Low-Loss 500KVA 20KV Oil-immersed Transformer Stable Power Distribution Solution

 

Currently, the power grid transformation and photovoltaic power plant support sectors commonly face the pain points of high no-load losses in Power Distribution Equipment and persistently high long-term energy costs. Most companies use ordinary power distribution equipment, resulting in continuous additional electricity expenses, and excessive equipment temperature rise can shorten the overall lifespan of the power supply system. We introduce the 500KVA 20KV Low Loss Oil Immersed Transformer, which reduces losses through optimized core winding structure, adapting to various power supply scenarios and providing stable power output. After the equipment is put into operation, annual energy consumption is significantly reduced. Combined with a box-type substation and a high-and-low voltage switchgear, a complete power distribution system can be built, catering to the diverse power needs of industrial plants, photovoltaic power plants, and municipal power grids.

 

This Oil Immersed Transformer has a rated capacity of 500KVA and a high-voltage side voltage level of 20KV. Its core advantage focuses on low-loss energy-saving design, significantly reducing no-load and load losses compared to conventional models. In Combined Photovoltaic Substations projects, it is often used in conjunction with an Electric Power Converter to achieve stable voltage regulation and transmission of photovoltaic power. It can also be flexibly combined with a Dry Type Transformer to customize power distribution layouts based on different indoor and outdoor installation environments. The product boasts excellent overall structural sealing, and its insulation materials exhibit outstanding aging resistance, making it less prone to leakage and overheating during long-term continuous operation. It can meet the continuous power supply needs of factories, and can also be used for rural power grid expansion and centralized power distribution in commercial complexes. Long-term use can significantly reduce maintenance and electricity costs for purchasers, aligning with medium- to long-term power infrastructure procurement plans.

 

Product Features

Low-loss core construction: Constructed with exclusive low-magnetic-density silicon steel sheets, resulting in a significant reduction in losses compared to ordinary oil-impregnated transformers, leading to outstanding energy-saving benefits over long-term operation.

Wide operating condition adaptability: Adaptable to 20KV high voltage in various photovoltaic and industrial scenarios, it can be integrated with various complete sets of power distribution equipment to achieve integrated power supply construction.

 

Usage Tips

Equipment installation requires sufficient space for ventilation and heat dissipation.When using the accompanying Box Type Substation, regularly check the cabinet ventilation openings to prevent dust accumulation and obstruction of heat dissipation.

 

FAQ

Q:Can this 500KVA 20KV Oil Immersed Transformer be used with photovoltaic (PV) equipment?

A:Yes, this equipment is compatible with Combined Photovoltaic Substations and can be used with an Electric Power Converter to perform PV voltage boosting and stabilization operations, suitable for small to medium-sized PV power plant construction.

 

Q:How ​​to differentiate between Oil Immersed Transformer and Dry Type Transformer?

A:For outdoor, large-capacity, long-term power distribution scenarios, the oil-immersed type is preferred. For indoor, enclosed locations with strict fire safety requirements, the Dry Type Transformer can be used. Both can be combined with a High And Low Voltage Switchgear for complete system installation.

 

Q:How ​​often is the equipment maintained, and is it difficult to operate?

A: Under normal operating conditions, oil level and sealing welds should be inspected every six months, and insulation testing should be performed annually. Maintenance procedures are standardized, requiring no complex professional tools; the complete inspection steps are outlined in the equipment manual.

 

Q:What services are included in the after-sales warranty?

A: The entire unit comes with a standard warranty period, during which non-human-caused parts will be replaced free of charge. Remote technical guidance is also provided, and on-site commissioning services are available for complete sets of equipment including Box Type Substations and switchgear.
