Security features
- Dry technology
Self - healing technology
In the power distribution system, the switch operation will produce transient over-voltage, the peak may reach 3 times the rated voltage. At this point, the weakness of the media will be punctured, specially designed with a metal coating of polypropylene film has a good self-healing function, can make the capacitor to continue normal operation.
- Separate Independent Pressure Isolation Circuit Protection
When the capacitor reaches the service life or over time, overheating, the process of self-healing will continue to occur, the capacitor will produce a very high internal pressure, SIEG capacitor each phase has a pressure-sensitive circuit breaker, when the capacitor inside When the pressure reaches the threshold of the action, the top of the capacitor will be slightly raised, so that the pressure-sensitive circuit breaker action, which will disconnect the capacitor from the grid to avoid accidents.
