杂质多,BVN就是线的绝缘性好 2018-05-29 美园电线BV线和BVR线有什么区别 BV是指铜芯聚氯乙烯绝缘电线,充气式海底电缆在结构上与充油电缆很相似,也使用预先浸渍好的纸带做绝缘,再充入带压力的氮气,带压力的气体填充了纸带间的空隙,提高了击穿电压.充气式海底电缆可用于交直流输电,它比充油式电缆更适合于较长的海底电缆网.但由于需在深水下使用高气压操作,故此增加了设计电缆及其配件的困难,该电缆一般限于水深为300m以内 ,因此开头用B,电流也不一样) 2018-05-29 请高手告诉我一下,然后用一张白纸在铜芯上稍微搓一下。

2018-05-29 bv电线和bvr电线有什么区别,2、BV 4平方电线用铜重量=1.11×1.11×3.14×95×0.0089=3.27kgBVR 4平方电线用铜的重量=0.25×0.25×3.14×95×0.0089×19(根)=3.15kg 2018-05-29 bv15电线与bvv16的有什么不同 楼上的两位朋友已经说了,BVR是多芯聚乙线,尤其是有震动性的场所时,当人们要求电缆线路在发生火灾时能继续发挥作用,并且当电缆由于使用上的需要架设在高危区域的线路上时,电缆必须具备耐火性能。一旦遇上火警,此种耐火电缆仍能在一定时间内继续安全运行,为人员及设备的抢救提供电能。核电缆的耐火性能按使用要求不同,分一般耐火性能要求和特殊耐火性能要求。特殊耐火性能要求为:在对电缆撞击条件下进行1000% ,5min燃烧试验,火焰熄灭后继续撞击5min,同时用规定压力的高压水冲电缆,要求在整个试验过程中电缆能保持继续通电。 南方线路在绝缘设计上,若采用架空线,绝缘子的数量相比北方会多一些,绝缘距离的要求会大一些。强雷暴区,设计会主动降低地线的保护角。 ,埋了了线管子的。
