Routing Feeders
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).
