電纜橋架布線的標準

作者: 來源: 日期:2022/7/2 9:24:53

電纜橋架安裝一般是由水電師傅落實的,但很多水電安裝師傅都沒有經過專業培訓,因此工地施工現場存在差別較大,今天我們就來學習電纜橋架布線的標準:

一、電纜橋架在室內布線時,其電纜不得有黃麻或其它易延燃材料的外保護層。云南橋架.jpg

二、電纜橋架水平安裝時,直接荷載曲線選擇最佳跨度支撐,一般跨度為1.5m-3m,垂直敷設時,固定點之間的距離不應大于2m。

三、電纜橋架布線在腐蝕性或潮濕場合進行時,應根據不同的腐蝕物質采取相應的保護措施,并可選擇塑料套保護電纜。

四、多組電纜橋架安裝在同一高度時,各相鄰電纜橋架可考慮維護距離。

五、電纜橋架上可進行無間距敷設電纜,電纜在橋架內橫斷面的填充率:電力電纜不能大于40%,控制電纜不能大于50%。昆明橋架廠家.png

六、電纜橋架(托盤)水平安裝的距地高度一般不小于2.5m,垂直安裝時距地1.8m除敷設電氣專用房間(如電氣豎井、技術層、電室)外,下部應加金屬蓋板保護。

七、電纜橋架不得安裝在腐蝕性氣體管道和熱管道上方和腐蝕性液體管道下方,必須采取防腐保溫措施。

以下不同電壓、不同用途的電纜不適合敷設在同一層橋上。

九、電纜橋架與各種管道平行或交叉時,其最小凈距應符合表DQ4-1的規定。

以上是電纜橋架布線標準表的介紹,在進行電纜橋架布線時可以參考。

Cable tray installation is generally implemented by the hydropower master, but many hydropower installation masters have not been professional training, so there are big differences in the construction site, today we will learn the cable tray wiring standard:

First, when the cable bridge is wiring indoors, the cable shall not have the outer protective layer of jute or other inflammable materials.

Ii. When the cable bridge is installed horizontally, the direct load curve chooses the best span support, the general span is 1.5m to 3m, and the distance between fixed points should not be greater than 2m when laying vertically.

Three, cable tray wiring in corrosive or wet occasions, should take corresponding protection measures according to different corrosive substances, and can choose plastic protection cable.

Four, when multiple groups of cable Bridges are installed at the same height, the maintenance distance of the adjacent cable Bridges can be considered.

Five, cable bridge can be laid without spacing cable, cable in the bridge cross-sectional filling rate: power cable can not be more than 40%, control cable can not be more than 50%.

Six, cable tray (tray) horizontal installation distance from the ground height is generally not less than 2.5m, vertical installation distance from the ground 1.8m in addition to laying electrical special room (such as electrical shaft, technical layer, electricity room), the lower part of the metal cover plate protection.

7. Cable tray shall not be installed above corrosive gas pipeline and hot pipeline and below corrosive liquid pipeline, and anti-corrosion and heat preservation measures must be taken.

The following cables with different voltages and purposes are not suitable for laying on the same bridge.

Nine. When the cable tray is parallel or crossed with various pipelines, the minimum net distance shall conform to the provisions of Table DQ4-1.

The above is the introduction of cable bridge wiring standard table, which can be referred to when cable bridge wiring.
