Liaocheng, China​ — Liaocheng Xinda Transformer Co., Ltd. has been officially listed as a winning bidder in the third-round public notice for the procurement project of synthetic testing equipment for new-type converter equipment, issued by the China Southern Power Grid (CSG) Unified Supply Chain Service Platform on behalf of the New-Type Power System Research Institute (Beijing). Xinda Transformer secured the converter transformer supply package​ after outperforming multiple industry competitors, demonstrating its solid R&D capability, stringent full-process quality control, and proven project delivery track record.

This award represents the highest-level authoritative recognition from CSG of Xinda Transformer’s product quality, core technology, compliance management, and comprehensive service capability. It marks the company’s formal entry into CSG’s core qualified supplier roster and its successful admission into China’s advanced power equipment procurement supply chain — laying a premium cooperation foundation for deeply participating in the national new-type power system buildout and supporting the country’s high-quality energy development.

A Landmark Milestone in the HVDC Converter Equipment Supply Chain

As a super-large central state-owned enterprise safeguarding national energy security and underpinning national economic development, CSG operates one of the most demanding and highest-value procurement platforms in China’s power equipment sector. Its bidding evaluation is benchmarked against the most rigorous industry standards, enforcing the strictest review criteria across every dimension — technological innovation, precision manufacturing, quality management systems, compliance and credit qualification, work safety standards, and full-lifecycle after-sales service. The competition is fierce, with an exceptionally high elimination rate.

Successfully passing CSG’s multi-tier screening and stringent qualification verification serves as an all-dimensional, authoritative certification of Xinda Transformer’s comprehensive hard power, market reputation, and industry competitiveness.

What This Win Means for Xinda Transformer

Securing the converter transformer supply package in CSG’s new-type converter equipment project delivers three strategic outcomes:

• Supply Chain Elevation​ — Formal inclusion in CSG’s core qualified supplier sequence, unlocking access to subsequent high-voltage and extra-high-voltage tenders.
• Technology Validation​ — Independent verification that Xinda’s converter transformer technology meets the most stringent HVDC application requirements for insulation, thermal performance, and reliability.
• Brand Authority​ — Third-party endorsement from China’s most demanding grid operator, significantly strengthening the company’s credibility in both domestic and overseas markets.

Enabling the New-Type Power System

The converter transformer is a core piece of equipment in high-voltage direct current (HVDC) transmission systems, responsible for linking the converter bridge to the AC grid and providing a neutral-point non-grounded three-phase commutation voltage. With this award, Xinda Transformer is now positioned to contribute directly to China’s new-type power system construction, delivering converter transformer solutions that meet the evolving demands of renewable energy integration, grid flexibility, and ultra-long-distance HVDC transmission.

As a national high-tech enterprise headquartered in Liaocheng, Shandong Province, Xinda Transformer specializes in the R&D, manufacturing, sales, and service of power transformers and complete transmission & distribution equipment. The company’s product portfolio spans oil-immersed transformers, dry-type transformers, special-purpose transformers, and prefabricated substations, serving power, new energy, and industrial & mining sectors across China and export markets in Central Asia and Southeast Asia.
