These are designed for electric current measurement, energy measurement, and relay protection in electric power systems with voltages ranging from 60 to 145kV and frequencies of 50 to 60Hz. All products comply with GB 1208 and IEC 60044-1 standards.
Product Details
Key Technical Features
  • Superior Sealing: Components are not exposed to air, ensuring better performance and longer service life.
  • Advanced Structure: Utilizes a national patent-confirmed design with an anti-corrosive aluminum alloy oil tank to eliminate partial whirlpool heat.
  • High Strength: Porcelain bushing made of high-strength porcelain, integrated with the oil tank for high mechanical strength and beautiful appearance.
  • Reliable Insulation: Advanced drying techniques and high vacuum drying ensure dielectric loss remains below 0.3% under 10kV.
  • Precision Testing: Oil draining valve allows for precise oil sampling to ensure transformer oil test accuracy.
