HGS 100 Ex

HGS 100 Ex – Separating high power gas discharge tube HGS 100 Ex for use in explosion hazards areas. It is intended for equipotential bonding of the installation parts of buildings or technological entities which are not interconnected operationaly. In case of p.d. (potential difference) origin between those parts, the high power gas discharge tube ignites and interconnects both parts for a transient time (typical value of internal resistance at startup of HGS100 Ex is 0,001÷ 0,002Ω). Recommended installation is inside of the buildings, outdoors, in the damp rooms as well as in the subterraneous areas.

It is an explosion-proof gas discharge tube with flexible connecting cable for equipotential bonding acc. to IEC 62305-1:2010 and also for the use in IT installations acc. to IEC 60364-5-54:2011. It complies with IEC 60079-0:2011, IEC 60079-18:2014 and IEC 60079-31:2013 standards. It is recommended for insulated flanges and insulated screw joints bridging in cathodic protected parts of industrial technology.
