Description

The product is used for physical isolation between two networks, effectively solves the mutual interference between the two systems, suppresses the common mode overvoltage (such as induced lightning overvoltage), and is widely used in industrial field network signal isolation, security protection and so on. It is an indispensable guarantee unit module for automatic control system and network communication system. The product is divided into 10 ≤ 100m and 1000m categories.

Equal potential lightning protection is to protect lightning in an "equal potential" way, which does not depend on the ground wire, but can block and eliminate lightning. That is, in the protected equipment, each port is connected to the "equal potential" arrester, at this time, no matter whether the lightning pulse invades from any external connection of the equipment, the lightning arrester is processed by internal potential balance, so that each port of the equipment and between the core and skin of the same port reach an equal potential state with omni-directional potential difference of "zero". As a result, the lightning strike current can not flow into the equipment, so that the equipment is protected, similar to the bird station high-voltage line, substation maintenance workers wearing special work clothes with good conductivity are not electrocuted.
