Cable Routing Requirements
l
Before power cables and grounding cables are laid out, the connectors must be
covered by insulation tape.
l
The power cables, grounding cables, and signal cables must be routed separately.
l
When signal cables, DC power cables, AC power cables, and feeders are routed in
parallel along a cable ladder, ensure that a spacing greater than 100 mm is reserved
between different types of cables.
l
If signal cables and power cables need to be laid out in a cross manner, the cross
angle must be 90°.
l
If a cable needs to bend, ensure that the bending radius meets the minimum bending
radius requirement, meaning that the bending radius must be equal to or greater than
20 times of the cable's outer diameter.
