The cable tray is suitable for laying power cable and control cable indoors and outdoors in industrial and mining enterprises, and also for indoor and outdoor erection in telecommunication, radio and television departments.

為了規(guī)范電纜橋架配件和電纜橋架市場，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 cable tray accessories and cable tray Market, relevant departments published the standard definition of cable tray accessories. Cable tray manufacturers remind you that the purchase of cable tray is also extremely important. The selection of accessories needs high quality and compression resistance to meet the construction needs. The commonly used cable trays include tee, elbow, reducer, screw, lock, bracket, suspender, cross arm, connecting piece, grounding wire, etc.

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。對于振動(dòng)場所，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：

Common bridge accessories include cable terminal box, cable intermediate box, connecting pipe and terminal, steel plate wiring slot, etc. For vibration place, spring coil should be installed at the connection of grounding part. The bridge system shall have reliable electrical connection and grounding. The following requirements shall be met when the main line grounding system is formed:

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 resistance between bridge ends shall not be greater than 0.00033 ohm, and the insulation coating shall be removed from the grounding hole.

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 system of 1kV and below neutral point direct grounding, the grounding of the receiving equipment is connected with the neutral line of the system.

以上就是小編講解的相關(guān)內(nèi)容，希望可以幫助到您！
