TLB Series
Disconnector

As a special supporting product of lightning aresters, the disconnector can be used in series with lightning arresters. 

In the event oflightning arrester failure,it can quickly act and remove the faulty ightning arrester from the power grid. At the same time, it providesclear disconnection signs, making it easy for maintenance personnel to identify the fault point and replace the arrester. 

On the other hand, when the lightning arrester is working normally, the disconnector does not act and exhibits low impedance, which does notaffect the protective characteristics of the lightning arrester. 

The installation of lightning arresters with disconnectors is the only way to truly achieve safe, maintenance free use, convenience, and reliability.
