A surge arrester is a protective equipment installed between communication equipment and coaxial cable connector or between two communication equipment‘s to protect communication equipment from damage caused by transient state voltage formed by lightning induction. It adopts quarter-wave technology, is designed according to VSW theory and frequency spectrum of lightning wave. It has features of quick reaction, big current passing capacity, wide frequency band, low VSWR, low insertion loss, easy installation and free maintenance. It can be used to meet protection requirements of various communication equipment‘s and lightning sensitivity.
An electrical appliance used to protect electronic equipment against lightning overvoltage transients. It is usually connected to wires (power phase line, signal line, zero line) and ground between being protective devices in parallel, when the lightning over-voltage the value of the required actions voltage, arrester immediate to limit over-voltage amplitude lead to protection equipment and systems, enabling the system to work properly.
