Tianwei Baobian (Hefei) Transformer

The company describes AC power transformers and reactors at 750 kV and below, and DC converter transformers for systems at ±500 kV and below. These are different catalogue scope statements. The DC system-voltage notation should not be read as an ordinary AC winding-voltage rating, and the AC upper voltage should not be transferred to every traction or distribution design.

For an AC transformer inquiry, identify the system duty, winding arrangement, voltage ratio, rating and tap requirements. For converter equipment, provide the converter-system specification and interface requirements so that the design and test programme can be agreed with the project. The company also lists railway traction and other special transformers as separate applications, making the intended network and duty central to an offer.

Alongside its higher-voltage scope, the manufacturer lists dry-type, packaged and distribution transformers. The website also has after-sales and repair-business sections. A buyer should therefore identify whether the requirement is a new power transformer, a distribution installation or maintenance of existing equipment, rather than sending the same brief for every category.

For repair, identify the existing transformer, service history and inspection findings so a scope can be discussed. For new supply, request the exact configuration’s capacity, losses, impedance and winding information, together with accessories and site interfaces. The published contact address is No. 58 Honghe Road, Luyang Economic Development Zone, Hefei.

The company website associates its 2004 formation with Baobian Electric. A later corporate record must be read on its own date and scope: China Electrical Equipment Group’s 2025 financial-statement notes, disclosed through the Shanghai Stock Exchange in April 2026, name the Hefei company among entities added to consolidation through a transfer without consideration.

This distinguishes the manufacturing entity from a historical website description. For an order, confirm the named contracting manufacturer and responsible service organisation. Group-level disclosure can establish a dated corporate record; it does not supply model-specific performance data or establish which factory produced an unidentified transformer.
