电缆桥架工程施工要求

昆明桥架厂家在使用1KV绝缘穿刺线夹时，工程施工的具体要求是什么？现实中，在电缆桥架安装中，安装人员需要注意很多方面，尤其是在后期需要分支和铺设桥架电缆时，对桥架电缆的铺设有一系列的硬要求和标准。

电缆桥架的敷设路径和标高应与其他专业管道协调，布局合理，施工维护方便。电缆桥架与各专业管道之间的距离 具体参数应达到，以便于希卡姆绝缘穿刺线夹在后期分支。如果在同一标高处交叉，必要时可以上下翻转，以便合理避免。桥梁离地高度应尽可能提高，以留出足够的空间。铺设路径遇到结构梁时，应向下翻转，梁底不小于20cm。

电缆绑扎规定：多芯电缆水平敷设，直线间距不大于10m；垂直敷设间距不大于11.5m；单芯电缆间距不大于1m。这样做的好处是，在后期使用希卡姆绝缘穿刺线夹时，桥梁电缆分支不需要大规模移动电缆。主电路和备用电路的电缆，一般电路和应急电路电缆应分别敷设在不同的桥架上。当不能分开时，应在桥架上设置防火隔断，或使用防火希卡姆绝缘穿刺线夹。当电缆桥穿过结构伸缩缝或沉降缝时，应留出20个~30cm长度余量，并采用伸缩连接方式。在有驾驶车间的车间内，可选择跨柱安装电缆桥架路径或屋架下弦安装，缆桥架在驾驶起重范围内可靠接地。

Cable bundling requirements: multi-core cables are laid horizontally and the linear spacing is not greater than 10m. Vertical laying spacing is not more than 11.5m; The distance between single-core cables is less than 1m. The advantage of this is that the bridge cable branch does not require mass cable movement when hickam insulated puncture clips are used later. Cables of main circuit and spare circuit, general circuit and emergency circuit should be laid on different Bridges. When it is not possible to separate, a fireproof partition shall be installed on the bridge, or a fireproof Hickam insulated piercing clip shall be used. When the cable bridge passes through the expansion joint or settlement joint of the structure, 20 ~30cm length allowance should be set aside, and the expansion connection mode should be adopted. In the workshop with driving workshop, you can choose to install cable tray path or cable tray string installation, cable bridge in the driving lifting range of reliable grounding.
