⚙️ Product Description
This series of Current Transformers includes products such as LB-60W2, LB-66W2 (LB-72.5W2), LB9110W2 (LB9-126W2), LB9-120W2 (LB9-123W2), and LB-132W2, LB-138W2 (LB-145W2). These are designed for electric current measurement, energy measurement, and relay protection in power systems with voltages ranging from 60kV to 145kV and frequencies of 50Hz to 60Hz. All products comply with GB 1208 and IEC 60044-1 standards.
🌟 Key Technical Advantages:
- Superior Sealing: Components are not exposed to air, ensuring longer service life and better performance.
- Anti-Corrosive Design: Oil tanks made of anti-corrosive aluminum alloy eliminate partial whirlpool heat and prevent rust.
- High Strength Insulation: Porcelain bushings made of high-strength porcelain spliced with the oil tank for a compact and beautiful structure.
- Advanced Drying Technique: Utilizes profiling heat conduction and high-degree vacuum drying to maintain insulation integrity (dielectric loss below 0.3%).
- Precision Testing: Oil draining valves allow for syringe sampling to ensure the precision of transformer oil tests.
