          Of course, a good method of Kevin type wiring method is to reduce the SPD lead, if the conditions used should be used as far as possible, but not all places can be used this way, it is the biggest flaw in the distribution system due to the large capacity of bus line diameter large (or using copper), and SPD the terminal capacity is limited, unable to make this connection. In addition, because the power line first to SPD, then from SPD to distribution equipment or electrical equipment, inevitably increase two joints, if not handled properly, such as poor contact, contact oxidation and loose contact, resulting in heating current is high, can cause power outages, can also cause severe burns serious accidents, there is precedent for this lesson. Therefore, Kevin type wiring is not a panacea, but also need to be selectively used according to the actual situation.
          Here we list a common parallel connection mode and the use of Kevin connection mode in the specific application of the base station environment:
          Not handled properly, such as poor contact, contact oxidation and loose contact, resulting in heating current is high, can cause power outages, can also cause severe burns and other accidents, there is precedent for this lesson. Therefore, Kevin type wiring is not a panacea, but also need to be selectively used according to the actual situation.
          Here we list a common parallel connection mode and the use of Kevin connection mode in the specific application of the base station environment:
          Above is an example of the use of Kevin type wiring, so that there are several advantages of the installation:
          5 distribution system and equipment grounding wire without change, the project is small.
          6 lightning protection box in the front end can protect all the load behind, the most comprehensive protection.
          The 7 lightning protection box is installed beside the total grounding bus wire, the shortest, the minimum residual pressure, lightning inflow channel is the most reasonable, effective protection
          Best fruit.
          8 grounding of all equipment are connected to the main earthing busbar, a reference potential, without risk potential counterattack. Of course, the example is the ideal case, if the power wire diameter is too large, the distribution line is not long enough, outdoor circuit breakers, lightning protection box without proper installation space, the implementation will hinder the Kevin connection.
          We should grasp the overall situation, reasonable design, follow the standard, flexible application, careful construction, strictly regulate engineering. Kevin type wiring in the project to be used, in order to get the best protection effect, but ignore the specific application environment, blindly emphasize the use of Kevin type wiring, but also impractical.
