Problems solved by technology
 figure 1 It is the case of adding mesh wires to cement poles, where 1 is the original single ground wire, 2 is the (connected) round hoop, and 3 is the bent metal round bar (that is, adding multiple metal strip ground wires).
 A multi-metal overvoltage and overcurrent releaser for lightning strikes. The hoop 2 is composed of two semicircular hoops with the same shape. Each semicircular hoop has an ear plate for bolt connection at both ends, and each semicircular hoop is uniformly welded with A plurality of crimping pieces 4, the crimping piece 4 punched by metal plate is composed of an inverted U-shaped piece and left and right ear pieces, and each crimping piece 4 is inserted with a bent metal round bar 3 , and the curved metal round bar 3 and the left and right gaps of the corresponding crimping piece 4 are respectively pressed with arc-shaped wedges 5 for fixing ( figure 2 Each bent metal round bar is inserted into two crimping pieces and fixed, that is, mu...
