Product Q&A
Q:What standard specifications and type tests does this 220kV transformer meet?
A:
This transformer is manufactured under a strict ISO9001 quality system and complies with high-voltage utility manufacturing codes. It has fully passed the complete National Authoritative Type Test, including the sudden short-circuit (SC) withstand capability test, ensuring mechanical and thermal stability under grid faults.
Q:What cooling methods and tap changer options are available for this series?
A:
The transformer features an oil-immersed design equipped with heterotypic radiators and internal baffle plates for directed oil flow. It supports both ONAN (Oil Natural Air Natural) and ONAF (Oil Natural Air Force) cooling. For voltage regulation, it can be configured with either an On-load Tap Changer (OLTC) or an Off-circuit Tap Changer.
Q:Can the vector group and voltage ratios be customized based on our local grid specifications?
A:
Yes. Our factory operates on a fully custom, order-driven engineering workflow rather than standard stock. We support standard vector groups such as YNd11 and YNyn0d11, and we evaluate and customize specific voltage ratios (e.g., 220kV down to 10.5kV, 11kV, or 35kV) and rated MVA capacities strictly based on your provided schematic layouts, circuit diagrams, and technical BOMs.
