DESCRIPTION
Isolating Spark Gaps are used for indirect connection/earthing of functionally separate system parts at lightning strikes.
APPLICATION(S)
- Indirect connection/earthing of functionally separate system parts at lightning strikes.
- Lightning equipotential bonding according to IEC 62305 for hazardous areas.
- Bridging insulating pieces, insulating flanges, etc in cathodic protected pipe sections.
- Safe operation in explosion protection zone 1 &2 (gasses) or 21 & 22 (dust).
TECHNICAL INFORMATION
Isolating spark gaps are used when conductive parts of installations situated in hazardous areas cannot be connected directly to each other. The low sparkover voltage of the spark gaps have proved themselves for protection, especially for separate installation parts with low insulation resistance against each other. The EXFS 100 is the first isolating spark gap for use in potentially explosive atmospheres which withstands high loads in accordance with DIN EN 50164-3 (lightning current carrying capability 100kA, Class H) Accessories include connection cables and connection brackets. Many spark gaps are available to suit any application.
