High Voltage Surge Capacitor
Introduction:
Surge capacitor is also called protective capacitor,widely being used to restrain switching overvoltage and atmosphere overvoltage. Usually, it is connected with a high voltage resistor in series to combine a RC absorb device.It can absorb the switching overvoltage caused by switching of vacuum switch.
A surge capacitor, also known as a surge suppressor or surge protector capacitor, is an electrical component used to protect electronic devices and electrical equipment from voltage spikes or transient overvoltage.

Model Selection
When the surge capacitor works as over-voltage absorbing device of RC in series,it is commonly with the high-voltage resistor of not less than 200W and 100Ω. The resistors can be fixed in the top of capacitor's bushings,but not standing the mechanical stress.
Note:If you could not decide the model selection,please feel free to contact us.
We accept OEM business. If you have requirement for your new build panels, we can give a good price.
If it is retrofit project,please advise the original capacitor name plate, drawing and the reason of replacement. Such, we can recommend you replacement solution.

FAQ
Why do we use surge capacitors?
These power quality problems like voltage spikes or surges, which can occur due to lightning strikes, power grid fluctuations, or other electrical disturbances are can be protected by Sanhe surge capacitors.
How does surge capacitor protect loads?
The surge capacitor works by absorbing and dissipating the excess energy from the transient voltage spikes, diverting it away from the connected devices. It can act as a temporary storage for the excessive electrical energy and then release it slowly to the ground or back into the electrical system. This helps to maintain a more stable voltage level and prevent it from reaching dangerous levels that could damage the equipment.
