In case of potential difference origin between two sides of insulation flanges, the high Spark gap ignites and interconnects both parts for a transient time (typical value of internal resistance at startup of HGS100 Ex is 0.001вЂ¦ 0.002). It is recommended for insulated flanges and insulated screw joints bridging incathodic protected parts of industrial technology. It complies with EN 50014 and EN 50028 standards. HGS100 Ex is an explosion-proof gas discharge tube Spark gap with flexible connecting cable (varies to meet application requirements) for equipotential bonding acc to IEC 61024-1 and also for the use in IT installations acc to IEC 6. In these locations, in the event of a lightning strike on to any above ground pipe work or connected structure, or an electrical fault causing a voltage surge on the pipe, a flashover across the insulating components to the flange could occur. In order to limit the extent of the appliedcathodic protection and prevent the loss of protective current to other buried metallic structures. This, in turn, requires the use of insulating flanges at terminal points on the pipeline system, such as at tank farms, governor stations, etc. 100.000 h Weight m 550 g Article number 10 201Д«uried pipelines for oil, gas and other inflammable materials are normally provided withcathodic. lightning impulse current (10/350) Iimp 100 kA - charge Q 50 As - specific energy W/R 2500 kJ/ Voltage protection level at Iimp UP < 1 kV Insulation resistance at 100 V DC Ri < 1 G Capacitance at 1 MHz C 5 pF Casing corundum/binary resin with an external steel coat, resistant to climatic effects Protection type IP67 Operating temperature range J -40вЊ. discharge current (8/20) Imax 100 kA Nominal discharge current (8/20) In 75 kA Max.

The entire piping system must be treated not only against lightning strikes, but also equipped with isolating gas discharge tube for equipotential bonding (HGS100 Ex) at all technological facilities of the system. The two major areas of growth are the Asia Pacific Region, (34,295 miles) and the North America Region (31, 951 miles). In addition to the substantial size of the present world pipeline infrastructure, it is estimated that the combined global growth of the pipeline infrastructure under construction or in the planning cycle for 2012 will be 118,000 miles. This vast size provides a high probability that there will be Iightening strikes on or near the natural gas infrastructure on a reccurring basis.

This infrastructure encompasses approximately 310,000 miles of natural gas transmission pipeline, 1.9 million miles of natural gas distribution pipelines approximately 3,000 compression stations, and the associated electronic supervisory control and data acquisition (SCADA) systems used to control the infrastructure. The natural gas pipeline infrastructure, including transmission lines, distribution lines, processing plants, compressions stations, gate stations, and underground storage facilities, is susceptible to Iightning strikes. It is recommended for insulated flanges and insulated screw joints bridging in cathodic protected parts of industrial technology. to IEC 61024-1 and also for the use in IT installations acc. It is an explosion-proof gas discharge tube with flexible connecting cable for equipotential bonding acc. Recommended installation is inside of the buildings, outdoors, in the damp rooms as well as in the subterraneous areas.

(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 0,001Г· 0,002О©). It is intended for equipotential bonding of the installation parts of buildings or technological entities which are not interconnected operationaly. HGS100 Ex - Separating high power gas discharge tube HGS100 Ex for use in explosion hazards areas.
