Cable tray by tray or a straight run of ladder, curved, components and bracket timbering (arm), hanger, etc with contact support the full name of the rigid structure of the cable system. It is raised with the pipe rack placed cable trough type metal frame. Cable tray factory have all varieties, wide application, intensity big, light structure, low cost, simple construction, flexible wiring, installation standards, appearance, etc.

　　為了規(guī)范電纜橋架配件和電纜橋架市場(chǎng)，相關(guān)部門公布了橋架配件的標(biāo)準(zhǔn)定義。電纜橋架廠家提醒諸位，電纜橋架的購(gòu)買也是極其重要的，配件的選擇需要、抗壓，能滿足施工需要。常用的電纜橋架有三通、彎頭、異徑、螺絲、扣鎖、托臂、吊桿、橫擔(dān)、連接片、接地線等等。

　　In order to standardize the market for cable tray accessories and cable tray, related department released the standard definition of bridge accessories. Cable tray factory to remind you, purchase of cable tray is extremely important, the choice of accessories need to high quality, compressive strength, can meet the needs of the construction. Commonly used cable bridge has three links, elbow, reducer, screw, padlocks, bracket, derrick, cross arm, connecting pieces, ground wire, and so on.

　　常用的橋架附件有電纜終端接線盒、電纜中間接線盒、連接管及接線端子、鋼板接線槽等等。對(duì)于振動(dòng)場(chǎng)所，在接地部位的連接處應(yīng)裝置彈簧圈。橋架系統(tǒng)應(yīng)具有可靠的電氣連接并接地。當(dāng)允許利用橋架系統(tǒng)構(gòu)成接地干線回路時(shí)應(yīng)符合一下要求：

　　Commonly used bridge accessories have cable terminal connector, cable junction box, connecting the middle tube and terminal blocks, wiring groove of the steel plate and so on. For vibration place, in the joint of ground parts should be spring coil. Bridge system should have reliable electrical connection and ground. When allowed to use bridge system grounding should conform to the requirements of main loop:

　　1、橋架端部之間連接電阻不能大于0.00033歐姆，接地孔應(yīng)絕緣涂層。

　　1, the connection between the bridge end resistance is not greater than 0.00033 ohms, grounding insulation coating shall be removed.

　　2、在1kv及以下中性點(diǎn)直接接地系統(tǒng)中，受電設(shè)備的接地與系統(tǒng)中性線接地相連。

　　2, in the neutral point grounding system directly 1 kv and below, from electrical equipment grounding connected to the neutral grounding system.
