Lightning arresters and Surge Suppressors

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
arresters equipment must be installed.
Take the building lightning proof requirements into account to design the lightning arrestors 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 circuit with high voltage electricity net. When the system is grounded
separately, the resistance of down conductor should be ≤ 4Ω and the sectional area of down conductor should be
≤25mm2.
