Isolating spark gaps

Isolating spark gaps for aboveground and underground installation are used to indirectly earth and connect functionally isolated parts of installations under lightning conditions.

TFS / KFSU

For lightning equipotential bonding according to IEC 62305 as well as for use in IT installations according to IEC 60364-5-54.

EXFS L / EXFS KU

For bridging insulating flanges and insulating glands in cathodically protected pipe sections (e.g., pipelines or LPG plants) in hazardous areas in case of surges and lightning currents.

EXFS 100 / EXFS 100 KU

For bridging insulating flanges and insulating glands in cathodically protected pipe sections (e.g. pipelines or LPG plants) in hazardous areas in case of surges and lightning currents.
  • Class (lighning current carrying capability) H (100 kA)
  • Particularly low sparkover voltage
  • ATEX and IECEx approvals for zone 1 and zone 21

EXFS Coaxial Connection Box

Connection box for coaxial connection of the integrated Ex isolating spark gap for bridging insulating joints and flanges in cathodically protected pipe sections of pipelines.

Protective Spark Gap

Protective spark gap in closed design with plastic sheath for indirect connection of an overhead line roof pole to the external lightning protection system.
