What are the key points of grounding of cable bridge?

1.架体系应具有牢靠的电气衔接并接地（只对金属桥架）。

The 1. systems should have reliable electrical connection and grounding (only metal bridge).

2.当答应使用桥架体系构成接地干线回路时应契合下列要求。桥架端部之间衔接电阻应不大于0.00033欧姆，接地孔应铲除绝缘涂层。在1KV及以下中性点直接接地体系中，受电设备的接地与体系中性线接地相连。装有处动切断供电装轩时，桥架的级长方向金属横截面积应不小于规定值。

2. when it is agreed to use the bridge system to form the grounding trunk circuit, it should meet the following requirements. The resistance between the ends of the bridge should not be greater than 0.00033 ohms, and the insulating holes should be removed from the grounding holes. In the neutral point direct grounding system below 1KV, the grounding of the receiving equipment is connected with the neutral line grounding of the system. When the power supply is cut off, the cross section area of the length of the bridge should not be less than the specified value.

3.沿桥架全长另敷设接地干线时，每段（包含非直线段）桥架应少有一点与接地干线牢靠衔接。

3. When laying another grounding trunk along the full length of the bridge, each section (including non-linear section) of the bridge should have at least one point firmly connected with the grounding trunk.

4.关于振荡场所，在接地部位的衔接处应设备弹簧圈。

4. for oscillating sites, equipment springs should be installed at the junction of grounding parts.

装置使用

Device use

电缆桥架的装置首要分几种：沿顶板装置、沿墙水平缓垂直装置、沿竖井装置、沿地上装置、沿电缆沟及管道支架装置等。装置所用支（吊）架可选用制品或克己。支（吊）架的固定方法首要有预埋铁件上焊接，膨胀螺栓固定等。

There are mainly several kinds of cable bridge bracket devices: along the roof device, along the wall horizontal and vertical device, along the shaft device, along the ground device, along the cable trench and pipeline bracket device. The support used for the device can be selected by products or self control. The fixing method of the bracket is mainly on the embedded iron parts, the expansion bolt fixing and so on.

有线缆的当地就有桥架。桥架的使用范围适当广泛，各行各业都有涉足，大多数使用在数据中心、办公室、互联网效劳供货商、医院、校园/大学、机场及工厂等，特别是数据中心和IT机房是未来桥架使用非常大的一块。

Where there are cables, there are bridges. Bridges are widely used in all walks of life. Most of them are used in data centers, offices, Internet service providers, hospitals, campuses/universities, airports and factories, especially in data centers and IT computer room shopping malls.

开展趋势

Developing trend

社会在进步，产品在更新。桥架产品亦有更大的开展空间。是时下各行各业的干流，如果能生产出、漂亮、便利、时尚的桥架产品，立异的数据缆办理体系，为各类电缆和装置人员提供大维护，才是重要的。

Society is improving and products are upgrading. Bridge products also have greater room for development. Energy-saving and environmental protection are the mainstream of all walks of life at present. If we can produce energy-saving, beautiful, convenient and fashionable bridge products, innovative and efficient data cable management system, and provide maximum safety maintenance for all kinds of cable and installation personnel, it is the most important.
