: Lightning Proof and Surge Signal Proof
The product adopts TVS lightning proof technology to prevent from damage by lightning strike below 1500
W and impulse signals such as surge; but it is also necessary to abide by the following precautions to ensure
electrical safety based on practical circumstances:
Keep the communication cables at least 50 meters away from high voltage equipment or cables.
Make outdoor cable laying-out under eaves as possible as you can.
In open area shield cables in steel tube and conduct a single point ground to the tube. Trolley wire is
forbidden in such circumstances.
In strong thunderstorm or high faradic zone (such as high voltage transformer substation), extra strong
lightning proof equipment must be installed.
Take the building lightning proof requirements into account to design the lightning proof and
grounding of outdoor equipment and cable laying-out in accordance with the national and industrial
standards.
The system must be grounded with equal potentials. The earth ground connection must satisfy the
anti-interference and electrical safety requirements and must not short circuited with high voltage
electricity net. When the system is grounded separately, the resistance of down conductor should be
≤
4
Ω
and the sectional area of down conductor should be
≤
25mm2.
