Product Code : HGS 100EX
Product Description

We offer our clients a premium quality HGS100 Ex - Separating high power gas discharge Piping System that is used in explosion areas. Proposed for equi-potential bonding of the installation parts of buildings or technological entities, this piping system is manufactured with high precision to ensure its quality and excellent performance. In this piping system the high power gas discharge and tube ignites and interconnects origin parts of two objects, both parts for a transient time (typical value of internal resistance at startup of HGS100 Ex is 0,001÷ 0,002Ω).

General specifications:


  • 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 equi potential bonding acc. to IEC 61024-1
  • Also for the use in IT installations acc. to IEC 60364-5-54
  • Complies with EN 50014 and EN 50028 standards
Recommended for insulated flanges and insulated screw joints bridging in cathodic protected parts of industrial technology
