33KV Surge Arrester
33KV Surge Arrester Description
SPD (Surge Protective Device or called surge arrester) is an
appliance designed to protect electrical devices from voltage
spikes. A surge protector attempts to regulate the voltage supplied
to an electric device by either blocking or by shorting to ground
voltages above a safe threshold. We have spark gap, MOV and Spark
tube type for different protection area.
For the whole building lighting protection, 30kA-60kA, 40kA-80kA,
50-100kA, are available, however, 30kA-60kA is the most common one.
As we know, one building have two unita, one is A, the other one is
B, for A or B, surge arrester 20/40kA will be your best selection.
What's more, we also can provide the one such as surge arrester
5-10kA,especially 10-20kA to strongly protect the single room,
5-10kA to protect a single unit electric device.
