TBEA Hengyang Transformer

The dedicated English profile names TBEA Hengyang Transformer Co., Ltd. and gives Baishazhou, Hengyang, Hunan, as its address. That entity-specific profile is the basis for the equipment ranges on this page. It is more precise for a quotation than a general TBEA group brochure covering other manufacturing locations and businesses.

Name the Hengyang entity in the request and ask the offer to identify the proposed manufacturing location. If a package includes components or services delivered by another entity, request a responsibility schedule for them. A consistent entity and site reference across the quotation, design documents and acceptance plan helps the purchaser evaluate the actual supply rather than the breadth of the group brand.

Hengyang's published 10–1,000 kV envelope covers transformers and reactors. It is an equipment-family range, not one model available in every possible combination of voltage, rating, cooling and impedance. Begin an AC enquiry with the station single-line diagram and the duty assigned to the transformer or reactor.

For a transformer, identify winding voltages, MVA ratings, regulation and cooling requirements. For a reactor, identify its role in the system and the required operating conditions. Ask the supplier to provide the proposed equipment's design schedule and inspection requirements. Keep the selected equipment and its electrical duty visible in the comparison, rather than comparing two offers solely by the top voltage shown in each catalogue.

Hengyang lists mobile substations at 33–380 kV. A mobile installation needs a deployment brief alongside the electrical specification: the required station duty, transport arrangement, site access and connections. Ask for the proposed equipment arrangement and the responsibilities for deployment and handover to be identified in the offer.

The dedicated profile also lists pad-mounted transformers, high- and low-voltage switchgear, high-voltage switches and automation/protection systems. An enquiry for a complete station should distinguish these components from a transformer-only order. Attach the single-line diagram and indicate which protection, control, metering and auxiliary interfaces the package must include.

For a replacement or expansion, include the existing drawings and the interfaces that must be retained. For a new package, ask for a component schedule and an overall acceptance plan. This makes it possible to compare an equipment-only offer with an integrated supply while accounting for the work that each leaves to the purchaser.

The company's introduction includes power-project EPC, substation operation and maintenance, and investment, construction and O&M services for storage and renewable-energy charging stations. Ask for the contractual boundary of a project offer: equipment supply, design, construction, commissioning and ongoing service can be assigned separately.

The Hengyang government reported in November 2023 that TBEA Hengyang was named a demonstration enterprise in the fifth service-oriented manufacturing list. The report describes innovation across transformers, secondary protection, high-voltage switches and distribution equipment. This is a dated organisational recognition relevant to its service scope; model-specific performance and testing still belong in the equipment's technical agreement.

For a new transformer order, request capacity, no-load loss, load loss and impedance with the proposed winding arrangement, cooling stage, tap position and reference conditions. Include the purchaser's loss-evaluation method so that the technical and commercial comparisons use the same duty. Do not apply a guarantee from an AC design to a converter-transformer or mobile-station proposal simply because both carry the Hengyang name.

Define design review, factory witness points, shipment and site handover in the initial brief. Ask for serial-number-linked factory records and a responsibility schedule for accessories, transport and installation activities. For a maintenance contract, identify the returned asset and its acceptance programme separately. Keep the enquiry and the follow-up documentation connected through this platform so the agreed equipment or service scope remains easy to review.
