500KVA 10KV Pure Aluminum Oil Immersed Transformer: Economical Outdoor Power Distribution Core Equipment

 

Currently, the Power Distribution Equipment industry commonly suffers from the pain points of mixed materials and high procurement costs; purchasers often face challenges such as excessive equipment weight and poor compatibility with supporting equipment. We introduce the 500KVA 10KV Pure aluminum Oil Immersed Transformer, featuring an optimized all-aluminum winding structure. It can be flexibly paired with High And Low Voltage Switchgear and Box Type Substations to complete power distribution system construction, significantly reducing overall project investment compared to Dry Type Transformers of the same specifications. The equipment utilizes an oil-circulating heat dissipation structure to stably regulate voltage fluctuations, making it suitable for urban and rural power grids, small factories, and distributed photovoltaic projects. It can be used in conjunction with Electric Power Converters and Combined Photovoltaic Substations, with controllable long-term operating losses, significantly reducing subsequent maintenance costs.

 

This transformer’s rated parameters are suitable for 10kV municipal and industrial power distribution scenarios. Its pure aluminum windings undergo anti-oxidation curing treatment, resulting in lighter weight and lower transportation and hoisting costs. Outdoor installation requires no complex fireproof enclosures, making it suitable for temporary power supply at construction sites, rural power grid upgrades, and voltage boosting in small and medium-sized photovoltaic power plants. In complete power systems, it can serve as the core transformer unit within Combined Photovoltaic Substations, working in conjunction with a front-end Electric Power Converter to stabilize the photovoltaic side output current. If the project has indoor fire protection requirements, it can be simultaneously paired with a Dry Type Transformer for zoned power supply, with external High and Low Voltage Switchgear on the high and low voltage sides for segmented protection. The entire system is integrated within a Box Type Substation, shortening the on-site construction cycle. The equipment operates in compliance with noise control regulations, and its insulating oil sealing process prevents leakage. It is suitable for high-temperature and dusty outdoor conditions, maintaining stable power distribution efficiency over long-term use, balancing project budget with long-term power supply reliability.

 

Product Features

Lightweight design with pure aluminum windings: Compared to copper-core models, this reduces equipment weight, significantly lowering transportation and foundation construction costs, making it suitable for bulk outdoor power distribution projects.

Low-loss oil-cooled structure: Standard Oil-immersed Transformer cooling system ensures stable temperature rise under load fluctuations, suitable for continuous power supply scenarios in industrial and commercial applications.

 

Usage Tips

1.Before putting the equipment into operation, thoroughly check the oil level, sealing welds, and terminals to avoid long-term operation with leaks.

2.When installing with a box-type substation, ensure adequate ventilation and maintenance space, and periodically sample and test the insulating oil performance.

 

FAQ (Frequently Asked Questions)

Q1: Can this pure aluminum oil-immersed transformer be used in photovoltaic power plants?

A1: Fully compatible. It can be used as the core transformer in Combined Photovoltaic Substations, matching the front-end Electric Power Converter to complete photovoltaic voltage conversion. It is widely used in outdoor centralized grid-connected photovoltaic projects.

 

Q2: Is there a significant difference in service life between the pure aluminum winding equipment and the copper-core model? 

A2: After anti-corrosion and insulation treatment, its service life can reach twenty years under normal maintenance conditions. Its performance in stable load scenarios is almost identical to copper-core models, resulting in a significant overall cost advantage.

 

Q3: What basic checks are required for routine maintenance?

A3: Regularly check oil levels, for oil leaks, abnormal operating noises, and temperature readings; send the insulating oil for testing every 1-2 years. The testing cycle can be shortened in harsh environments.

 

Q4: What is the after-sales warranty period and fault response arrangement?

A4: The standard warranty for the entire unit is two years. The core winding enjoys long-term technical maintenance. Remote technical guidance is provided within 24 hours of receiving fault feedback. For large projects, engineers can be arranged for on-site commissioning and repair.

 

Q5: Compared to Dry Type Transformers, what scenarios is this product suitable for?

A5: It is primarily used in outdoor, open-air power distribution projects with limited budgets and stable loads. For indoor, enclosed scenarios with high fire protection requirements, it is recommended to use it in conjunction with Dry Type Transformers for zoned deployment.
