產(chǎn)品介紹/ PRODUCT PRESENTATIONZRBYJV22-0.6/1KV 4*150+1*70生產(chǎn)執(zhí)行標(biāo)準(zhǔn) GB12706.1.2等同采用電工委員會IEC60502。
產(chǎn)品使用特性
1、電纜導(dǎo)體允許工作溫度不超過70℃；
2、短路時（zui長持續(xù)時間不超過5秒），電纜導(dǎo)體的zui高溫度不超過160℃；
3、敷設(shè)電纜時的環(huán)境溫度應(yīng)不低于0℃。
ZRBYJV22-0.6/1KV 4*150+1*70產(chǎn)品性能：
1、產(chǎn)品依據(jù)GB/T12706-2002國家標(biāo)準(zhǔn)。
2、局部放電試驗：額定電壓Uo為18kV及以下電纜放電量<20PC;額定電壓Uo為18kV以上電纜放電5PC。.
3、20℃導(dǎo)體直流電阻率:銅芯≤0.017241Ωmm2/mo 鋁芯≤0.028Ωmm2/m。
4、燃燒性能（阻燃電纜）根據(jù)GB/T18380-2001標(biāo)準(zhǔn)進(jìn)行試驗。
使用特性：
1、電纜的zui高工作溫度為90℃。
2、電纜敷設(shè)時環(huán)境溫度應(yīng)不低于0℃，裝電纜彎曲半徑應(yīng)大于電纜外徑的20倍。
3、在發(fā)生短路時，導(dǎo)體的zui高溫度應(yīng)不大于250℃，持續(xù)時間不超過5秒。
4、敷設(shè)溫度應(yīng)不低于0℃。
5、短路時，導(dǎo)體的zui高溫度應(yīng)不大于160℃，持續(xù)時間不超過5秒。
6、電纜用于額定電壓0.6/1、1.8/3、3.6/6、6/6、6/10、8.7/10、8.7/15、12/20、21/35、26/35KV輸配電系統(tǒng)。
7、YJV YJLV適用于室內(nèi)外敷設(shè)，可經(jīng)受一定的敷設(shè)牽引，但不能承受機(jī)械外力作用的場合。單芯電纜不允許敷設(shè)在鐵磁性材料管道中。YJV22，YJLV22適用于埋地敷設(shè)，能承受機(jī)械外力作用，但不能承受大的拉力。
