Low-Loss 35KV 1000KVA Oil-immersed Transformer for Stable Power Supply in Industrial Power Distribution

 

Currently, the power transmission and distribution industry commonly faces pain points such as high no-load losses, excessive energy consumption during long-term operation, and excessive temperature rise in aging transformers. Many factories and mines, after purchasing ordinary transformers, face persistently high electricity costs and frequent equipment maintenance as core concerns. To address these issues, our factory has launched a 1000KVA 35KV Low-Loss Oil Immersed Transformer. Paired with compatible High And Low Voltage Switchgear and Box Type Substations, it completes the power distribution system. It can also be used with Electric Power Converters and Combined Photovoltaic Substations to achieve grid-connected photovoltaic power supply. Compared to traditional Dry Type Transformers, it is more suitable for outdoor, high-capacity, long-term operation scenarios. The product utilizes a high-permeability silicon steel core with optimized winding structure, reducing no-load and load losses from the source. After being deployed in power grid upgrade projects in factories, mines, and rural areas, annual power loss can be significantly reduced, operating heat generation is lower, and the stable operating cycle of the equipment is greatly extended, balancing long-term operating costs and power supply safety. This equipment has a rated capacity of 1000KVA and a high-voltage side of 35KV, making it a core piece of medium- and high-voltage Power Distribution Equipment. It is widely used in self-provided power stations in industrial parks, open-pit mine power supply systems, urban and rural power grid upgrades, and photovoltaic Energy Storage supporting sites. It can be used independently as a main transformer or embedded in a complete distribution cabinet, flexibly combined with various power conversion and photovoltaic integration equipment, adapting to the needs of large-capacity power voltage regulation and transmission in multiple scenarios.

 

Product Features

Ultra-low loss operation design: The core iron core is processed using high-quality low-loss silicon steel sheets. Compared with conventional oil-impaired transformers, the no-load loss is significantly reduced, effectively reducing power resource waste during long-term continuous operation, and adapting to 24-hour uninterrupted power supply conditions.

 

Practical Tips

Installation and Matching Recommendations: When installing the equipment, simultaneously match it with a corresponding High and Low Voltage Switchgear. If used in a photovoltaic project, it can be directly connected to Combined Photovoltaic Substations to simplify the wiring process and reduce on-site modification work.

 

FAQ (Frequently Asked Questions)

Q: Can this 1000KVA 35KV Oil Immersed Transformer be used in a photovoltaic power station?

A: Yes. The equipment’s voltage regulation range is adapted to photovoltaic output conditions. Paired with an Electric Power Converter to regulate current and voltage, it can stably complete photovoltaic power boosting and transmission when connected to Combined Photovoltaic Substations.

 

Q: How long is the daily maintenance cycle, and is the operation difficult?

A: Under normal operating conditions, the insulating oil index should be checked every six months, and the winding and sealing structure should be fully inspected annually. The maintenance process is standardized, requiring no complex professional equipment; maintenance personnel can operate it after simple training.

 

Q: Compared with a Dry Type Transformer, how should one choose for outdoor projects? 

A: For outdoor, high-capacity, long-term power supply, the Oil Immersed Transformer is the preferred choice due to its superior heat dissipation efficiency; for indoor, enclosed spaces and scenarios with high fire safety requirements, the Dry Type Transformer is recommended.

 

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

A: The entire unit comes with a multi-year warranty and a factory inspection report. In case of non-human-caused malfunctions, the manufacturer provides remote technical guidance. For large projects, engineers can be dispatched for on-site repairs. Support is also provided for the repair of complete sets of equipment, including Box Type Substations and switchgear.
