Cable tray.
See Figure 5.3. For all interconnecting wiring between the transformer cabinet and
transmitter cabinet, Nautel recommends (and can provide) a cable tray support system (Nautel Part #
207-8385-08, see
Table 5.4 on page 5-8 ). Other options include armoured cable such as Teck90 or
conduit.
The advantages of using a cable tray system are:
• established, approved, reliable method to route high-current wiring
• easily accommodates top entry into transmitter cabinets (cable tray is suspended from
ceiling) and supports wire weight
• fuse assembly on side of transformer cabinet pre-fitted to accept 4” x 18” cable tray;
each transmitter cabinet pre-fitted to accept 4” x 6” cable tray
Cable tray lengths are dependent on the distance between the transformer cabinet and transmitter
cabinets. All cable tray parts can be purchased as part of Nautel’s Cable Tray Parts Kit (Nautel Part
# 207-8385-08). Refer to Figure 5.3 of this manual and to the
NX100 Installation Manual for details on
installing the cable tray.
Plan your cable tray installation to ensure its position does not interfere with any exhaust ducting
being used see
Section 3, “Physical requirements” .
