China Reliable Power Transformer Manufacturer and Supplier
Power transformers are a crucial part of Ceho manufacturer's comprehensive product portfolio, providing reliable protection and efficient transmission for power systems. We employ advanced design techniques in manufacturing these products, offering both oil-immersed and dry-type transformers.
Dry-type transformers vs. oil-immersed transformers: Which to choose?
Ceho will provide advice based on your specific needs. If you intend to use it indoors, especially in environments where fire safety is paramount, such as high-traffic shopping malls, high-rise residential buildings, or schools, we recommend dry-type transformers. They use air or resin as the insulation/cooling medium, eliminating the risk of oil leakage and simplifying maintenance.
However, if you are using it outdoors or in industrial substations, oil-immersed transformers offer better heat dissipation and overload capacity, making them more economical and efficient for high-rated power applications.
Routine Maintenance
We provide comprehensive after-sales service and technical support, and also offer some product maintenance suggestions. Ceho products are relatively easy to install and maintain, requiring minimal checks or component replacements; regular inspections from necessary angles are sufficient.
The most basic and simplest method is visual inspection. Oil leaks, corrosion, the color of the silicone in the breather, and the integrity of bushings and gaskets are often detectable visually. If these issues arise during daily operation, they can be addressed immediately. Afterwards, electrical testing can be performed. For any questions or regarding how to develop a maintenance plan under operating conditions, please contact Ceho.
If possible, we recommend performing thermal imaging inspection, using an infrared thermal imager to identify hot spots on the bushings, joints, and tank surface. If you purchased one of our oil-immersed transformers, dielectric strength, moisture content, and dissolved gas analysis are also necessary to rule out internal faults through oil analysis.

Dry Type Amorphous Alloy Distribution Transformer
Ceho, a supplier of Dry Type Amorphous Alloy Distribution Transformer, can offer comprehensive product types for you choose, together with reliable technical support. An amorphous alloy dry-type transformer is a new type of low-loss dry-type transformer. Its most significant feature is low no-load loss and obvious energy-saving effect. It can save a lot of power plant investment and reduce the consumption of power generation fuel, thereby reducing the impact on the atmospheric pollution environment.
Epoxy Resin Cast Dry Type Distribution Transformer
Welcome to purchase this Epoxy Resin Cast Dry Type Distribution Transformer from Ceho factory. As the coils of the resin-insulated dry-type transformer are encapsulated by the epoxy resin, they are nonflammable, fireproof, explosion-proof, maintenance-free, no pollution, small volume, and can be installed in the load center directly. Meanwhile, the scientific and reasonable design and casting technology enable the products to have lower discharge capacity, low noise and strong heat dissipation. This product are able to run for a long time under 140% rated load under forced air cooling condition. Besides, the dry type transformer are equipped with intelligent temperature controllers, have functions of trouble alarm, over temperature alarm, over-temperature tripping and black box, can be connected with the computer through RS485 serial interface to realize centralized monitoring and control.

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.
As a reliable Power Transformer manufacturer and supplier in China, we have our factory. If you want to buy quality and durable products, please contact us.
