Figure 4-17 Cable binding example I
z The radius of the curve at which a cable is bent should be no less than twice of the
cable’s diameter. At the point where a cable runs out of a connector, the radius of
the curve at which the cable is bent should be no less than five times of its
diameter.
z Cables of different type (that is, power cable, signal cable, grounding cable, etc.)
should run and be bound separately in a cabinet. They cannot be bound together.
If they are close to each other, you can cable them in a crossing way. For parallel
cabling, the space between power cable and signal cable should be no less than
30mm;
z The cable binding rack and cable channel inside and outside a cabinet should be
smooth and stretch no sharp points.
z The metal hole through which a cable runs should have a smooth and fully surface
or an insulating bush;
z Use the right type of ties to bind the cables. Do not bind any cables with tied ties.
The following types of ties are provided: 100*2.5mm, 150*3.6mm, 300*3.6mm,
530*9mm, and 580*13mm;
z Bind the cables with ties and cut the extra parts. Trim the cut and leave no sharp
points. See the following figure:
