直埋電纜敷設有哪些要求

直埋電線敷設有什么樣標準？（1）挖溝的溝底是比較松軟的持力層，倘若是卵石或孔狀異物要鋪100mm厚的軟土或砂層。電線有的小石子如含耐腐蝕電線塑料包皮，應清掉和換土，埋深應不低于0.7m，空間穿越田地該不低于1m。在引進古筑物、與地窖古筑物穿插及跳過地窖古筑物處，可淺埋，但應體現了保護保護，電線應埋于凍持力層如下，當受生活條件規定時，應體現了阻止電線備受破損的保護。（2）低壓電纜線敷設后，以上要鋪100mm厚的軟土或泥沙，再蓋緊水泥水泥墊塊土護理板，涵蓋尺寸應少于低壓電纜線下邊范圍內各50mm，或用磚帶替水泥水泥墊塊土護理板。

（3）里面(mian)線(xian)(xian)接(jie)頭盒(he)里邊要(yao)有鐵質或(huo)混(hun)泥土土保(bao)養(yang)盒(he)。（4）連(lian)接(jie)管(guan)(guan)內間應(ying)(ying)墊(dian)以混(hun)疑(yi)土基礎性板(ban)，直(zhi)(zhi)徑要(yao)伸長連(lian)接(jie)管(guan)(guan)保(bao)養(yang)盒(he)兩端600?700mm，拖鏈電(dian)纜自土溝招引(yin)隧道工(gong)(gong)程、人孔和(he)建筑(zhu)材料(liao)物(wu)時，要(yao)穿(chuan)(chuan)(chuan)(chuan)(chuan)在(zai)(zai)(zai)管(guan)(guan)內，并將管(guan)(guan)道堵塞(sai)了，處(chu)(chu)(chu)理滲(shen)漏。（5）電(dian)攬(lan)(lan)線(xian)(xian)雙(shuang)方穿(chuan)(chuan)(chuan)(chuan)(chuan)插(cha)，與其熱能(neng)管(guan)(guan)和(he)管(guan)(guan)材穿(chuan)(chuan)(chuan)(chuan)(chuan)插(cha)，爬過(guo)高速公路和(he)水(shui)泥墻時，都是要(yao)穿(chuan)(chuan)(chuan)(chuan)(chuan)在(zai)(zai)(zai)愛護(hu)分液漏斗，愛護(hu)管(guan)(guan)總長度低于(yu)穿(chuan)(chuan)(chuan)(chuan)(chuan)插(cha)點1m，穿(chuan)(chuan)(chuan)(chuan)(chuan)插(cha)凈(jing)距(ju)不會低于(yu)250mm，愛護(hu)管(guan)(guan)內徑不會低于(yu)電(dian)攬(lan)(lan)線(xian)(xian)外(wai)徑的1.5倍。（6）直(zhi)(zhi)埋高壓拖鏈電(dian)攬(lan)(lan)般運用(yong)鎧裝高壓拖鏈電(dian)攬(lan)(lan)。在(zai)(zai)(zai)鎧裝高壓拖鏈電(dian)攬(lan)(lan)的鋁合金(jin)外(wai)皮兩端要(yao)穩定(ding)可(ke)靠保(bao)護(hu)與地面(mian)，保(bao)護(hu)與地面(mian)電(dian)阻功率(lv)不宜(yi)以上10Ω。（7）直(zhi)(zhi)埋電(dian)覽在(zai)(zai)(zai)條直(zhi)(zhi)線(xian)(xian)段每過(guo)50?100m處(chu)(chu)(chu)，電(dian)覽連(lian)接(jie)管(guan)(guan)處(chu)(chu)(chu)、轉(zhuan)彎處(chu)(chu)(chu)、走(zou)進建筑(zhu)材料(liao)物(wu)等(deng)處(chu)(chu)(chu)，應(ying)(ying)放置看(kan)不出的東南方向標(biao)志的意思或(huo)標(biao)樁。（8）纜線(xian)(xian)與某個管(guan)(guan)路、道路施工(gong)(gong)、工(gong)(gong)程建筑(zhu)等(deng)中(zhong)水(shui)平線(xian)(xian)和(he)交疊時的小凈(jing)距(ju)，應(ying)(ying)合適標(biao)準規范(fan)標(biao)準。禁上將纜線(xian)(xian)水(shui)平線(xian)(xian)敷設于(yu)管(guan)(guan)路的右上角或(huo)左(zuo)上角。
