35kV On-Load Tap-Changing Transformers
1600 kVA 35 kV Oil-Immersed power Transformer
The industry's pain points mainly lie in the insufficient stability of high- Power Distribution Equipment , the difficulty in expansion, and the poor adaptability. Your problem is that it is difficult to find a power supply device that can adapt to high-load scenarios, balance cost performance and ease of operation. We have specially developed a 1600KVA/ 35kv Transformer , which can be flexibly combined with Dry Type Transformer or Oil Immersed Transformer , and is paired with High And Low Voltage Switchgear to achieve precise power distribution. In practical applications, it can stably carry a power load of around 1280kW, effectively solving the problem of unstable power supply in high-load scenarios, and reducing operation and maintenance costs. The core value of this product lies in achieving efficient conversion from 35KV high voltage to 0.4KV low voltage, adapting to heavy-load scenarios such as large-scale industries and new energy, and can operate in conjunction with Box Type Substation and Electric Power Converter , or connect to Combined Photovoltaic Substations for grid connection, ensuring efficient, safe and reliable power transmission.

Product overview
The industry's pain points mainly lie in the insufficient stability of high- Power Distribution Equipment , the difficulty in expansion, and the poor adaptability. Your problem is that it is difficult to find a power supply device that can adapt to high-load scenarios, balance cost performance and ease of operation. We have specially developed a 1600KVA/ 35kv Transformer , which can be flexibly combined with Dry Type Transformer or Oil Immersed Transformer , and is paired with High And Low Voltage Switchgear to achieve precise power distribution. In practical applications, it can stably carry a power load of around 1280kW, effectively solving the problem of unstable power supply in high-load scenarios, and reducing operation and maintenance costs. The core value of this product lies in achieving efficient conversion from 35KV high voltage to 0.4KV low voltage, adapting to heavy-load scenarios such as large-scale industries and new energy, and can operate in conjunction with Box Type Substation and Electric Power Converter , or connect to Combined Photovoltaic Substations for grid connection, ensuring efficient, safe and reliable power transmission.
1.High load adaptability is outstanding: Specifically designed for high-load scenarios, it can stably handle the power consumption of large motors, production lines and other heavy-load equipment. It can seamlessly connect with Combined Photovoltaic Substations and Electric Power Converters, meeting the requirements for grid connection of new energy and industrial heavy-load power distribution. When paired with Box Type Substation, it can achieve integrated power distribution.
2. Safe and Easy Maintenance: The Oil Immersed Transformer adopts an anti-corrosion and sealed design, suitable for outdoor harsh environments with excellent heat dissipation performance; The Dry Type Transformer has outstanding fire resistance and is suitable for indoor enclosed scenarios. Both are equipped with simple maintenance designs. When combined with High And Low Voltage Switchgear, they can quickly identify faults and reduce maintenance complexity.
1.The selection should take into account the peak load. If it is used in a new energy project, it is recommended to combine with Combined Photovoltaic Substations and Electric Power Converter to ensure grid connection stability; for outdoor heavy-load scenarios, Oil Immersed Transformer should be preferred, and for indoor precision scenarios, Dry Type Transformer should be selected.
2. Daily operation and maintenance mainly focus on monitoring the temperature rise of equipment. For oil-immersed transformers, regular inspections of the oil condition are necessary. For dry-type transformers, ensure proper ventilation and dryness around the unit to prevent the accumulation of debris that could hinder heat dissipation.
Design features
What the design is built around
Low-loss magnetic core
Cold-rolled grain-oriented silicon steel and a stepped core reduce no-load loss and audible noise.
Sealed tank construction
Welded tank, quality-gasketed cover and pressure-tested seals reduce oil leakage risk in outdoor duty.
Thermal margin for hot climates
Cooling surfaces and oil volume are selected for high ambient temperature and cyclic loading.
System compatibility
MV terminals, cable boxes and LV bushings are matched to the switchgear and protection scheme.
