Product overview
High-Efficiency 2000KVA 20KV Oil-immersed Transformer : Stable Power Supply for Industrial Power Systems
Currently, the power infrastructure industry commonly faces pain points such as high losses in Power Distribution Equipment and persistently high energy costs during long-term operation. Many industrial and mining projects, as well as photovoltaic projects, often encounter problems such as severe equipment overheating, frequent maintenance, and insufficient power supply stability. To address these issues, our factory has launched the 2000KVA 20KV High Efficiency Oil Immersed Transformer . Utilizing optimized core winding technology to reduce no-load and load losses, it is suitable for diverse scenarios such as factory power distribution, photovoltaic power station support, and urban power grid upgrades. It can be used in conjunction with Box Type Substations and High And Low Voltage Switchgear , or combined with Electric Power Converters and Combined Photovoltaic Substations to build a complete power supply system. Compared to conventional oil-immersed equipment, long-term use can significantly reduce electricity costs, control power fluctuations within a standard range, and is suitable for long-term continuous outdoor operation. Compared to dry-type transformers of the same specifications, it has stronger overload tolerance and lower manufacturing costs. This equipment is primarily used in large factories, mining areas, distributed photovoltaic parks, and municipal substations, undertaking high-voltage power conversion and voltage stabilization transmission. It balances economic efficiency with operational safety and is compatible with domestic and international 20KV standard power grid conditions.
Design features
What the design is built around
Ultra-low loss, high-efficiency core
Utilizing a new lamination process to create the core structure, a core advantage of the High Efficiency Oil Immersed Transformer, it ensures controllable temperature rise during long-term full-load operation, adapting to the uninterrupted power supply requirements of Combined Photovoltaic Substations and significantly reducing long-term power consumption.
Strong compatibility and adaptability
Seamlessly connects to Box Type Substations and High and Low Voltage Switchgears. It can also work with Electric Power Converters to complete photovoltaic power voltage regulation and conversion, facilitating one-stop construction of a complete power distribution system for customers.
Practical Tips
Ensure adequate ventilation and heat dissipation space during equipment installation. Regularly check the insulating oil condition and avoid prolonged direct contact with dust and corrosive gases to extend the overall service life of the unit.
