SPARK GAPS are highly recommended as safety devices for protecting and bridging Insulating Joints from tension surcharges due to lightning strikes and to prevent any risk of ignition in explosion-hazard areas (ATEX).

SPARK GAPS are available for above ground and underground installation and can be supplied with Zunt Insulating Joints, on request. Spark gaps are supplied as a separate accessory to be positioned on the insulating joints after their installation on site.
