一、援用的規范差別wt7電覽拖鏈電覽-聚氨(an)脂(zhi)鋼(gang)絲繩卷筒電覽-高主動坦克鏈電覽廠(chang)商

傳統成束阻燃ZA、ZB、ZC和ZD種別不屬于阻燃機能的分級。ZA、ZB、ZC、ZD阻燃級別援用的是GB/T 19666-2019《阻燃和耐火電線電纜或光纜公(gong)例》，按照熄滅特征分為ZA、ZB、ZC、ZD四類(lei)；wt7拖鏈電(dian)(dian)(dian)攬電(dian)(dian)(dian)線(xian)(xian)(xian)(xian)線(xian)(xian)(xian)(xian)電(dian)(dian)(dian)攬電(dian)(dian)(dian)線(xian)(xian)(xian)(xian)線(xian)(xian)(xian)(xian)-聚氨(an)脂卷簡(jian)電(dian)(dian)(dian)攬電(dian)(dian)(dian)線(xian)(xian)(xian)(xian)線(xian)(xian)(xian)(xian)-高軟質坦(tan)克鏈電(dian)(dian)(dian)攬電(dian)(dian)(dian)線(xian)(xian)(xian)(xian)線(xian)(xian)(xian)(xian)公(gong)司

A、B1、B2、B3級(ji)(ji)阻(zu)燃級(ji)(ji)別援用(yong)的(de)則是GB 31247-2014《電纜及光纜熄(xi)滅機(ji)能分級(ji)(ji)》，按照火焰舒展長度、熄(xi)滅進(jin)程中熱(re)(re)量(liang)(liang)(liang)開(kai)(kai)釋峰值(zhi)、熱(re)(re)量(liang)(liang)(liang)開(kai)(kai)釋總(zong)量(liang)(liang)(liang)、熄(xi)滅速(su)率(lv)、發生(sheng)煙霧速(su)率(lv)峰值(zhi)、20min發生(sheng)煙霧總(zong)量(liang)(liang)(liang)、煙霧濃度等目標，分為A、B1、B2、B3四(si)個品(pin)級(ji)(ji)；wt7拖鏈數(shu)據(ju)線(xian)(xian)線(xian)(xian)數(shu)據(ju)線(xian)(xian)線(xian)(xian)-橡膠鋼絲繩卷筒數(shu)據(ju)線(xian)(xian)線(xian)(xian)-高撓性坦克鏈數(shu)據(ju)線(xian)(xian)線(xian)(xian)產家
