What are the key points of grounding of cable bridge?

1.架體系應(yīng)具有牢靠的電氣銜接并接地（只對(duì)金屬橋架）。

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

2.當(dāng)答應(yīng)使用橋架體系構(gòu)成接地干線回路時(shí)應(yīng)契合下列要求。橋架端部之間銜接電阻應(yīng)不大于0.00033歐姆，接地孔應(yīng)鏟除絕緣涂層。在1KV及以下中性點(diǎn)直接接地體系中，受電設(shè)備的接地與體系中性線接地相連。裝有處動(dòng)切斷供電裝軒時(shí)，橋架的級(jí)長方向金屬橫截面積應(yīng)不小于規(guī)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(shè)接地干線時(shí)，每段（包含非直線段）橋架應(yīng)至少有一點(diǎn)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(guān)于振蕩場(chǎng)所，在接地部位的銜接處應(yīng)設(shè)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(yù)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(dāng)?shù)鼐陀袠蚣堋蚣艿氖褂梅秶m當(dāng)廣泛，各行各業(yè)都有涉足，大多數(shù)使用在數(shù)據(jù)中心、辦公室、互聯(lián)網(wǎng)效勞供貨商、醫(yī)院、校園/大學(xué)、機(jī)場(chǎng)及工廠等，非常是數(shù)據(jù)中心和IT機(jī)房商場(chǎng)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(shì)

Developing trend

社會(huì)在進(jìn)步，產(chǎn)品在更新。橋架產(chǎn)品亦有更大的開展空間。節(jié)能環(huán)保是時(shí)下各行各業(yè)的干流，如果能生產(chǎn)出節(jié)能、漂亮、便利、時(shí)尚的橋架產(chǎn)品，立異快捷的數(shù)據(jù)纜辦理體系，為各類電纜和裝置人員提供大安全維護(hù)，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.
