power transformer

 

YAWEI has developed highly reliable power transformers that serve as the core equipment in power transmission and distribution networks. Through extensive R&D in multiple technical areas including insulation systems, short-circuit resistance, energy efficiency, and noise reduction—along with innovative manufacturing processes—our company has accomplished significant advancements in high-voltage handling, power capacity, space efficiency, lightweight design, acoustic performance, and energy conservation.

 

1. High Voltage & Large Capacity  
   - Designed to handle extra-high voltage (EHV) and ultra-high voltage (UHV) levels for efficient power transmission.  
   - Supports large power loads with minimal energy loss.  

2. High Efficiency & Low Losses
   - Utilizes advanced core materials (e.g., grain-oriented silicon steel) to reduce hysteresis and eddy current losses.  
   - Optimized winding designs (e.g., disc/helical windings) minimize stray and copper losses.  

3. Compact & Lightweight Design
   - Incorporates molded insulation and compact core structures to reduce size and weight.  
   - Enables easier installation and transportation.  

4. Low Noise Operation 
   - Features step-lap core joints and vibration-damping materials to reduce audible noise.  
   - Ideal for urban and residential installations.  

5. Enhanced Insulation & Cooling  
   - Uses oil-immersed or dry-type insulation for high dielectric strength.  
   - Efficient cooling systems (ONAN, ONAF, OFAF) ensure stable thermal performance.  

6. High Short-Circuit Strength  
   - Reinforced windings and robust mechanical design withstand fault currents.  
   - Prevents deformation under extreme electrical stresses.  

7. Long-Term Reliability & Durability  
   - Corrosion-resistant materials and sealed tanks protect against environmental factors.  
   - Maintenance-friendly design for extended service life.  

8. Smart & Adaptive Features (Modern Transformers)  
   - Integrated sensors for real-time monitoring (temperature, load, partial discharge).  
   - Compatible with smart grid and IoT-based power systems.
