Requirements for Cabling Indoors
■
When cabling indoors, keep a certain distance away from the devices that may cause
high-frequency interferences, such as down-conductor cable, powerline, power
transformer and electromotor.
The main cable should be paved in the metal raceway of the access shaft. When
■
cabling, keep the loop area formed by the cable itself as small as possible.
Requirements for the distance between Ethernet cable and other pipelines are shown
■
in the table.

height.
Requirements for the distance between Ethernet cable and high-power electric devices

are in following tables.

Note:
The above minimum net length/height is required when metal raceway is not
used. If any requirements cannot be met, you can add a steel tube or metal
raceway for shielding.
