Strong current and weak current cables are routed separately.
The power cables, ground cables, and signal cables are
bundled and routed separately (with a spacing of more than
30 mm) to prevent electrical or magnetic interference. Use
shielded cables in places with strong interference.

General
When routing cables in walls, place the cables in the cable
troughs or pipes and fix the cables using pipe straps. For non-
metal corrugated pipes, the fixing distance should be about
1000 mm.

All outdoor connectors or feeder cable connectors are
properly sealed to prevent water. Wrap the cable using one-
layer PVC insulation tape, three-layer waterproof tape, and
then three-layer PVC insulation tape. The tape shall be
attached evenly and neatly. The network cables shall be
covered with waterproof PG tubes.

Cable connectors are secured on cables and sealed to prevent
water intrusion. The outlets of cable conduits on a wall are
sealed by waterproof and flame-retardant materials. Drip
loops meeting the minimum bending radius requirement are
made on the network cable segment that stretches indoor.

Surge protection measures are taken in the places where the
outdoor APs are installed. The outdoor APs, antennas, and
signal cables are deployed within 45-degree protection area
of a lightning rod.

The bare wires of network and feeder cables should be
covered by the winding pipes, flexible metal conduit, PVC
pipes, or galvanization pipes. The cable outlet and inlet are
sealed to prevent dusts.
