AT-050K spark gap for earth bonding

The lightning protection regulations earth connections, i.e. those relating to both the earthing system and the lightning protection system. In this way, we avoid serious problems due to resistive earth couplings.
However, on some occasions this connection cannot be made as, for example, it may cause corrosion problems. In these cases, the AT-050K is the most appropriate means of joining the different earth connections.
In normal conditions, this protector keeps the earth connections isolated, thus avoiding corrosion problems. When a discharge occurs and the voltage increases in the earth connections, the spark gap will activate, directly joining the earth connections and thus preventing current passing from one to another through equipment or internal installations.


Thiết bị đẳng thế AT-050K dùng cho hệ thống tiếp đất chống sét và an toàn điện


AT-050K spark gap for earth bonding has two AT-020F clamps for installation. It is advisable to carry out installation in a specific earth pit.
