2.4.1 Routing Rules
This section describes the routing rules of cables.
Bundling Cables
Comply with the following rules when bundling cables:
Bundle power cables and signal cables separately.
Bundle cables evenly with equal space between cable ties.
Do not bundle cables too tightly or drag cables.
Arrange all cable ties in the same direction without any sharp edges at the
ends.
Coil the redundant optical fibers and cables.
Turning Cables
Comply with the following rules when turning cables:
To prevent damage to cable cores, avoid bending the cables excessively.
Curvature radius of the cable at the turning point is twice larger than its
diameter. The curvature radius near the connector is four to six times larger
than the cable diameter.
Do not bundle cables at the turning. Arrange the bundled cables close to each
other.
Routing Cables
Comply with the following rules when routing cables:
Decide the specifications, path, cross sectional area, and position of cables
according to the construction drawing.
Arrange cables neatly and avoid damaging the cable sheath.
Route different types of cables separately.
Consider maintenance and expansion in the future.
Ensure that cable connectors made on site are standard, firm and reliable.
Power cables, ground cables, and various signal cables must be connected
firmly and reliably at both ends. Transfer connectors are connected or
screwed firmly.
