YJV、VV是两(liang)种绝缘材(cai)料不(bu)(bu)同的(de)电(dian)缆(lan)。一般室内永久性(xing)工程都倾向于(yu)(yu)选择YJV电(dian)缆(lan)。VV电(dian)缆(lan)一般用于(yu)(yu)低(di)压(ya)系统(tong)较多(duo), YJV电(dian)缆(lan)则多(duo)用于(yu)(yu)高(gao)压(ya)系统(tong)。YJV电(dian)缆(lan)在耐温,耐压(ya),耐腐蚀上都优于(yu)(yu)VV电(dian)缆(lan),但价值也不(bu)(bu)菲,除了(le)这几点(dian),这两(liang)种电(dian)缆(lan)还有(you)许多(duo)差异,下(xia)面(mian)金(jin)联宇(yu)电(dian)缆(lan)就带咱们深化(hua)了(le)解(jie)一下(xia)吧(ba)。

 10KV金联宇电力电缆

一、底子差异:

  1、YJV—铜芯(xin)交联聚乙烯绝缘聚氯乙烯护套电力电缆(lan)。

  VV—铜芯聚氯(lv)乙烯绝缘(yuan)聚氯(lv)乙烯护套电(dian)力电(dian)缆(lan)。

  2、YJV—电(dian)压等级(k V):1~500。

  VV—电压等级(k V):1~6。

  3、正(zheng)是因(yin)为材料(liao)不(bu)同(tong), 所以VV与YJV电(dian)缆容许(xu)长期作业最高(gao)温度不(bu)同(tong):

  VV电(dian)(dian)缆(lan)护套是(shi)热塑(su)性材料的,VV电(dian)(dian)缆(lan)(VLV)类电(dian)(dian)缆(lan)导体工作最高(gao)额定温(wen)度(du)为(wei)摄氏70度(du),短路时(保持的时刻小于(yu)5秒)最高(gao)温(wen)度(du)不逾(yu)越(yue)摄氏160度(du)。

  YJV电缆(lan)(lan)护套是(shi)热(re)固(gu)性材料的(de),YJV电缆(lan)(lan)(YJLV)类电缆(lan)(lan)导体(ti)工(gong)作最(zui)高(gao)额(e)定温度(du)为摄氏(shi)(shi)90度(du),短路时(shi)(保(bao)持的(de)时(shi)刻(ke)小于(yu)5秒)最(zui)高(gao)温度(du)不逾越(yue)摄氏(shi)(shi)250度(du)。

  二(er)、两者(zhe)在出产设备(bei)和工艺制(zhi)造上也(ye)有差异的:

  VV为塑(su)力缆(lan)(lan),YJV即交联(lian)电缆(lan)(lan),其绝缘层功(gong)用优于塑(su)力缆(lan)(lan)。

  YJV只(zhi)是在(zai)绝缘材料(liao)上做(zuo)了交联处理提高了耐热温度,而 VV没有。

  YJV电缆作(zuo)业(ye)温度(du)达90度(du),而VV只需70度(du),同截面积(ji)YJV电缆载流量大。

  YJV从长(zhang)远看比VV好(运用的寿命长(zhang)等(deng))。

  尽管VV电(dian)(dian)(dian)(dian)(dian)缆(lan)(lan)功用没(mei)有(you)YJV电(dian)(dian)(dian)(dian)(dian)缆(lan)(lan)的健壮,但(dan)金联(lian)宇电(dian)(dian)(dian)(dian)(dian)缆(lan)(lan)通过不(bu)断研讨和技(ji)术创新,逐步(bu)提升了VV电(dian)(dian)(dian)(dian)(dian)缆(lan)(lan)的功用,并结(jie)合其(qi)他(ta)特性和利益,出产出阻(zu)(zu)燃(ran)型的VV电(dian)(dian)(dian)(dian)(dian)缆(lan)(lan),阻(zu)(zu)燃(ran)型电(dian)(dian)(dian)(dian)(dian)力(li)电(dian)(dian)(dian)(dian)(dian)缆(lan)(lan)的主要(yao)特征就是(shi)不(bu)易(yi)着火(huo)(huo)(huo)或着火(huo)(huo)(huo)后(hou)延燃(ran)仅(jin)约(yue)束在(zai)必定(ding)的范围内,适(shi)宜敷设在(zai)宾(bin)馆、车站、化工、石油(you)途径、矿山、电(dian)(dian)(dian)(dian)(dian)站、地(di)铁、高层建筑等对电(dian)(dian)(dian)(dian)(dian)缆(lan)(lan)有(you)阻(zu)(zu)燃(ran)要(yao)求的场合。耐(nai)火(huo)(huo)(huo)型电(dian)(dian)(dian)(dian)(dian)缆(lan)(lan)除有(you)一般电(dian)(dian)(dian)(dian)(dian)力(li)电(dian)(dian)(dian)(dian)(dian)缆(lan)(lan)的特性外(wai),还具有(you)在(zai)假如(ru)发生火(huo)(huo)(huo)灾(zai)燃(ran)烧时,仍(reng)能(neng)保(bao)证在(zai)必定(ding)时刻内正(zheng)常通电(dian)(dian)(dian)(dian)(dian)的特性。十分适(shi)合于火(huo)(huo)(huo)灾(zai)报警、消防设施、急迫涣散(san)等火(huo)(huo)(huo)灾(zai)应急系统的配电(dian)(dian)(dian)(dian)(dian)。
