HVI power Conductor
        HVI     power Conductor
        The HVI power Conductor is the most powerful variant of the high-volt-
        age-resistant, insulated down conductors (HVI Conductors). Unlike the                           s s
        standard HVI Conductor, it allows one to maintain an equivalent separa-
        tion distance of 0.9 m in air and 1.8 m in solid material. It is particularly                ≤ 90 cm
        important to point out that the HVI power Conductor and the correspond-                      < 75 cm
        ing components are tested for a lightning current carrying capability of
        up to 200 kA (10/350 µs) based on EN 62561-1. Therefore, this type of
        conductor may be used for all classes of LPS (I-V).

        This conductor is installed, above all, on buildings such as hospitals,
        computing centres or silos where large separation distances need to be
        maintained due to the building dimensions (height). Moreover, the con-
        ductor routing to the earth-termination system can be longer.
        The conductor can be installed inside a stainless steel or aluminium
        supporting tube. The internal sealing end spring element automatically
        contacts the semi-conductive sheath and thus provides the sealing end.
    HVI   power Conductor  The functional equipotential bonding is directly connected to the metal
        supporting tube and the structure. When using GRP/Al supporting tubes,
        another HVI power Conductor can be installed outside using a connection
        kit.
        HVI power Conductor (pre-assembled)
        In case of the pre-assembled HVI power Conductors, inside as well as
        outside installation, the head piece is already assembled and shrink
        wrapped.  The other conductor end can be exactly positioned to suit
        the structure of system using the loosely delivered connection element.
        Minimum order length is 6 m, additional conductor lengths in steps of
        0.5 m (max. 35 m). Conductor length to be indicated when ordering.

        HVI power long Conductor (on plywood reel / cut to length)
        The  HVI  power  long  Conductor  for  on-site  assembly  is  available  in  a
        length of 100 m on a disposable plywood reel (diameter approx. 900 mm,
        width approx. 485 mm) or cut to length (6-35 m or 36-80 m). The installer
        determines the required lengths, cuts to length and assembles the sealing
        ends on site.
