Manufacturing Enterprise "Yudzhen" is a private enterprise that was founded in 1993 as a limited liability company – manufacturing enterprise "Dipol". In August 2007 the enterprise was renamed as "Yudzhen". The main kind of activity is manufacturing toroidal transformers. The staff numbers over 100 employees. The enterprise has its own production facilities, efficient equipment supporting the whole cycle of transformers and inductance coils manufacturing.

We have been manufacturing toroidal transformers for 28 years ensuring stability of declared characteristics and high quality of goods. Currently, our production capacity makes it possible to manufacture 50,000 winding products per month. We never stop at what has been accomplished and keep on developing by designing and introducing new products, techniques, equipment. Flexibility of production allows to supply goods both retail and wholesale in the shortest possible terms. Preparation of series manufacturing of new products takes 2-3 days.

The enterprise has equipment for manufacturing not only of transformers but also of inductors, and high-frequency winding components on toroidal cores with internal diameter of 6.5 mm after winding with a wire of 0.5 mm and with internal diameter of 9 mm with a wire of 1.0 mm. We develop prototype models.

We have experience of product supplies to Russia, the Ukraine, France, Czechia, Poland.

Development and Innovations

At the moment LLC "Yudzhen" is studying the issue of expanding the range of ratings of the produced measuring current transformers of TSP-N-0.66 type. We are planning to start manufacturing the following rating types: 1200/5A, 1500/5A and 2000/5A. Moreover, we are considering the possibility of manufacturing transformers 300/5A and 400/5A of TSP-N-0.66 type instead of TOP-N-0.66 type.

We are studying the feasibility of using aluminum enameled wire instead of copper wire in the structure of toroidal transformers. We are looking for optimal equipment for assembly and aluminium brazing.
