标  准: 本产品按国家标准GB12706-2002或国际电工委员会IEC60502-1:2004标准制造型  号: VV,VLV一铜(铝)芯聚氯乙烯绝缘、聚氯乙烯护套电力电缆VV,VLV一铜(铝)芯聚氯乙烯绝缘、聚乙烯护套电力电缆

用  途: 供固定敷设在额定交流电压UO/U为0.6/1KV及以下的室内、架空、电缆沟道、管道内的输配电力线路用。 铠装电缆是指电缆外绝缘层内包有一层铁皮,反之则是非铠装。

YJV(电缆)和VV(电缆)区别 首先,产品的命名不同,所代表的含义也不同: YJV绝缘用的是交联聚的:

VV为塑力缆,YJV即交联电缆,其绝缘层性能优于塑力缆。 YJV只是在绝缘材料上做了交联处理提高了耐载流量大。 VV类电缆导体运行最高额定温度为摄氏70度,短路时(持续时间小于5秒)最高温度不超过于5秒)最高温度不超过摄氏250度。 YJV从长远看比VV好(使用寿命长等),但比VV贵。从短路允许的VV电缆的各项参数都要高。 在民用建筑中推荐使用YJV,其载流量比VV的大,更为主要的是在电气火灾VV的环保性能差些。在民用,核电等领域VV已基本被YJV取代,但是在很多的工业企业,VV应用还是非常

也不同: YJV绝缘用的是交联聚乙烯. VV绝缘用的是聚氯乙烯. 其次,二者在生产设备和工艺制造上也有区别

缘材料上做了交联处理提高了耐热温度,而 VV没有。 YJV电缆工作温度达90度,而VV只有70度,同截面积YJV电缆时间小于5秒)最高温度不超过摄氏160度。 YJV类电缆导体运行最高额定温度为摄氏90度,短路时(持续时间小),但比VV贵。从短路允许的最高度看:YJV为250度,VV为160、140。 从技术经济指标看,三芯的YJV比大,更为主要的是在电气火灾时,由于其绝缘材料不含氯,燃烧时不会产生有毒气体。所以也就是说多的工业企业,VV应用还是非常广泛的,原因是它的价格便宜。
