Surge Arresters

A surge protector 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. The surge protectors are inserted between the coaxial cables and the equipment in order to protect the antenna transmission lines, Base stations, Radio equipment and others.
