描述

金屬線槽布線

(1)金屬線槽布線一般適用于正常環(huán)境的室內(nèi)干燥和不易受機(jī)械損傷的場(chǎng)所明敷，但對(duì)金屬線槽有嚴(yán)重腐蝕的場(chǎng)所不應(yīng)采用。

(2)同一回路的所有相線和中性線，應(yīng)敷設(shè)在同一金屬線槽內(nèi)。同一路徑無(wú)防干擾要求的線路，可敷設(shè)于同一金屬線槽內(nèi)。線槽內(nèi)電線或電纜的總截面(包括外護(hù)層)不應(yīng)超過(guò)線槽內(nèi)截面的20%，載流導(dǎo)線不宜超過(guò)30根。控制、信號(hào)或與其相類(lèi)似的線路，電線或電纜的總截面不應(yīng)超過(guò)線槽內(nèi)截面的50%，電線或電纜根數(shù)不限。

(3)金屬線槽垂直或傾斜安裝時(shí)，應(yīng)采取措施防止電線或電纜在線槽內(nèi)移動(dòng)。

(4)由金屬線槽引出的線路，可采用金屬管、硬質(zhì)塑料管、半硬塑料管、金屬軟管或電纜等布線方式。電線或電纜在引出部分不得遭受損傷。

(5)線槽應(yīng)平整、無(wú)扭曲變形，內(nèi)壁應(yīng)光滑、無(wú)毛刺。

(6)金屬線槽應(yīng)可靠接地或接零，但不應(yīng)作為設(shè)備的接地導(dǎo)體。
