Routing Feeders
96
Feeder routing principles
 Note down feeder actual route on paper to avoid rework.
 Rout the feeder neatly without crossing the indoor cabling rack.
 Rout the main feeder along the outdoor cabling rack and the
cabling rack on the tower with no crossing.
 The minimum bending radius of the main feeder should not be less
than 20 times the radius of the main feeder. For one-time bending,
the minimum bending radius is 3.54 inch (90 mm). For multi-time
bending, the minimum bending radius is 7.87 inch (200 mm).
 The maximum spacing between feeder clips is 64.96 inch (1.6 m).
Confidential and Proprietary Information of ZTE CORPORATION

Feeder routing procedure
i. Install a three-feeder clip every 59.05 inch (1.5 m) (or according to
actual installation condition that it is within 64.96 inch) (1.6 m)
along tower cabling rack and indoor cabling rack. Keep spacing as
even as possible and ensure feeder clips installation direction same.
While installing two rows of feeder clips inside same cabling ladder,
keep the two rows parallel and arrange them neatly. Figure 79
shows layout of three feeder clip.
FIGURE 79 - THREE-FEEDER CLIP
ii. Sort the feeders roughly in order.
iii. Fix main feeders from top to bottom and sort them out while
attaching with three-feeder clips. Fasten the feeder clips after
smoothing the main feeders. Keep main feeders flat and straight.
iv. Fix the main feeders with three-feeder clips along the outdoor
cabling ladders.
Hoisting Feeders to Tower
For a tower mounted feeder, use pulley blocks to hoist it. For the
installation, follow the steps below:
1. Ensure that the labels attached at 11.81 inch (300 mm) away from
main feeder both ends 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 409.4 inch (1.5 m) away from the feeder
connector. It helps the staff both on and under the tower in pulling up
the feeder, and prevents the feeder and its connector from colliding
with tower during hoisting process.
4. After hoisting main feeder to the tower top, fix upper end at multiple
points to prevent it from slipping down the tower.
