珠(zhu)江低煙無鹵電纜 WDZ-YJY
YJY電纜圖
手冊(ce)往往只提供了(le)YJV電(dian)(dian)(dian)(dian)纜(lan)(lan)和BV電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)(xian)的(de)(de)載(zai)(zai)(zai)(zai)流(liu)(liu)(liu)量(liang)(liang)(liang)(liang)，YJY電(dian)(dian)(dian)(dian)纜(lan)(lan)和BYJ電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)(xian)的(de)(de)載(zai)(zai)(zai)(zai)流(liu)(liu)(liu)量(liang)(liang)(liang)(liang)是(shi)(shi)(shi)(shi)(shi)多(duo)少，怎樣查？ 我(wo)說，YJY電(dian)(dian)(dian)(dian)纜(lan)(lan)和BYJ的(de)(de)絕(jue)緣(yuan)(yuan)層與(yu)YJV是(shi)(shi)(shi)(shi)(shi)相同(tong)(tong)的(de)(de)，其(qi)載(zai)(zai)(zai)(zai)流(liu)(liu)(liu)量(liang)(liang)(liang)(liang)差不多(duo)，比VV電(dian)(dian)(dian)(dian)纜(lan)(lan)、BV導(dao)線(xian)(xian)(xian)(xian)(xian)(xian)的(de)(de)載(zai)(zai)(zai)(zai)流(liu)(liu)(liu)量(liang)(liang)(liang)(liang)高(gao)。 這是(shi)(shi)(shi)(shi)(shi)為(wei)什么呢？影響(xiang)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)(xian)、電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)載(zai)(zai)(zai)(zai)流(liu)(liu)(liu)量(liang)(liang)(liang)(liang)的(de)(de)外(wai)在(zai)要素許多(duo)，如敷(fu)設(she)(she)方法(fa)、敷(fu)設(she)(she)方位、環(huan)境穩度等等。影響(xiang)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)(xian)、電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)載(zai)(zai)(zai)(zai)流(liu)(liu)(liu)量(liang)(liang)(liang)(liang)的(de)(de)內涵要素是(shi)(shi)(shi)(shi)(shi)其(qi)原料(liao)(liao)。 內涵要素中，當電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)(xian)、電(dian)(dian)(dian)(dian)纜(lan)(lan)芯(xin)(xin)線(xian)(xian)(xian)(xian)(xian)(xian)都(dou)是(shi)(shi)(shi)(shi)(shi)銅(tong)導(dao)體時(shi)(shi)，絕(jue)緣(yuan)(yuan)資料(liao)(liao)的(de)(de)答應(ying)長(chang)時(shi)(shi)間工作溫(wen)度是(shi)(shi)(shi)(shi)(shi)影響(xiang)其(qi)載(zai)(zai)(zai)(zai)流(liu)(liu)(liu)量(liang)(liang)(liang)(liang)的(de)(de)要害。 YJY電(dian)(dian)(dian)(dian)纜(lan)(lan)和BYJ電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)絕(jue)緣(yuan)(yuan)層與(yu)YJV電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)絕(jue)緣(yuan)(yuan)層是(shi)(shi)(shi)(shi)(shi)同(tong)(tong)一種資料(liao)(liao)，都(dou)是(shi)(shi)(shi)(shi)(shi)YJ(交(jiao)聯聚乙(yi)烯(xi))，其(qi)絕(jue)緣(yuan)(yuan)最(zui)高(gao)運(yun)(yun)(yun)(yun)轉(zhuan)溫(wen)度為(wei)90℃，所以其(qi)長(chang)時(shi)(shi)間運(yun)(yun)(yun)(yun)轉(zhuan)載(zai)(zai)(zai)(zai)流(liu)(liu)(liu)量(liang)(liang)(liang)(liang)是(shi)(shi)(shi)(shi)(shi)根(gen)(gen)本相同(tong)(tong)的(de)(de)。 而VV電(dian)(dian)(dian)(dian)纜(lan)(lan)、BV導(dao)線(xian)(xian)(xian)(xian)(xian)(xian)的(de)(de)絕(jue)緣(yuan)(yuan)層都(dou)是(shi)(shi)(shi)(shi)(shi)V(聚氯乙(yi)烯(xi))，其(qi)長(chang)時(shi)(shi)間運(yun)(yun)(yun)(yun)轉(zhuan)載(zai)(zai)(zai)(zai)流(liu)(liu)(liu)量(liang)(liang)(liang)(liang)是(shi)(shi)(shi)(shi)(shi)根(gen)(gen)本相同(tong)(tong)，其(qi)絕(jue)緣(yuan)(yuan)最(zui)高(gao)運(yun)(yun)(yun)(yun)轉(zhuan)溫(wen)度為(wei)70℃，比YJ(交(jiao)聯聚乙(yi)烯(xi))最(zui)高(gao)運(yun)(yun)(yun)(yun)轉(zhuan)溫(wen)度低20℃，所以其(qi)載(zai)(zai)(zai)(zai)流(liu)(liu)(liu)量(liang)(liang)(liang)(liang)相應(ying)地(di)會小(xiao)。 下(xia)面列新圖集19DX101-1《修建電(dian)(dian)(dian)(dian)氣(qi)常用(yong)數據》為(wei)例，在(zai)敷(fu)設(she)(she)方法(fa)（敷(fu)設(she)(she)在(zai)明敷(fu)導(dao)管內）、環(huan)境溫(wen)度下(xia)（30℃）均相同(tong)(tong)的(de)(de)條(tiao)件下(xia)，銅(tong)芯(xin)(xin)YJV電(dian)(dian)(dian)(dian)纜(lan)(lan)、GYJSYJ電(dian)(dian)(dian)(dian)纜(lan)(lan)、GYJS電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)(xian)的(de)(de)載(zai)(zai)(zai)(zai)流(liu)(liu)(liu)量(liang)(liang)(liang)(liang)
可見，YJV電(dian)(dian)纜與GYJSYJ電(dian)(dian)纜的(de)絕(jue)緣層相同(tong)都是YJ（交聯聚乙(yi)烯），僅(jin)僅(jin)外護套不(bu)相同(tong)，所以其載流量(liang)根本共(gong)同(tong)，GYJS電(dian)(dian)線(xian)的(de)絕(jue)緣層也是YJ（交聯聚乙(yi)烯），電(dian)(dian)線(xian)比(bi)電(dian)(dian)纜少了一層外護套，平等條件(jian)下(xia)，載流量(liang)稍微有些進步(bu)。相同(tong)的(de)，VV電(dian)(dian)纜與BV電(dian)(dian)線(xian)也相同(tong)遵(zun)照(zhao)該規則(ze)，這兒不(bu)再贅述。
別的，關于載(zai)流量(liang)的查詢，主張直接參(can)看電(dian)(dian)(dian)線GB/T 16895.6-2014《低壓電(dian)(dian)(dian)氣設(she)備(bei)第5-52部分(fen)：電(dian)(dian)(dian)氣設(she)備(bei)的挑選和裝置布線體系(xi)》，按XLPE(交聯聚乙(yi)(yi)烯)、EPR（乙(yi)(yi)丙橡膠）、PVC（聚氯乙(yi)(yi)烯）來(lai)查詢相應電(dian)(dian)(dian)纜、電(dian)(dian)(dian)線的載(zai)流量(liang)。
