Recently, our company successfully completed an order for an oil-immersed transformer exported to Sri Lanka.
1. Capacity: 10kVA
2. High Voltage: 33kV
3. Low Voltage: 0.064kV
4. Cooling Method: ONAN Oil-Immersed Self-Cooling
5. Standard: IEC Standard
From technical confirmation, manufacturing, quality inspection to final delivery, our company provided our customer with professional services throughout the entire process. The online testing and shielded partial discharge laboratory demonstration received high praise from the customer.
Considering international travel costs and project timelines, the Sri Lankan customer chose to complete the factory acceptance via online video.
Our company arranged a professional testing team to conduct real-time online testing via Zoom video conferencing.
1. Overall product appearance
2. Nameplate and technical parameters
3. Manufacturing process details
4. Full factory testing process
5. Real-time test data
During testing, our engineers complete the following on-site tests:
1. Turnover ratio test
2. DC resistance test
3. Insulation resistance test
4. Polarity test
5. No-load loss test
Power frequency withstand voltage test
All data is displayed in real time. Customer technical teams can ask questions and confirm online, achieving the same effect as on-site inspection.
In addition to routine factory testing, we also highlighted our Partial Discharge Shielded Laboratory to our customers.
This laboratory employs a professional electromagnetic shielding design, effectively isolating external electromagnetic interference and providing a stable and accurate testing environment for high-voltage products.
The laboratory can perform:
1. Partial Discharge Test
2. Power frequency withstand voltage test
3. Induced withstand voltage test
4. High-voltage insulation performance testing
5. Product type testing support
Through testing in the shielded partial discharge laboratory, potential defects in the insulation system can be effectively detected, ensuring the long-term safe and stable operation of the product.
For products with voltage levels of 33kV distribution transformer and above, partial discharge control capability is a crucial indicator of manufacturing quality and a key testing focus for many overseas customers.
During this online inspection, the customer not only witnessed the product's routine factory testing but also toured our shielded partial discharge laboratory via live video.
Our engineers provided a detailed introduction to:
1. Laboratory layout
2. Partial discharge testing system
3. High-voltage testing equipment
4. Quality control processes
Implementation of testing standards. The customer gained a clear understanding of our testing capabilities and quality management system through the remote video, highly praising the company's technical strength.
Focusing on the manufacturing of oil immersed transformer, distribution transformers, and power equipment.
Customers can remotely participate in product acceptance and testing witnessing regardless of their location.
Possessing the capability for partial discharge testing and insulation performance verification of high-voltage products.
Products are designed, manufactured, and tested according to international standards such as IEC.
Providing technical support, inspection services, export documentation, and after-sales support.
After completing the online inspection, the Sri Lankan customer expressed full satisfaction with the product quality, testing process, and the professional capabilities of our shielded partial discharge laboratory, and successfully completed the acceptance confirmation.
"Through the online testing and laboratory demonstration, we not only saw the actual testing process of the product but also witnessed the factory's strong testing capabilities, which gave us greater confidence in the product quality."
Our company always adheres to a quality-centric approach and is customer-demand-oriented. Through our online testing service and shielded partial discharge laboratory testing platform, we provide global customers with a more transparent, efficient, and reliable inspection experience, allowing customers even those overseas to purchase and use products with peace of mind.
