These are highly reliable, high performance lightning arrester tubes that are used in a variety of protective devices for railroad standard signals, communications and power transforming, and protect people, weak electrical current equipment and signal cables, communication cables and control cables from irregular current from lightning surges that may have been induced along cables, etc., or from the earth potential rise that may occur in the event of a substation malfunction, etc.
●Completely compatible with conventional tubes
●Lower impulse spark -over voltage
●Increased current withstand capacity
●Robust structural strength
●Where the metal electrodes of the conventional tube cases are exposed, this new type has an insulated case, allowing protection against electric shock during maintenance.
