▲ 桥架跨接线连接要注意：用抓垫、平垫或把喷塑桥架的漆刮掉再用平垫、弹簧垫压紧。镀锌电缆桥架间连接板的两端不跨接接地线，但连接板两端不少于2个有防松螺帽或防松垫圈的连接固定螺栓（强标） 。至于支架的接地，就是把支架与桥架连接处固定刮漆就可以（或是抓垫）。接地线最小截面不小于4平方米。
Attention should be paid to bridge spanning connection: scrape off the paint of spray-moulded bridge frame with grasping pad, flat pad or spring pad. The two ends of the connecting plate between galvanized cable bridges do not cross the ground wire, but there are no less than two connecting bolts (strong standard) with anti-loosening nuts or washers at both ends of the connecting plate. As for the grounding of the bracket, it is possible to fix the scraping paint at the connection between the bracket and the bridge. The minimum section of grounding wire is not less than 4 square meters.
▲ 金属电缆桥架及其支架全长应不少于2处与接地（PE）或接零（PEN）干线相连接；
_The full length of the metal cable bridge and its support shall be not less than 2 places connected with the main line of grounding (PE) or zero connection (PEN);
▲ 跨接线压线处细部做法：
_Detailed practices of cross-connection line pressing:
注意垫片及顺序及螺栓外露的长度及接地标识、螺栓的位置；不能用连接螺栓固定跨接线。
Pay attention to the gasket and sequence, the length of bolt exposed, the grounding mark and the position of bolt; the connecting bolt can not be used to fix the cross connection.
