35KV 2000KVA All-Copper Oil-immersed Transformer: Stable Power Supply for Multiple Power Engineering Scenarios

 

Currently, the high-voltage power distribution field suffers from common industry pain points such as high equipment losses and shortened service life due to aluminum incorporation in winding materials. Many project purchasers face the challenge of severe heat generation during equipment operation and persistently high long-term maintenance costs. To address these issues, we have launched the 2000KVA 35KV Pure copper Oil-immersed Transformer. Its core structure with pure copper windings optimizes overall performance, and its mature heat dissipation oil circuit design effectively reduces power loss and significantly lowers the long-term failure rate when used in power plants and industrial areas. This equipment is suitable for multiple scenarios including large-scale factory power supply, urban substation upgrades, and photovoltaic power transmission. It can be combined with Dry Type Transformers and Box Type Substations to build complete power distribution systems. It can also be used with High And Low Voltage Switchgear for high and low voltage line regulation and with Electric Power Converter to adjust power output parameters. It is an indispensable core power equipment for building Combined Photovoltaic Substations. The entire unit utilizes high-purity copper for its internal windings, offering significantly superior conductivity compared to aluminum products. It ensures stable voltage output even under fluctuating load conditions. The large-capacity 2000KVA configuration can meet the continuous power supply needs of large industrial clusters and centralized photovoltaic power plants. Its sealed oil-immersed structure isolates it from moisture and dust, allowing for long-term stable operation even when installed outdoors, greatly reducing downtime for maintenance and compressing overall operating costs for power projects. The equipment undergoes rigorous testing for withstand voltage, load, and temperature rise before leaving the factory. It comes with complete installation drawings and a maintenance manual, conforming to most domestic and international high-voltage power distribution construction standards. It can be used independently as a main transformer or integrated into complete substation systems, adapting to diverse power project needs.

 

Product Features

Pure Copper Winding Low-Loss Design: The entire unit uses pure copper windings, which, compared to ordinary aluminum core oil-immersed transformers, reduces no-load losses and allows for controllable temperature rise during long-term high-power operation, making it suitable for 24-hour uninterrupted industrial power supply scenarios.

Fully Sealed Oil Circuit Protection Structure: The sealed oil tank isolates the equipment from external moisture and corrosive gases. Outdoor installation with a Box Type Substation eliminates the need for additional complex moisture-proof accessories, simplifying on-site construction.

 

Maintenance Tips

Regular Oil Level and Temperature Inspection: Check the equipment's insulating oil level quarterly. Under high-temperature conditions, use a High And Low Voltage Switchgear to simultaneously monitor the line load, preventing overload damage to the windings.

Moisture-Proof Storage for Idle Equipment: For long-term shutdowns, seal the terminals and store the equipment separately from the Dry Type Transformer to prevent moisture corrosion of the insulation components.

 

FAQ (Frequently Asked Questions)

Q: Can this 2000KVA 35KV Pure copper Oil-immersed Transformer be used in Combined Photovoltaic Substations?

A: Fully compatible. The equipment's voltage conversion range matches the photovoltaic power station transmission standards. When paired with an Electric Power Converter, it can stably regulate the photovoltaic output power, making it suitable for centralized photovoltaic substation projects.

 

Q: Is the daily maintenance of oil-immersed equipment more difficult than that of a Dry Type Transformer?

A: Basic maintenance is simple, requiring only periodic testing of the insulating oil quality. Dry-type equipment does not require oil changes, but under high-capacity continuous load conditions, the oil-immersed transformer offers superior heat dissipation.

 

Q: What is the after-sales warranty period for the equipment, and how are malfunctions handled?

A: The entire unit comes with a standard warranty service and a complete spare parts list. Remote technical guidance is available for operational malfunctions. For large projects, engineers can be arranged for on-site repairs, and a high and low voltage switchgear repair plan is also provided.

 

Q: Does it support complete sets shipped with Box Type Substations?

A: Complete customization is supported. High and low voltage cabinets, main transformers, and conversion devices can be supplied as a single unit, shortening the on-site assembly period.
