It is used for the indirect connection of an external lightning protection system to other close metallic parts, where a direct connection
is not allowed due to operating conditions: earthing systems of heavy current installations, telecommunications systems,
auxiliary and rail earthing bars of earth short-circuit breakers triggered by the voltage, AC and DC rail earthing bars, measurement
earthing bars for laboratories, installations with cathodic protection and stray current systems, service entry poles for external LV
cabels, by-pass of isolated fl anges and isolated connections to pipelines.
