1. Bushing: cold-pressed, anti-pollution type bushings, creepage distance is not less than 31mm/kV.
2. Liquid medium: 100% benzyl toluene (M/DBT) is used, which has excellent low temperature performance and partial discharge performance.
3. The main insulation adopts composite insulation structure, which ensures excellent electrical performance and has certain mechanical strength, ensuring that the ground insulation of the capacitor complete set is 100% reliable without protection.
4. Good sealing performance: annual leakage rate is less than 0.1%, through automatic argon arc welding, vacuum leakage test, hot aging and other measures to ensure the sealing performance of the capacitor.
5. Partial discharge level: the extinguishing voltage is not less than 1.5Un, and each capacitor is tested for partial discharge during factory test.
