly skilled team at our works in Leeds,West Yorkshire,England.
Our transformers and rectifiers range from 1 to 550KVA and are built to British and International standards with, short lead times, quality assurance traceably
and conforming to the BS EN ISO 9001:2008 Standard, and if needed, documentation (Quality and Technical IOM Manuals with AutoCAD drawings).
Liasing with consulting engineers and specifiers to produce the 'right answer' for the project.
