Frequently Asked Questions
What is a 35kV oil immersed power transformer used for?
It is mainly used in medium-voltage transmission and distribution systems to step down or step up voltage between substations and end users.
Why choose oil immersed type instead of dry type?
Oil immersed transformers usually offer higher capacity range, better cooling performance, overload capability, and lower initial cost for outdoor applications.
Can you customize voltage ratio?
Yes. We can customize HV/LV voltage ratio, tap range, vector group, frequency, and accessories.
Do you support OEM branding?
Yes. Nameplate, logo, painting color, packaging, and documents can be customized.
