Product Q&A

Q:How to select transformer capacity?

Generally select 1.2-1.4 times the load power with margin for expansion. High overload transformers allow lower nameplate rating, using overload capability for peak demand while reducing demand charges.

Q:Difference between oil-immersed and dry-type transformers?

Oil-immersed offers strong overload, good cooling, lower cost for outdoor/heavy industry; dry-type offers better fire resistance for indoor/high-safety applications. High overload transformers are typically oil-immersed.

Q:How to reduce transformer losses?

Reduce no-load losses with high-permeability silicon steel and optimized magnetic circuit; reduce load losses with oxygen-free copper and optimized winding structure. High overload transformers are optimized in both aspects.

Q:What is transformer overload capability?

The ability to withstand loads exceeding rated capacity for short periods. High overload transformers typically offer 50-60% extra load or long-term operation at 110% voltage. Duration is limited by winding hot-spot temperature.
