BVV電線是BV電線衍生出來的,是比BV線多了一層護套的電線,金環宇電線電纜小(xiao)編為大(da)家介(jie)紹(shao)下BVV電(dian)線(xian)?BVV電(dian)線(xian)的(de)含義(yi)和BVV電(dian)線(xian)型號規格。
一(yi)、bvv是什么電線?
bvv電線全(quan)稱銅芯聚氯(lv)乙烯絕緣聚氯(lv)乙烯護套(tao)(tao)圓型護套(tao)(tao)線(xian)(xian),又稱輕型聚氯(lv)乙烯護套(tao)(tao)電纜(lan),俗稱硬護套(tao)(tao)線(xian)(xian)。
銅芯(xin)(xin)(硬)布(bu)電線,單芯(xin)(xin)的是圓的,雙芯(xin)(xin)的就(jiu)是扁(bian)的。常(chang)常(chang)用(yong)于明裝電線。
二(er)、BVV線的結構
