Chapter 3 Lightning Protection

3.1 Cabling Reasonably

In the actual network environment, you may need cable outdoors and indoors, and

the requirements for cabling outdoors and indoors are different. A reasonable cabling

system can decrease the damage of induced lightning to devices.

Note:

It’s not recommended using Ethernet cables outdoors. When cabling outdoors,

please use a signal lightning arrester.

■

Requirements for Cabling Outdoors

■

Aerial cabling without safeguard is not allowed.

■

It’s not allowed cabling down the building to connect network devices in different

floors.

■

Outdoor cables should be buried and paved to the indoor through basement. A piece

of steel wire should be paved underground along the pipe and connected to the

lightning protection terminal of the building for shielding. Before connecting the cable

to the device, install a signal lightning arrester on the corresponding port.

■

When an aerial cable is set up, the cable should be through a metal pipe (15m long

at least) before coming into the building. The two ends of this metal pipe should be

grounded. Before connecting the cable to the device, install a signal lightning arrester

on the corresponding port.

■

It’s not necessary to pave STP cables through pipes. The shielded layer of STP cable

should be well grounded. Before connecting the cable to the device, install a signal

lightning arrester on the corresponding port.

■

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.
