Statics, Interference Lightning and Surge Protection
This product adopts TVS plate lightning protection technology to avoid damage caused by pulse signal that is below
3000W, like instantaneous lighting stroke, surging, etc. According to the actual outdoor situation, necessary protection
measures must be taken, besides ensuring the electrical safety.
!
The distance between signal transmission wires and High-‐voltage equipment or high-‐voltage cable is at least 50m.
!
Outdoor wiring should better be routed under eaves as much as possible.
!
In the open field, wiring should be buried underground in sealed steel pipe, and the steel-‐pipe should be one-‐point
grounding. Overhead routing method is forbidden.
!
In strong thunderstorm area or high induction voltage areas (such as high-‐voltage transformer substation), high
power lightning protection apparatus and lightning conductor are necessary to be added.
!
The design of lightning protection and grounding of the outdoor devices and cables should be considered together
with the lightning protection demand of buildings. It also must conform to the related national standards and
industrial standards.
!
The system should be equipotential grounded. The grounding equipment must conform to the demands of system
anti-‐jamming and electrical safety both and it must not appear short circuit or mixed circuit with the zero
conductor of strong grid. When the system is grounded alone, the resistance should be no more than 4Ω. The
sectional area of the grounding cable should be no less than 25mm2. For grounding instructions, please refer to the
Installation Manual of Speed Dome.
