电缆桥架适合于何种场合?

电缆桥架适用于一般工矿企业室内外架空敷设电力电缆、控制电缆,亦可用于电信、广播电视等部门在室内外架设。
The cable bridge is suitable for laying power cables and control cables in general industrial and mining enterprises indoor and outdoor. It can also be used for Telecom, radio and television departments to set up indoor and outdoor.
选择电缆桥架根据电缆荷载及桥架安装处的环境,以电缆桥架的载荷曲线为依据,来确定电缆桥架的类型和规格及立柱的间距、托臂的长度、电缆桥架的层次,立柱的长度等。
According to the cable load and the environment where the cable tray is installed, and based on the load curve of the cable tray, the type and specification of the cable tray, the spacing of the column, the length of the bracket arm, the level of the cable bridge and the length of the column are determined.
当电缆桥架的固定方式采用悬挂式且托臂为单侧多层式安装时,为了立注受力平衡,应选用对材载荷方式,敷设电缆桥架。
When the cable tray is suspended and the bracket is installed in one side and multi-layer, in order to balance the vertical injection force, the material loading mode should be selected to lay the cable bridge.
大跨距敷设电缆,可选用大跨距电缆桥架。
Long span cable tray can be selected for long span cable laying.
电缆桥架在穿越易受外来机械损伤的地区和日晒地区,应选用防护盖板。当电缆槽或桁架式梯架需转变分支时,可采用各种弯通连接。
The protective cover plate shall be selected for cable tray crossing the area vulnerable to external mechanical damage and sun exposure. When the cable tray or truss ladder needs to change branches, various elbow connections can be used.
选择电缆桥架的支撑间距应小于允许支撑跨距。宽度应留有一定的备用空位,以便以后增添电缆用。
The support spacing of cable tray shall be less than the allowable support span. A certain spare space should be reserved for the width, so as to add the cable in the future.
电缆桥架的防腐措施为:塑料喷涂、镀锌钝化、电镀锌(适用于轻防腐地区)热浸镀锌、热喷锌(适用于重防腐地区)镀锌镍合金等。热浸镀锌电缆桥架用料厚度需增加0.5mm以上。
The anti-corrosion measures of cable tray are as follows: plastic spraying, galvanizing and passivation, electro galvanizing (applicable to light anti-corrosion areas) hot-dip galvanizing, hot-dip galvanizing (applicable to heavy-duty areas) zinc nickel alloy, etc. The thickness of hot-dip galvanized cable tray should be increased by more than 0.5mm.
