Surge Arrestor installed between communication equipment and coaxial cable connector or between two
communication equipments can protect communication equipment from damage caused by transient state voltage formed by thunder induction. It adopts quarter-wave technology, is designed according to VSW theory and frequency spectrum of lightening 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 equipments and lightening sensitivity.

It‘s an electrical appliances to protect the electronic equipment against lightning overvoltage transient protection, 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.
