Figure 4-95 Cable organizer
Route and lay out a large number of cables in different areas to ensure neat
cabling and facilitate cable search and maintenance.
Route several flat cables along the same path and then overlap them as one.
Arrange cables on distinct layers and prevent cable tangles that are avoidable
when cables in different colors are bound together, as shown in
Also comply with these rules when cables of different thickness are bound
together. Arrange cables by thickness when arrangement by thickness
conflicts with arrangement by color.
Figure 4-96 Binding cables in different colors
Separate AC and DC power cables from diverse non-shielded signal cables.
Keep the cable spacing greater than 100 mm or use grounded metal for
isolation purposes. Do not bind the cables together. Preferentially route the
cables along different sides of cabinets.
You are advised to route network cables and optical cables separately.
Unless otherwise specified in a design file, ensure that the bend radius (R) of
a cable meets the following requirements:
– Common cable: R ≥ 3d
– Optical cable: R ≥ 40 mm
NO TE
R indicates the bend radius, and d indicates the cable diameter.
Reserve slack at cable connection positions to facilitate connection and
disconnection and to prevent stress. Do not leave the cables tight and prevent
connector misalignment, as shown in
