are not damaged or pressed.
2. For the antenna feeder to be installed on the tower
1) Use roller support, pulley block and hoisting rope to lift one end of the feeder to
the tower top. The person on the ground cuts the feeder to the length with which
the feeder can reach the lightning arrester frame inside the equipment room (plus
certain redundancy). Attach temporary labels to the lower part of the feeder.
Once the feeder enters the equipment room, attach a formal label to it.
2) It is better to make the upper connector of the main feeder before hoisting it to
reduce the time that the staff works at heights and to better ensure the
installation quality of the feeder connector.
10.4.7.4 Raising the Main Feeder Cable of the Iron Tower
Caution:
During the hoisting, rough operations are not allowed, lest the sheath of the main
feeder be damaged or scratched. The partial damage of a single main feeder will cause
the whole cable be rejected as useless.
Take precautions for personal safety when hoisting the feeders.
If the antenna feeder system is to be installed on an iron tower, a pulley block should
be used to hoist the primary feeder cables, as shown in Fig. 10.4-12. For the installation,
you should follow the steps below:
1. Check again that the main feeder labels attached 0.3 m away from both ends of
the main feeder are correct.
2. Wrap the main feeder connector made under the tower with flax (or antistatic
packing bag together with foam) and strap it tightly.
3. Knot and fix the hoisting rope 0.4 m and 3.4 m away from the feeder connector
to help the staff both on and under the tower pull up the feeder and to prevent
the feeder and its connector from damage caused by their bumping into the
tower during the hoisting process.
4. Hoist the feeder to the tower platform and fix the upper end of the cable to a
proper place at several points, lest the cable fall down from the tower.
