175 MVA, 138 kV Power Transformers for a Texas Data Center Project
Changzhou Sieyuan Toshiba Transformer Co., Ltd. (CST) supplied 175 MVA, 138 kV power transformers to a data center project in Texas, USA. Designed and manufactured in accordance with IEEE standards, the transformers meet the requirements of North American 60 Hz power systems and support the continuous high-load operation demands of data center infrastructure. Through flexible engineering coordination, optimized manufacturing processes and efficient project execution, CST achieved a five-month fast-track lead time on an FOB basis, supporting the project's accelerated construction schedule.

Project Overview
Project Background
The rapid growth of data centers has increased demand for reliable, high-capacity power infrastructure. This project required high-voltage transformers with strong operational reliability, flexible engineering adaptability and compliance with North American utility standards. During project execution, major parameter adjustments were introduced, requiring rapid technical evaluation and implementation while maintaining the original project schedule.
Key Challenges
Tight delivery schedule — The project required complete transformer design, manufacturing, testing and shipment within a compressed timeframe to support the data center construction schedule.
Flexible response to design changes — Major parameter changes during execution required rapid technical evaluation, design verification and coordinated implementation without affecting project progress.
Strict IEEE compliance requirements — The transformers required full compliance with IEEE standards, including verification of insulation performance, losses, partial discharge and temperature-rise characteristics.
Sieyuan Solution
Integrated project execution — CST established a cross-functional project team covering engineering, manufacturing, procurement, quality and export logistics, with a coordinated communication mechanism enabling rapid response to technical changes and project requirements.
Optimized design and manufacturing process — For major design adjustments, CST conducted electromagnetic, structural, temperature-rise and insulation verification in parallel with engineering document updates, leveraging a mature IEEE-compliant product platform to shorten the design cycle, reduce redesign efforts and maintain schedule stability.
Accelerated production and testing — Production processes for key components, including the core, winding, tank and insulation systems, were optimized through parallel scheduling, with comprehensive IEEE standard tests completed to verify performance before shipment.
Technical Highlights
IEEE-compliant transformer design — The transformers were designed and tested according to IEEE requirements, meeting North American 60 Hz grid conditions and the reliability requirements of data center power infrastructure.
High flexibility for project changes — The project execution approach enabled rapid evaluation and implementation of major parameter adjustments while maintaining the committed five-month FOB lead time.
Reliable long-term operation for data center infrastructure — Comprehensive factory testing, including insulation, loss, partial discharge and temperature-rise tests, verified transformer performance for continuous heavy-load operation and long-term reliability.
