Binding Rule
1
Power cables and signal cables are bound separately with a distance above 150 mm.
2
Both ends of a cable are labeled. Labels are clean and correct, and provide concise and
understandable description.
3
Cable ties are neatly cut without sharp burs, evenly distributed, bound to a proper strength,
and fastened towards the same direction if possible,
as shown in the following figure.
4
Each bundle contains no more than 15 cables, and cables are neatly bound.
5
Extra cables are coiled neatly and easy to find.
6
Cables on the surface of a large cable bundle are neatly organized without unnecessary
crossover.
7
Cables are arranged in distinct layers and crossovers are avoided if possible when cables in
different colors are bound together,
as shown in the following figure. Cables are arranged by
thickness when arrangement by thickness conflicts with arrangement by color.
8
Cables are reliably bound along the route, and the binding interval meets the requirements in
following table
