High-Efficiency 315KVA 20KV Oil-immersed Transformer for Stable Power Supply Solutions

 

Currently, the power distribution industry commonly suffers from the pain points of high losses in traditional transformer equipment and persistently high energy costs during long-term operation. Many purchasers are plagued by excessive temperature rise of aging equipment, high maintenance frequency, and poor compatibility with supporting equipment. We introduce the 315KVA 20KV High Efficiency Oil-immersed Transformer, which utilizes optimized core winding technology to create low-loss power supply equipment. It is compatible with various power supply devices, and long-term use can significantly reduce electricity costs and extend the service life of the entire unit.

 

This Oil Immersed Transformer has a rated capacity of 315KVA and a high voltage level of 20KV. Its core advantage lies in its upgraded Energy Efficiency. It is widely used in urban substations, industrial parks, and power supply scenarios in industrial and mining areas. It can also be used with Box Type Substations and High And Low Voltage Switchgear to build complete power distribution systems. To meet the needs of photovoltaic project construction, this equipment can be used in conjunction with Combined Photovoltaic Substations and Electric Power Converters to complete power conversion and scheduling. Compared with dry-type transformers of the same specifications, it offers superior heat dissipation performance under long-term outdoor operation, resulting in lower overall costs for both initial procurement and subsequent maintenance. The equipment utilizes high-permeability cold-rolled silicon steel sheets internally, significantly reducing no-load and load losses. Operating noise is kept within standard limits, and stable output is maintained even under harsh temperature and humidity conditions. It is suitable for diverse scenarios such as urban and rural power grid upgrades, power supply for new factories, and distributed photovoltaic systems. Whether for fixed distribution base stations or temporary industrial power supply projects, it ensures stable power transmission, reduces equipment losses caused by voltage fluctuations, helps enterprises reduce long-term power operating expenses, and improves the overall operating efficiency of the power distribution system.

 

Product Features 

Ultra-High Energy Efficiency Loss Control: As a High Efficiency Oil-immersed transformer, the optimized core winding design results in no-load losses far below industry standards, enabling sustainable power savings during long-term continuous operation and making it suitable for long-term uninterrupted power supply conditions.

Multi-device compatibility: Seamlessly integrates with a full range of power components including Box Type Substations, Combined Photovoltaic Substations, and Electric Power Converters, without requiring additional modifications to the overall power distribution architecture.

 

Practical Tips

1.Sufficient ventilation and heat dissipation space should be reserved during equipment installation. 2.Regularly check the insulating oil level to prevent accelerated oil aging in high-temperature environments and extend the overall lifespan of the unit.

 

FAQ

Q: Is this 315KVA 20KV Oil Immersed Transformer suitable for outdoor photovoltaic power stations?

A: Absolutely. The equipment's protective structure is adapted to outdoor environments and can be directly paired with Combined Photovoltaic Substations and Electric Power Converters to complete photovoltaic power transformation and transmission. Its heat dissipation performance is superior to that of a Dry Type Transformer of the same capacity.

 

Q: What routine maintenance is required? How often should maintenance be performed?

A: Check the insulating oil quality and terminal tightness every six months, and conduct a comprehensive winding insulation performance test annually. Compared to dry-type equipment, the oil-immersed model only requires periodic oil replenishment, resulting in fewer maintenance procedures.

 

Q: What does the after-sales warranty cover? How are malfunctions handled?

A: The entire unit comes with a standard warranty, including free repair and replacement of the core iron core and windings for non-human-caused damage. Technical support personnel are available in various locations to provide rapid remote guidance or on-site repair after fault feedback, along with corresponding high and low voltage switchgear maintenance solutions.

 

Q: Can you supply complete sets of box-type substations and high and low voltage switchgear?

A: Complete customization is supported. Box-type substations, high and low voltage switchgear, and corresponding electric power converters can be provided simultaneously, offering a one-stop solution for complete photovoltaic and industrial power distribution facilities.
