Project Description:
AISITE is pleased to announce the successful delivery and port arrival of a custom-engineered 12MVA (12,000kVA) oil-immersed power transformer for a significant ground-mounted solar photovoltaic (PV) power plant project in Southeast Asia. Completed and shipped in July 2025, this critical piece of equipment is now prepared for installation and commissioning. Designed as the heart of the plant's step-up system, this transformer plays a vital role in efficiently and reliably elevating the voltage of solar-generated electricity for seamless integration into the regional power grid.

Project Highlights:
Precision Customization for Solar Applications:
This transformer was specifically engineered for the demanding environment of solar PV plants, taking into account common characteristics like power fluctuation and harmonic content.
The 12MVA capacity was precisely calculated based on the client's actual installed generation capacity and grid interconnection requirements, aiming for optimal system compatibility and operational efficiency.
AISITE's engineering team worked closely with the client to meticulously confirm and tailor key specifications, including electrical parameters (e.g., impedance, losses), cooling system design, robust protection rating (IP55), and interface dimensions, ensuring smooth integration into the existing plant infrastructure.
Rigorous Quality Control & Proven Manufacturing:
Leveraging 15 years of specialized transformer manufacturing expertise, AISITE adheres strictly to ISO 9001 quality management principles throughout production.
Stringent quality control protocols were applied at every stage, from sourcing premium core materials to executing critical processes like precision coil winding, core stacking assembly, vacuum drying, and vacuum oil filling.
Comprehensive routine and type tests were performed prior to shipment, including no-load, load, temperature rise, lightning impulse, and partial discharge tests. This rigorous approach is designed to ensure high reliability, enhanced efficiency (low-loss design), extended service life, and robust electrical performance, meeting the design requirements of international standards like IEC 60076.
Efficient Collaboration & Responsive Communication:
A hallmark of project execution was the efficient internal communication and timely feedback between AISITE's sales team, technical engineers, and production workshops.
During the critical technical drawing approval phase, customer inquiries and reasonable modification requests were typically addressed promptly. Clear technical feedback and updated documentation were typically provided within a short period of time (e.g., 24-48 hours), demonstrating AISITE's commitment to accuracy and customer satisfaction.
This responsive communication model effectively ensured alignment between production plans and customer expectations.
On-Time Delivery Commitment Fulfilled:
Navigating complex international logistics, AISITE utilized its extensive export experience to meticulously plan the transportation strategy to ensure the power equipment arrived at the project site on time.
The oil filled transformer was completed, tested, and safely delivered to the destination port as planned in July 2025, providing strong support for the solar plant's target grid connection timeline.

Support Capabilities:
AISITE transformers have been successfully deployed in over 50 countries and regions worldwide, including notable projects in Tanzania, Brazil, and Saudi Arabia across power, industrial, and renewable energy sectors.
For this project, AISITE stands ready to provide comprehensive support, including on-site installation supervision, commissioning services, and operator maintenance training as needed by the client to facilitate smooth start-up and support long-term, stable operation.
Conclusion:
The successful delivery of this 12MVA oil-immersed transformer for the Southeast Asian solar project underscores AISITE's strengths in the power equipment sector: deep technical expertise, effective customization capabilities, a commitment to quality management, and proven project execution. AISITE is dedicated to providing global clients, particularly those in the rapidly growing renewable energy field, with high-performance, reliable transformer solutions backed by comprehensive support services.
