Engineers customize parameters according to customer needs, such as
-voltage level
-capacity
-protection level
Optimize electromagnetic field distribution through computer simulation to ensure efficient operation of the transformer.
In-sales Quality Control
Qianhong Electric always regard quality as the top priority of our enterprise, and over 20 years manufacturing experience have equipped us with comprehensive quality inspection system.
From design customization, coil winding, insulation treatment,Core manufacturing, final assembly and test center, every step undergoes rigorous testing repeatedly to ensure that every unit 100% meets the standards before being allowed to be shipped.

Comprehensive Customization Capabilities
Efficient Manufacturing & Flexible Production
Our power transformer production lines are equipped with advanced automation and precision testing systems, allowing for fast delivery and small-batch customized production. Customers can choose from various transformer types according to their project needs. Whether for standard applications or specialized industry requirements, we provide personalized solutions.
Comprehensive Custom Design Service
Qianhong possesses strong customization capabilities for power transformers, offering tailored designs based on specific customer requirements. This includes adjustments in capacity, output voltage, cooling methods, and physical dimensions, ensuring that the transformer operates efficiently and reliably in various working environments and meets complex load demands.
Coil Winding Control
Coil winding is the key process, we adopt copper or aluminum with high conductivity as the conductor, then precisely winding by automated equipment,errors controll in mm level,wrapped insulations between layers to prevent short circuits.The transformer insulation adopts F-grade DMD high temperature resistant insulating paper, which has good mechanical strength.
Core Manufacturing Control
Our core adopted with laminated silicon steel sheets of high magnetic permeability to reduces iron loss and eddy current loss,the silicon steel sheets undergo processes such as cutting, stacking, and fastening to ensure magnetic permeability and mechanical strength. The error is controlled in millimeters level to avoid noise and loss.
Quality Testing Control
Our test center run a comprehensive testing process strictly include voltage ratio and connection,winding resistance,insulation resistance,induced voltage withstand,no-load loss and current,load-loss and impedance voltage test,power frequency,sealing test and son on to ensure every unit undergoes each testing and meets standards before being allowed to be shipped.
