Details
Ex isolating spark gaps of the EXFS L / EXFS KU product line are used when electrically conductive parts of installations cannot be directly interconnected in hazardous areas, for example, in case of cathodically protected pipeline sections.
ATEX and IECEx-certified EXFS L and EXFS KU spark gaps provide approved safety in accordance with harmonised European standards.
The arc-resistant tungsten / copper electrodes ensure a long service life of the Ex spark gaps.
The approved EXFS L type with flexible cable connection quickly adapts to any application environment. The prewired spark gaps feature connecting cables of different lengths with cable lug, screw and M10 nut. The flat or angled connection brackets (IF), which are available as accessory, allow to easily connect the spark gap to pipeline flanges.
The EXFS KU type is enclosed by a water-proof PVC sheath and is thus ideally suited for underground installation on insulating couplings.
