4.4 Cabling safety
The signal transmission lines must keep a distance of at least 50m from high-voltage devices or high-voltage cables.
Outdoor cables should be laid under eaves if possible.
In open fields, cables shall be laid in sealed and earthed underground steel pipes and aerial cabling is forbidden.
In areas with strong thunderstorms or areas with high induced voltage (such as: high-voltage substations), measures like additional installation of
high-power lightning protection devices and lightning rods must be adopted.
The anti-lightning and earthing design of outdoor devices and lines shall be considered together with the anti-lightning requirements of buildings in a
unified way and meet the requirements of applicable national standards and industrial standards.
The system must be equipotentially grounded. The earthing devices must meet the dual requirements of anti-jamming and electrical safety of the system
and may not be connected to the zero line of a high-voltage power grid in a short circuit or mixed manner. When the system is separately grounded, the
ground impedance shall not be greater than 4
Ω
and the section area of the earth conductor shall not be greater than 25mm
2
.
This product adopts TVS plate electrode lightning protection technology and may effectively prevent the damage of the device caused by instantaneous
lightning strikes, surges and other types of impulse signals at or below 1.5KW, necessary protective measures shall be provided during outdoor
installation according to the actual condition and on the precondition of assuring electrical safety.
