A Силовой трансформатор 35 кВ is commonly used to transform electrical energy between a 35kV network and lower distribution voltage levels. Compared with higher-voltage transmission transformers, 35kV transformers are widely used closer to industrial facilities, renewable energy projects and regional distribution networks.
The transformer must provide stable voltage conversion while maintaining low losses, reliable insulation performance and sufficient short-circuit withstand capability.
Liye designs each 35kV transformer according to the actual electrical system rather than relying only on a fixed standard configuration.
● Reliable insulation structure for medium-voltage operation
● Optimized core and winding design
● Low no-load and load losses
● Low-noise operation
● Strong short-circuit resistance
● Stable temperature-rise performance
● Reliable oil circulation and cooling design
● Custom electrical parameters for different projects
For utility and industrial applications requiring reliable continuous operation, the 35kV oil immersed transformer uses transformer oil as both an insulating and cooling medium.
The oil-immersed structure supports effective heat dissipation and is suitable for medium- and large-capacity power distribution applications.
Depending on project requirements, Liye can evaluate:
● Transformer rated capacity
● Primary and secondary voltage
● Two-winding or three-winding design
● Tap-changing requirements
● Vector group
● Short-circuit impedance
● Insulation level
● ONAN or other required cooling configurations
● Loss and efficiency requirements
● Temperature-rise limits
● Noise requirements
● Monitoring and protection accessories
● Indoor or outdoor installation conditions
This engineering flexibility allows the 35kV oil immersed transformer to be matched to different substation layouts and electrical systems.
Liye 35kV power transformers can be applied in a wide range of medium-voltage distribution and industrial power projects.
A 35kV substation transformer can step incoming medium-voltage power down to the voltage required by factory distribution systems and production equipment.
Typical applications include:
● Steel and metallurgical plants
● Chemical facilities
● Manufacturing factories
● Mining projects
● Industrial parks
● Large infrastructure facilities
35kV networks are also widely used for power collection and distribution in renewable energy projects.
Liye can provide 35kV transformer solutions for:
● Solar power stations
● Wind farms
● Energy storage systems
● Hydrogen production projects
● Renewable energy substations
Transformer specifications can be adapted according to the project’s grid connection and electrical design.
A 35kV distribution transformer can also be used in regional substations and distribution networks where power must be transformed from a 35kV system to a lower voltage level before further distribution.
Most industrial and utility applications require a three phase 35kV transformer designed according to the site’s electrical parameters.
Liye supports customized transformer engineering based on customer specifications and project drawings.
When requesting a transformer, buyers can provide:

Liye has specific technical experience in the 35kV transformer class. In 2022, the company independently developed an energy-efficient 35kV natural ester insulating oil power transformer, demonstrating its R&D capability in both medium-voltage transformer engineering and environmentally oriented insulation technology.
Liye’s transformer production and R&D capabilities extend to transformers up to 750kV.
For buyers evaluating a 35kV transformer supplier, this broader engineering capability provides additional support in insulation design, winding manufacturing, transformer testing and project-specific customization.
Reliable factory testing is important before a Силовой трансформатор 35 кВ is shipped to the project site.
Liye operates a dedicated transformer testing center for electrical performance verification. Depending on transformer design, customer requirements and applicable standards, required factory tests can be arranged before delivery.
Testing and quality control help confirm transformer performance before installation and commissioning.
A Силовой трансформатор 35 кВ is a medium-voltage electrical transformer used to convert electrical energy between a 35kV power system and another voltage level. It is commonly used in substations, industrial facilities, renewable energy plants and regional distribution networks.
35kV transformers are widely used in industrial substations, factories, mining facilities, solar plants, wind farms, energy storage projects and utility distribution networks.
Yes. Liye can customize the transformer according to capacity, voltage ratio, winding configuration, impedance, tap range, vector group, insulation level, cooling method and operating environment.
In many product and procurement classifications, a 35kV transformer is categorized as a medium-voltage power transformer. Liye therefore positions its 35kV product range primarily for medium-voltage distribution and substation applications.
For an accurate quotation, provide the required capacity, primary and secondary voltage, frequency, vector group, impedance, tapping range, cooling method, applicable standard and installation environment.
