CKG4-10kV(12kV) High Voltage Vacuum Contactor
This series of high-voltage vacuum contactors, the AC vacuum contactors are suitable for power network system with AC 50-60HZ, 6kv(7.2kv), 10kv (12kv) main circuit rated voltage , and rated current from 160A to 1600A. This series of contactor is being applied in long-distance connection and breaking, as well as the frequent starting and controlling AC motors, transformers and capacitor banks and other occasions.
Good triphase synchronization, and stable mechanical characteristics.
Small closing bounce.
The resistance of the main circuit is ≤ 200 (μΩ) and the reliability is high.
Higher cost performace.
