Installed close to low-voltage devises, a molded transformer is the only means of designing optimized equipment that reduces loss from voltage drop in the electricals.
ABB, whose molded transformer YG-TOMS provides, is the world’s leader in transformer technology that has supplied over 100,000 dry transformers worldwide from its specialized and large-scale production facilities, and owns a wide-range of specialist technology related to molded transformers.
· Characteristics
- Small area required for installation and reduced total cost.
- Pollution-free and fire-fighting facilities not required.
- Convenient maintenance and insulating oil not required.
- Eco-friendly and safe / flame retardant and no risk of fire.
- High short-circuit strength and excellent overload capacity.
