At present,the international and domestic lightning protection theories and project are getting more prevailing to share-earth and equal electric potential connection.Share-earth is to join many different protect lightning place a lot of of earth devices with different characters together and make it become an equal electric potential object. Equal electric potential connection is to join the metal material nearby the building such as reinforcing bar in the concrete, running water pipe , gas pipe and other metal pipelines , Line zero of the power system ,etc. with a electric connection ( welding or reliable electric connection), make the whole building become such electric potential body as a good equal electric potential object. When the thunder and lightning is coming to attack, because the region within and near the building are equal electric potential, there won't take place the accident that the equipments in the building are strike back or the people are strike by lightning.
The products of Cougar adopt equal potential connection,so the requisition for earth resistance of the building can be relaxed. The point will be particularly important to the region with high resistivity soil such as the aridity, desert,etc. | |
