HVI power Conductor for EX zones 1 and 21

Reliable external lightning protection solution for systems in hazardous areas: HVI power Conductor

Potentially explosive atmospheres where a lightning strike e.g. to storage facilities or silos can have fatal consequences can be found in many industries (process technology, biogas plants, storage facilities, silos, storage tanks).


Uncontrolled sparking resulting from lightning strikes may cause an explosion which presents a danger to persons, animals and the environment and entails high costs.
Ex zones - danger zones listed in explosion protection documents – must be taken into account when designing and installing lightning protection systems. In general, non-sparking lightning protection and equipotential bonding measures must be implemented in Ex zones 1 and 21.

The high-voltage-resistant insulated HVI power Conductor is a reliable and tested solution for discharging lightning currents in Ex zones 1 and 21

This conductor is an ideal solution for all classes of LPS. In conjunction with the associated accessories, it can even be used for class of LPS I since the entire system is tested with lightning impulse currents of 200 kA (10/350 µs).

Highlights:

  • Separation distance is 20% higher (90 cm instead of 75 cm (air) /180 cm (solid material)) compared to HVI long Conductors
  • Easy and fast installation thanks to new sealing end spring
  • Low area exposed to wind since the conductor is integrated in the supporting tube
  • Discharge of lightning currents without sparking
  • TÜV-certified for use in Ex zones 1 and 21

HVI power Conductor w. preassembled head unit D 27mm Cu L 6,0m black

Air-termination mast with HVI power Conductor (high-voltage-resistant, insulated down conductor), for keeping the separation distance from conductive parts according to IEC/EN 62305-3 in order to prevent dangerous flashover between parts of the external lightning protection system and indoor conductive parts (electrical installation, pipes, etc.). In order to avoid creeping discharge, the HVI power Conductor has a special outer sheath which makes it possible to discharge high lightning impulse voltages to a reference potential. Pre-assembled (black), with head piece and connection element (connection element enclosed loose). Equivalent separation distance s ≤ 90 cm (in air), s ≤ 180 cm (solid material).

HVI Ex W70 holder f. Conductor D 20mm distance 70mm w. fixing plate StSt

Conductor holder for installation of the HVI Conductor in explosion hazardous areas Ex zone 1 (gases, vapours, mists) as well as Ex zone 21 (dusts). The special installation conditions safely prevent electric sparks to neighbouring metal parts when lightning current flows through the HVI Conductor. Design with spacer sleeve 70 mm, for fixing on metal construction parts (e.g. façades).
