What are the key points of grounding of cable bridge?

1.架體系應具有牢靠的電氣銜接并接地（只對金屬橋架）。

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

2.當答應使用橋架體系構成接地干線回路時應契合下列要求。橋架端部之間銜接電阻應不大于0.00033歐姆，接地孔應鏟除絕緣涂層。在1KV及以下中性點直接接地體系中，受電設備的接地與體系中性線接地相連。裝有處動切斷供電裝軒時，橋架的級長方向金屬橫截面積應不小于規定值。

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.沿橋架全長另敷設接地干線時，每段（包含非直線段）橋架應少有一點與接地干線牢靠銜接。

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.關于振蕩場所，在接地部位的銜接處應設備彈簧圈。

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

裝置使用

Device use

電纜橋架的裝置首要分幾種：沿頂板裝置、沿墻水平緩垂直裝置、沿豎井裝置、沿地上裝置、沿電纜溝及管道支架裝置等。裝置所用支（吊）架可選用制品或克己。支（吊）架的固定方法首要有預埋鐵件上焊接，膨脹螺栓固定等。

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.

有線纜的當地就有橋架。橋架的使用范圍適當廣泛，各行各業都有涉足，大多數使用在數據中心、辦公室、互聯網效勞供貨商、醫院、校園/大學、機場及工廠等，特別是數據中心和IT機房是未來橋架使用非常大的一塊。

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.

開展趨勢

Developing trend

社會在進步，產品在更新。橋架產品亦有更大的開展空間。是時下各行各業的干流，如果能生產出、漂亮、便利、時尚的橋架產品，立異的數據纜辦理體系，為各類電纜和裝置人員提供大維護，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.
