Product Q&A

Q:What is the specification and voltage ratio of this transformer?

Rated capacity: 315kVA, three-phase two-winding oil immersed power transformer. Primary voltage: 11kV / 6.6kV, secondary output voltage: 400V, equipped with OLTC on-load voltage regulation system.

Q:Is this two-winding or three-winding structure?

It adopts standard double winding step-down structure, simple internal structure, low failure rate and easy daily maintenance, commonly used in industrial and municipal power distribution projects.

Q:What frequency does the transformer support?

Standard 50Hz; 60Hz can be customized to meet the power grid requirements of Africa, Middle East and Southeast Asia.

Q:What is the difference between OLTC on-load tap changer and ordinary off-circuit tap changer?

OLTC allows voltage adjustment without power cut during operation. It is suitable for areas with severe grid voltage fluctuation to keep 400V output stable all the time. Off-circuit tap changer must cut off power before regulation, which cannot meet the demand of uninterrupted power supply.

Q:What cooling method and vector group do you adopt?

Cooling method: ONAN oil natural cooling (ONAF air cooling optional for high temperature areas); Default vector group: Dyn11, the most widely used for distribution transformers.
