Customized Oil Immersed Transformer Manufacturer in China
Oil immersed transformers, Ceho factory's high-quality products, enable efficient transmission over long distances, and are more durable in high-capacity, continuous operation applications through insulating oil as cooling and medium.
Operating Principle
This kind of product is different from dry-type transformer, we will introduce its core principle for you, which has nothing to do with its structure.The core is laminated from high-quality oriented silicon steel sheets to provide a low-reluctance path for magnetic flux. Around the core, primary and secondary windings insulated with high-quality paper or polymer material are wound to form the active components and enclosed in a sealed, robust steel tank.Work by filling the tank with transformer oil.
What Standard Tests Are Performed Before New Transformers Are Delivered?
Ceho certainly understands the quality concerns and every new oil-immersed transformer is tested in our factory first, including routine and type tests.
Specific items include winding resistance measurement, voltage ratio and vector group verification, no-load and load loss measurement, impedance voltage measurement, dielectric test, high voltage winding lightning impulse test, temperature rise test and oil pressure tightness test.

Amorphous Alloy Distribution Transformer
As a professional high-quality Amorphous Alloy Distribution Transformer manufacturer, Ceho wishes to establish long-term cooperation with you. This product is applicable to the power system and serves as the main transformer equipment in small and medium-sized substations, providing power distribution and power lighting for industry and agriculture. The company has introduced advanced technologies both at home and abroad, adopted the latest materials, and optimized the design, making the product structure more reasonable and significantly enhancing the electrical strength, mechanical strength and heat dissipation capacity of the products.
Dual Winding Oil Immersed Distribution Transformer with On-Load Tap Changer
As a reliable manufacturer in China, Ceho provides high quality and advanced Dual Winding Oil Immersed Distribution Transformer with On-Load Tap Changer. The product is a powerful and universal medium-voltage distribution solution that can provide real-time voltage regulation without interrupting the power supply.
Three-Phase Oil Immersed Distribution Transformer with On-Load Tap Changer
Three-Phase Oil Immersed Distribution Transformer with On-Load Tap Changer are important equipment in modern distribution systems, also one of Ceho's important products. These products can regulate voltage without interrupting the load, improving power quality and grid stability.
Oil Immersed Distribution Power Transformer
China Oil Immersed Distribution Power Transformer manufacturer Ceho can offer one-stop solutions! The S20-M-30-2500/10-NX2 series fully sealed oil-immersed power transformers professionally developed and produced by Ceho feature low loss, low noise and high efficiency, which can achieve excellent energy-saving effects and reduce pollution. Compared with ordinary oil-immersed transformers, fully sealed oil-immersed transformers eliminate the oil storage tank. The change in oil volume is automatically regulated and compensated by the elasticity of the corrugated plates in the corrugated oil tank. The transformer oil is isolated from the air, preventing and slowing down the deterioration of the transformer oil and insulation aging, enhancing operational reliability, and requiring no maintenance during normal operation.
Three-Dimensional Wound Core Distribution Transformer
The Three-Dimensional Wound Core Distribution Transformer represents a new generation of highly reliable transformer products featuring a more rational structure, superior performance, and lower manufacturing costs. This product breaks away from traditional planar designs by adopting a two-phase symmetrical three-dimensional structure. Furthermore, the absence of air gaps in its magnetic circuit ensures the magnetic flux direction of the silicon steel strips perfectly aligns with the magnetic path. The three core columns are arranged in an equilateral triangular configuration, resulting in identical and minimized magnetic circuit lengths. This design enables precise nesting during manufacturing with zero material waste.
Fully Sealed Oil-Immersed Distribution Transformer
You can rest assured to buy Ceho Fully Sealed Oil-Immersed Distribution Transformer. Compared to the "9" type transformer, this transformer achieves an average reduction of approximately 30% in no-load losses. Compared to the JB/T10088-1999 standard, it operates at a lower noise level, reduced by approximately 7dB. The temperature rise of the oil surface and high/low voltage windings is approximately 20K-13K lower than the temperature rise limit, indicating a certain overload capacity. It possesses strong short-circuit resistance and high reliability.
Oil Immersed Distribution Transformer with No-Load Tap Changer
Oil Immersed Distribution Transformer with No-Load Tap Changer is offered by Ceho, a professional manufacturer with good after-sale service. This transformer is a type of transformer designed for medium-voltage power distribution networks. It uses mineral oil for insulation and cooling, and includes a tap changer that can only adjust voltage ratios when the transformer is de-energized—hence the term "no-load."
