耐火(huo)母線槽的技術要求：

耐火母線槽外殼采用耐高(gao)溫不低于1100℃的防火材(cai)料，

隔(ge)熱層采用耐高(gao)溫不低(di)于(yu)300℃的絕緣(yuan)材料，

滿負荷運行可達8h以上(shang)，景德封閉(bi)母線，

有的檢測機構出具型(xing)式(shi)檢驗報(bao)告。

防火母線(xian)槽和(he)耐火母線(xian)槽有什么區別

1、耐(nai)(nai)火母(mu)線的外殼和隔(ge)熱層是耐(nai)(nai)高溫≥1100℃的防火材料和耐(nai)(nai)高溫≥300℃的隔(ge)熱材料。該(gai)產品的耐(nai)(nai)火時間分別為60分鐘，90分鐘，120分鐘和180分鐘。溫度達(da)到(dao)920?1050℃時熄滅，滿負荷運轉8小時。

2、防火(huo)(huo)母線槽：普(pu)通母線槽或帶有(you)(you)煙氣的防火(huo)(huo)煙道，并帶有(you)(you)防火(huo)(huo)屏障，某些(xie)殼體上(shang)還涂有(you)(you)防火(huo)(huo)涂料(liao)，可以(yi)御火(huo)(huo)。熱能可以(yi)在規定(ding)時間(jian)內到(dao)達內部，母線槽可以(yi)正常運行，防護火(huo)(huo)溫度達到(dao)800度。耐(nai)火(huo)(huo)時間(jian)為30分鐘(zhong)，40分鐘(zhong)和60分鐘(zhong)。
