Professional Manufacturer of CRGO transformer iron core

Electrical steel laminations, commonly referred to as EI laminations, find extensive application in diverse electrical and electronic fields. These laminations are manufactured using thin layers of electrical steel, enriched with silicon for superior magnetic characteristics. 

EI core laminations, composed of pure steel with a silicon content ranging from 0.5% to 5.5%, are widely employed in electrical and electronic equipment as low-frequency transformer cores. They enhance the magnetic properties essential for the functioning of transformers and motors. By transferring energy from the primary winding to the secondary winding, they aid in effective energy discharge. Different grades of laminations are available, categorized based on their silicon content, allowing for suitable selection according to the specific characteristics and requirements of the equipment and devices in use.

Transformer core is a crucial component that efficiently directs and transfers magnetic energy in electrical systems.

Fe-based nanocrystalline alloy strip has the properties of high saturation magnetization and permeability, low coercive force and core loss, good stabilities on temperature.

Our company specializes in producing oil-immersed and dry-type main transformers, covering capacities from 50kVA to 30000kVA. Utilizing our proprietary core lamination and coil winding processes, coupled with rigorous testing throughout the entire process, our products boast advantages such as low loss, low noise, short-circuit resistance, long lifespan, and stable operation. They meet international standards and can satisfy reliable power supply needs under various operating conditions and environments both domestically and internationally.

The S9 series three-phase oil-immersed distribution transformer is designed and manufactured according to national standards. It utilizes high-quality silicon steel sheets, oxygen-free copper windings, and a fully sealed oil-immersed structure, offering low loss, energy efficiency, reliability, and maintenance-free operation. It is suitable for various scenarios, including indoor and outdoor applications, and prefabricated substations.   The product boasts advantages such as efficient heat dissipation, short-circuit resistance, and strong overload capacity. It operates stably with low noise and is easy to install. It is widely used in urban and rural power grids, industrial plants, commercial buildings, and infrastructure distribution systems, making it a mainstream power distribution equipment with excellent cost performance.   Key parameters: Capacity 10kVA–6300kVA, high voltage 6/10/35kV, low voltage 0.4kV, oil-immersed self-cooling, fully sealed protection, suitable for environments from -25℃ to +40℃, and has passed all factory testing, ensuring quality.

The S11 series oil-immersed distribution transformer is a new generation of energy-saving power distribution equipment. It is designed and manufactured strictly in accordance with GB 1094 "Power Transformers", GB/T 6451 "Technical Parameters and Requirements for Three-Phase Oil-Immersed Power Transformers", and national energy efficiency standards. Compared to the S9 series, it reduces no-load loss by more than 30%, offering superior energy-saving performance and operational stability. It is suitable for urban and rural power grids, industrial plants, commercial buildings, residential communities, mines, and prefabricated substations, making it the preferred equipment for power grid upgrades, energy conservation, and safe power supply.

Dry-type transformers are power conversion equipment where the iron core and windings are not immersed in insulating oil, using air or solid insulating materials (epoxy resin, Nomex® , etc.) as the main insulating medium. They are core power distribution equipment for scenarios with high requirements for safety, environmental protection and reliability, such as high-rise buildings, hospitals, data centers, industrial parks and new energy supporting facilities. Relying on advanced technologies such as epoxy resin vacuum casting and amorphous alloy iron core, the products fully meet the requirements of GB 20052-2024 "Minimum Allowable Values of Energy Efficiency and Energy Efficiency Grades for Power Transformers", covering the full spectrum of Level 1 (NX1), Level 2 (NX2) and Level 3 energy efficiency. With the characteristics of low loss, low noise, maintenance-free and long service life, they provide all-dimensional support for the safe and stable operation of the power system.
