Surger Arrester

A lightning arrester is connected between the cable and the ground, usually in parallel with the protected equipment. It can effectively protect communication equipment. Once an abnormal voltage occurs, the lightning arrester will act and play a protective role. When the communication cable or equipment is operating under normal working voltage, the lightning arrester will not act and is regarded as an open circuit to the ground. Once a high voltage occurs and threatens the insulation of the protected equipment, the lightning arrester will act immediately, guiding the high-voltage impulse current to the ground, thereby limiting the voltage amplitude and protecting the insulation of the communication cable and equipment. When the overvoltage disappears, the lightning arrester quickly returns to its original state, allowing the communication line to operate normally.
