Installation of the HVI

holder distance of 500 mm; wall distance of 85 mm

Fig. 4 shows a typical application at a metal pipe, e.g. a mobile phone mast.
If metal conductor holders of type HVI
(Part No. 275 454) and a maximum installation distance ≤ 500 mm (see Fig. 4) are used, discharges can
be reliably prevented. The conductor holders are fixed by means of a pipe clamp (Part No. 106 323; see
Fig. 7, page 10).
