In the past, ex isolating spark gaps for protecting insulating joints were usually installed underground or in ex zones. Maintenance and inspection were, as a result, time intensive and sometimes involved extensive digging, which was expensive.
The answer is the EXFS Coaxial Connection Box which can be installed above the ground or outside ex zones.
Safe inspection - outside the ex zone
The EXFS Coaxial Box protects the insulating joints of pipelines in potentially explosive areas. To facilitate regular inspections, the Coaxial Connection Box with integrated ex isolating spark gap EXFS 100 is installed outside the ex zone. Thus, inspection is quick and easy. This protection solution is already in use in the natural gas transfer station of the MONACO pipeline!
