AISITE Delivers 3000kva Oil-Immersed Transformer for photovoltaic project in Cambodia

I. Project Overview: Deepening Southeast Asian Market Access, Creating a Green Future

A 3000kVA oil-immersed transformer meticulously designed and manufactured by AISITE has recently completed all factory testing and shipment preparations. It officially departed for Cambodia on September 6, 2025. This transformer will serve as core power equipment for a large-scale photovoltaic power station project in Cambodia, aiming to efficiently convert solar energy, provide clean and stable local electricity, and contribute to Cambodia's economic development and emission reduction goals.

The successful delivery of this project is another significant achievement in our company's deep involvement in the Southeast Asian market, fully demonstrating our international customers' recognition of our product quality, technical solutions, and delivery capabilities.

II. Customer Needs and Challenges: Efficient and Stable Operation in a Tropical Climate

Cambodia has a tropical monsoon climate characterized by high temperatures, high humidity, and a long rainy season. The customer placed specific and high demands on the transformer's performance:

High efficiency and energy saving: Low no-load and load losses are required to maximize the return on investment for the photovoltaic power station.

Strong Environmental Adaptability: The device must be able to withstand high temperature and high humidity environments, and the internal insulation system must be extremely moisture-resistant to ensure long-term operational reliability.

Corrosion and Rust Resistance: The housing and components must possess excellent corrosion resistance to withstand erosion from humid air.

Easy Maintenance: The device must operate stably and have long maintenance cycles to reduce ongoing operating costs.

III. Customized Solution

To meet customers' application needs in specialized environments, our technical team provides professional customized solutions.

Advanced, Low-Consumable Materials: The use of high-quality, high-permeability silicon steel sheets and a stepped lamination process effectively reduces iron and copper losses, resulting in energy consumption exceeding energy efficiency standards and significant savings on operating electricity costs.

Enhanced Insulation and Moisture-Proof Design: Designed for high-humidity environments, the insulation material has been specially treated to resist moisture and air bubbles, and a vacuum oiling process is used to completely remove moisture and air bubbles from the device body, ensuring insulation strength.

Robust Corrosion Resistance: The oil tank shell utilizes a triple-layer anti-corrosion process (rust removal, phosphating, and multi-layer high-quality paint spraying) to effectively resist rust in hot and humid climates and extend the equipment's lifespan.

Fully Sealed Structure: Utilizing reliable sealing technology, this structure prevents air and moisture ingress, keeps the oil out of contact with the atmosphere, and slows aging, resulting in a truly maintenance-free, long-term operation.

Comprehensive Safety Protection: Standard features include a pressure relief valve, gas relay, and temperature control system, providing multiple protections against overload, overheating, and internal faults, ensuring safe and worry-free operation of the power station.

IV. Strict Quality Control and Smooth Delivery

We always consider product quality the cornerstone of our business. From raw material procurement to production and assembly, every step strictly adheres to the ISO9001 quality management system. Prior to shipment, this transformer passed a comprehensive suite of rigorous tests, including turns ratio testing, DC resistance testing, insulation resistance testing, power frequency withstand voltage testing, induction withstand voltage testing, and no-load and load loss testing. The product's superior quality earned the trust of our customers, successfully passing acceptance inspection, and was shipped on time to Cambodia on September 6th.
