Applicable Scope
This product is widely used for preventing lightning direct stroke to the following area:
Telecom, Petroleum, Chemical, Electric Power, Meteorology, Microwave Communication, Broadcasting, Oil Tank Farm, Electric Transformer Substation, Aviation, Financial System, Network, Industry and High-rise Building
Usage
Conduct the direct lightning strokeLeader Stroke in advance, conduct the electrical currents to ground, no phenomenon of shielding failure nor side strokeLow grounding electrical currents, decrease the occurrence rate of “counter strike” which caused by potential difference that caused by enormous electrical currents flow to ground. Weaken the phenomenon of induced over-voltage caused by the enormous electrical currents presenting to the grounding weir.
