一、電(dian)(dian)(dian)(dian)纜(lan)按(an)應用(yong)分(fen)(fen)：（1）電(dian)(dian)(dian)(dian)力(li)系統(tong)：架空裸(luo)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)、匯流排(pai)（母線(xian)(xian)(xian)）、電(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)纜(lan)（塑料線(xian)(xian)(xian)纜(lan)、油紙電(dian)(dian)(dian)(dian)纜(lan)（基本被塑料電(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)纜(lan)代替(ti)）、橡套線(xian)(xian)(xian)纜(lan)、架空絕緣(yuan)電(dian)(dian)(dian)(dian)纜(lan)）、分(fen)(fen)支電(dian)(dian)(dian)(dian)纜(lan)（取代部(bu)分(fen)(fen)母線(xian)(xian)(xian)）、電(dian)(dian)(dian)(dian)磁線(xian)(xian)(xian)以(yi)及(ji)電(dian)(dian)(dian)(dian)氣設備(bei)用(yong)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)等。（2）信息傳輸(shu)系統(tong)：市話電(dian)(dian)(dian)(dian)纜(lan)、電(dian)(dian)(dian)(dian)視電(dian)(dian)(dian)(dian)纜(lan)、...

1、規范施工在敷(fu)設(she)電(dian)(dian)(dian)纜(lan)時，施工人員(yuan)必須保證施工質量，規范施工。在施工時要防(fang)止牽引(yin)力過大、彎(wan)曲過度、填土不實(shi)、埋設(she)深(shen)度不夠等(deng)造成的，機械(xie)性損(sun)傷。電(dian)(dian)(dian)纜(lan)的中間接頭和終端頭統(tong)稱為(wei)電(dian)(dian)(dian)纜(lan)頭。電(dian)(dian)(dian)纜(lan)頭是影(ying)響電(dian)(dian)(dian)纜(lan)絕緣性能的關鍵部(bu)位，最容易成為(wei)引(yin)火源。因此(ci)，電(dian)(dian)(dian)...

電(dian)力電(dian)纜是在電(dian)力系統中(zhong)(zhong)傳輸或分(fen)配大功率電(dian)能用的電(dian)纜。隨著世界范圍內(nei)的石油(you)化學工(gong)業大發展，塑料(liao)絕緣(yuan)電(dian)力電(dian)纜由于其制造工(gong)藝簡(jian)單，施工(gong)、維護便捷(jie)，成為低壓電(dian)力電(dian)纜中(zhong)(zhong)的重要品種。然而在塑料(liao)絕緣(yuan)擠制過(guo)程(cheng)中(zhong)(zhong)不(bu)免(mian)會產生碰傷(shang)、刮傷(shang)、壓傷(shang)、擊穿(chuan)等缺(que)陷(xian)點，為了(le)...

電(dian)力(li)電(dian)纜的(de)絕緣層(ceng)是(shi)由紙、油(you)、麻、橡膠、塑料、瀝青等各種可燃物質組成，因此，電(dian)纜具有起(qi)火爆炸(zha)的(de)可能性。導致(zhi)電(dian)纜起(qi)火爆炸(zha)的(de)原因是(shi)：（1）絕緣損(sun)壞引(yin)起(qi)短路故障。電(dian)力(li)電(dian)纜的(de)保護鉛皮在(zai)敷(fu)設時被損(sun)壞或在(zai)運行中(zhong)電(dian)纜絕緣受(shou)機(ji)械損(sun)傷，引(yin)起(qi)電(dian)纜相間或鉛皮間的(de)絕...

在電(dian)力(li)線(xian)路中，電(dian)纜所占(zhan)比重正(zheng)逐漸增(zeng)加。電(dian)力(li)電(dian)纜是在電(dian)力(li)系統的主干線(xian)路中用以(yi)傳輸和分配大功率電(dian)能的電(dian)纜產(chan)品，包(bao)括1-500KV以(yi)及以(yi)上各種電(dian)壓等級(ji)，各種絕緣的電(dian)力(li)電(dian)纜。電(dian)力(li)電(dian)纜的基(ji)本結構由線(xian)芯(xin)（導體）、絕緣層(ceng)、屏(ping)蔽層(ceng)和保護(hu)層(ceng)四(si)部分組成(cheng)。一、線(xian)...

在電(dian)(dian)(dian)(dian)力(li)線路中，電(dian)(dian)(dian)(dian)纜(lan)所占比重正(zheng)逐漸增加。電(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)纜(lan)是在電(dian)(dian)(dian)(dian)力(li)系統的主干線路中用以傳輸和分配(pei)大功率電(dian)(dian)(dian)(dian)能的電(dian)(dian)(dian)(dian)纜(lan)產品，包括(kuo)1-500KV以及以上(shang)各(ge)種(zhong)電(dian)(dian)(dian)(dian)壓等級(ji)，各(ge)種(zhong)絕緣的電(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)纜(lan)。一(yi)、按(an)電(dian)(dian)(dian)(dian)壓等級(ji)分按(an)電(dian)(dian)(dian)(dian)壓等級(ji)可(ke)分為中、低壓電(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)纜(lan)（35千伏及以下）、高(gao)壓電(dian)(dian)(dian)(dian)...
