Keep the bound cables neat. The horizontal
cables should be bound with even distance
between cable ties.
Do not join several cable ties to make a
longer one and bind cables with it;
otherwise, the tensity may be reduced.
The cable ties are arranged in good order.
The extra parts of the ties are cut from the
root without leaving sharp points.
When binding cables, abide by the following
rules for the distance between cable ties:
When the diameter of the cable bunch is
less than 10 mm, the distance between
cable ties should be 150 mm;
When the diameter of the cable bunch is
between 10 mm and 30 mm, the distance
between cable ties should be 200 mm;
When the diameter of the cable bunch is
equal to or larger than 30 mm, the distance
between cable ties should be 300 mm.
When binding bent cables, do not bind
them midway through the bend; otherwise,
the cable cores may be broken.
The bending radius of cables (R) shall meet
the following requirements (“D” refers to the
cable diameter):
Cables for general use: R ≥ 2 D
；
RF cables: R ≥ 15 D in common
conditions; R ≥ 10 D in extreme
conditions.
The cables inside the cabinet should be
arranged from far to near. That is, lay the
cables to the farthermost end first, putting
them at the bottom layer in the wiring area.
Avoid crossing or twisting cables whenever
possible.
