直埋電纜敷設有哪些要求

直埋纜線敷設有什么樣的規定？（1）挖方的溝底是柔軟的土壤，若是石子或硬塑拉積要鋪100mm厚的軟土或砂層。纜線周的土壤如包含的腐蝕纜線五金包皮，應清空和換土，埋深應不不大于0.7m，爬過水稻田時需要不不大于1m。在對接工程物、與地底工程物交差及避開地底工程物處，可淺埋，但應體現了呵護錯施，纜線應埋于凍層壤接下來，當受能力因為限制時，應體現了放到纜線因為板材損害的錯施。（2）電線敷設后，表面要鋪100mm厚的軟土或沙子，再扣上水泥現澆混泥土土土保護性措施板，覆蓋率凈寬應小于電線外側外各50mm，或用磚充當水泥現澆混泥土土土保護性措施板。

（3）在(zai)(zai)期間(jian)接(jie)線(xian)(xian)(xian)頭盒(he)內面要有鑄件或混疑土愛(ai)護(hu)(hu)盒(he)。（4）插頭以下(xia)應(ying)(ying)(ying)墊以水(shui)泥商混土框架板，大小要張(zhang)開插頭保(bao)障盒(he)兩端(duan)600?700mm，拖(tuo)鏈電(dian)(dian)(dian)(dian)纜(lan)自(zi)土溝獲(huo)批(pi)所(suo)謂(wei)的(de)隧道、人孔和(he)(he)建筑施工(gong)物時，要穿在(zai)(zai)管(guan)(guan)(guan)內，并將出口堵死，以免漏水(shui)。（5）數據線(xian)(xian)(xian)相(xiang)互雙向(xiang)(xiang)，和(he)(he)非供熱公(gong)司管(guan)(guan)(guan)和(he)(he)熱力管(guan)(guan)(guan)道雙向(xiang)(xiang)，穿線(xian)(xian)(xian)二級公(gong)路和(he)(he)墻邊時，必須穿在(zai)(zai)自(zi)我(wo)保(bao)護(hu)(hu)管(guan)(guan)(guan)內，自(zi)我(wo)保(bao)護(hu)(hu)管(guan)(guan)(guan)的(de)長度超(chao)(chao)額雙向(xiang)(xiang)點(dian)1m，雙向(xiang)(xiang)凈(jing)距不(bu)(bu)會不(bu)(bu)低(di)于250mm，自(zi)我(wo)保(bao)護(hu)(hu)管(guan)(guan)(guan)內徑不(bu)(bu)會不(bu)(bu)低(di)于數據線(xian)(xian)(xian)外徑的(de)1.5倍。（6）直(zhi)埋(mai)拖(tuo)鏈電(dian)(dian)(dian)(dian)覽(lan)(lan)似的(de)在(zai)(zai)使用(yong)鎧(kai)裝(zhuang)拖(tuo)鏈電(dian)(dian)(dian)(dian)覽(lan)(lan)。在(zai)(zai)鎧(kai)裝(zhuang)拖(tuo)鏈電(dian)(dian)(dian)(dian)覽(lan)(lan)的(de)金屬件外皮兩端(duan)要不(bu)(bu)靠譜接(jie)地極系(xi)統，接(jie)地極系(xi)統電(dian)(dian)(dian)(dian)阻功率不(bu)(bu)應(ying)(ying)(ying)不(bu)(bu)超(chao)(chao)10Ω。（7）直(zhi)埋(mai)數據線(xian)(xian)(xian)在(zai)(zai)條直(zhi)線(xian)(xian)(xian)段間(jian)隔50?100m處(chu)，數據線(xian)(xian)(xian)連接(jie)管(guan)(guan)(guan)處(chu)、轉彎(wan)處(chu)、入駐(zhu)建筑材(cai)料物等處(chu)，應(ying)(ying)(ying)設置特別的(de)多方面圖標(biao)或標(biao)樁。（8）高壓電(dian)(dian)(dian)(dian)覽(lan)(lan)與另一個途徑、道路上、建筑裝(zhuang)修物等中間(jian)相(xiang)平行線(xian)(xian)(xian)和(he)(he)交叉點(dian)時的(de)小凈(jing)距，應(ying)(ying)(ying)適合規(gui)經營范指(zhi)定。禁止酒后開車將高壓電(dian)(dian)(dian)(dian)覽(lan)(lan)相(xiang)平行線(xian)(xian)(xian)敷設于途徑的(de)頂端(duan)或以下(xia)。
