With years of accumulation in the transformer industry and strong technological innovation capabilities, HZEC products are sold to the Middle East, North America, South America, Europe, Southeast Asia, Africa, and other regions, covering more than 40 countries.
The capacitor is composed of core, shell, outgoing porcelain sleeve, etc. The box wall is welded on both sides for installation, and one side is equipped with a ground bolt. The core of a capacitor is composed of a number of components and insulating parts, in order to adapt to various voltages, the core is composed of a number of small components in parallel and then connected in series.
The capacitor is equipped with discharge resistance inside, and the shell is formed and welded by stainless steel plate.
Standards:GB/T 11024; DL/T 840; IEC 60871

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.
