35kV Oil-Immersed Power Transformer

Safe and Reliable: We use high-quality materials and advanced manufacturing processes to ensure that our equipment meets the highest standards of performance and quality. In addition, oil-immersed transformers boast strong overload capacity, effectively preventing equipment damage and safety incidents. High Efficiency and Energy Saving: These transformers feature high efficiency and low losses, significantly reducing energy waste and carbon emissions. They are equipped with an advanced cooling system that lowers operating temperatures, enhances heat dissipation efficiency, and minimizes energy loss. Long Service Life: The transformer employs a vacuum oil-injection process, which reduces moisture inside the core, improves internal insulation performance, slows down the aging of insulating oil, extends service life, and reduces partial discharge phenomena. Simple Maintenance: The transformer requires only periodic checks on oil levels, pressure, gas content, temperature, and other key parameters to ensure normal operation. Regular testing and cleaning to remove dust and oil buildup can further extend the equipment’s lifespan and enhance its performance and operational effectiveness.

Detailed description

The 35kV liquid-immersed power transformers represent our company’s mature and stable flagship product series, primarily including models such as S18, S20, and S22. These transformers fully meet the Level 3, Level 2, and Level 1 energy efficiency requirements specified in GB20052-2024 “Energy Efficiency Limit Values and Energy Efficiency Levels for Power Transformers,” making them suitable for a wide range of power application scenarios that place high demands on energy conservation and operational reliability.

In terms of capacity coverage, products rated at 35 kV and below can achieve a maximum capacity of up to 31,500 kVA, meeting the requirements of conventional grid construction as well as power supply for high-capacity loads.

The transformer core is made of high-quality cold-rolled grain-oriented silicon steel sheets, assembled using a multi-stage 45° fully skewed lap-joint structure, which effectively reduces no-load losses and noise levels, thereby enhancing overall operational efficiency.

The winding structure design is flexible and can be tailored to different capacity levels and application conditions by selecting either a cylindrical or disc-type coil configuration. This product boasts a highly versatile structural design that simultaneously meets stringent requirements for electrical performance, mechanical strength, and thermal stability. During manufacturing, a vacuum oil-immersion process is employed, significantly enhancing the impregnation quality of the internal insulation system and improving overall insulation performance. This process effectively slows down the aging rate of the insulating oil, reduces partial discharge levels, and extends the service life of the equipment.

This product series can be widely used in conventional power systems such as urban and rural grid upgrades and substation construction. It also meets the stringent requirements of industrial systems—including metallurgy and petrochemical industries—for high reliability, weather resistance, and operation under special outdoor conditions, demonstrating excellent environmental adaptability and long-term operational stability.

Dry-Transform Energy Storage Integrated Unit—Container Structure

Dry-Transform Energy Storage Integrated Unit—Container Structure

Safe and Reliable: The packaged substations are equipped with comprehensive electrical protections against overload, short circuit, ground fault, and other electrical hazards. The transformers themselves feature non-electrical protections such as temperature, oil level, pressure, and gas monitoring. Moreover, the system can be monitored in real time from the background control center, and remote operations can be performed from there, ensuring the continuous safe operation of the equipment at all times. High Integration: The entire system is pre-manufactured and pre-commissioned at the factory. After integration and testing, it is delivered to the site as a complete unit. On-site, all that’s required is connecting the high- and low-voltage cables and control/communication cables to put the system into operation—thus significantly reducing on-site work and boosting construction efficiency. Energy-Efficient and Environmentally Friendly: The transformers are made from energy-saving and environmentally friendly materials, and their design has been optimized to minimize no-load losses and improve operational efficiency, meeting national energy-saving standards. An advanced cooling system is employed to lower operating temperatures, enhance heat dissipation efficiency, and reduce energy losses. Flexible Configuration: Whether it’s a photovoltaic power generation or wind power generation project, we can provide tailored packaged substation solutions. Based on the specific site conditions and project requirements, we’ll rationally configure the substation’s capacity, incoming and outgoing cable connections, protection levels, and other parameters to meet the unique needs of each site.
