Project Background
In Canada, the energy demand in industrial and commercial sectors is rapidly increasing due to urban growth, technological advancements, and a shift toward renewable energy sources. To meet this demand, electrical infrastructure must not only provide reliable and efficient power but also adapt to extreme weather conditions, especially in northern and remote areas. A leading Canadian industrial facility, involved in high-demand manufacturing, required a transformer capable of handling large loads while operating efficiently in a cold and variable climate. The facility opted for a 10 MVA Vacuum Pressure Impregnation (VPI) H-Class Dry-Type Transformer to ensure continuous, reliable, and safe power delivery.
Performance Results
- Reliable Power Supply: Since installation, the transformer has provided a consistent and reliable power supply to the manufacturing facility, with no unplanned downtime or power interruptions. The transformer effectively supports the power needs of heavy machinery and industrial equipment, ensuring smooth operations.
- Cold Weather Performance: The transformer has performed flawlessly during Canada’s harsh winters, maintaining stable performance even in sub-zero temperatures. The VPI insulation and H-Class materials have proven resilient, protecting the transformer’s internal components from environmental stress.
- Energy Efficiency: The facility has reported a noticeable reduction in energy consumption compared to previous transformer models, thanks to the high efficiency of the VPI H-Class Dry-Type Transformer. This has led to cost savings in electricity bills over the long term.
- Safety and Low Maintenance: As a dry-type transformer, the risk of fire or oil leakage has been eliminated, improving safety standards in the facility. The transformer also requires minimal maintenance, as the VPI technology and H-Class insulation provide superior longevity and protection against wear and tear. The low maintenance requirement has reduced downtime and operational costs.
Product Introduction
We delivered 5 units of 10 MVA VPI dry type transformers to Canada in 2020, the rated power of the transformer is 10000 KVA. the primary voltage of the transformer is 24.94 KV and secondary voltage is 4.16 KV. We designed 115℃ temperature rise and H class insulation which can suffer 220℃ max temperature, the dry type transformers are equipped with winding temperature indicator, pad absorbers, grounding connectors, seismic absorbers, heating system, fan and controller, lighting arresters, CTs, enclosure. Our 10 MVA Dry Type Transformer was designed with advanced technology and adopts high quality material and components which result in reliable quality and long operation time.
We ensure that each one of our delivered units has undergone rigorous full acceptance testing. We provide one-package service from consulting, quoting, manufacturing, installation, commissioning, training to after sale services, our products are now operating in more than 50 counties in the world. We aim to be your most reliable supplier as well as your best partner in business!
