Products Description
HV Power Transformer
Power transformers are a core component of power transmission system. DB Transformer builds power transformers that deliver power to the consumer efficiently and reliably.
Daelim single-phase and three-phase multi-winding or autotransformers are according to international standards such as ANSI/IEEE /IEC/CSA/AS as well as NEMA standards, etc, the power ratings up to 270 MVA and voltages up to the highest insulation class of 800 kV.
Daelim work relentlessly to exceed the new demands by innovating solutions for a more sustainable and safer work environment with a wide array of electrical transformer solutions for our customers while meeting the most stringent standards. Every transformer is unique, designed according to individual factors such as voltage, power rating, climate, network topography, noise level, and many other criteria.
