5.4不同防火区的桥架,应按设计要求,采取防火、隔离措施;
Fireproofandisolationmeasuresshallbetakenforthecabletrayslaidinsideverticalshaftoracrossdifferentfireproofareas;
5.5对于SPCII厂房内部所有600mm宽的桥架,必须在桥架内敷设一根95mm2的裸铜绞线作为接地线,然后分别与SPCI主桥架内95mm2的裸铜绞线相连接,对于主管廊上的桥架,应在最上层电缆桥架内敷设一根95mm2的裸铜绞线作为接地线,并且分别与全厂接地网连接。
电气桥架必须有良好的电气通路,桥架两端并且每隔30m做一次接地线;

7.2.1根据桥架施工图,合理安排桥架支架安装位置,标注好桥架支架安装的具体位置,计算出每根支架的尺寸,在事先选好的C型钢材上标出相应的位置;
标出后统一拿到预制场地加工,严禁在现场加工支架.对于装纳电缆容量大的桥架应选用背靠背叠在一处的C型钢支架,增强支架强度;
