      1、產品的電氣性能和物理機械性能與普通同類產品相
      同;
      2、電纜的載流量和普通同類產品相同;
      3、耐火特性應符合GB/T19666-2005標準要求:電纜在
      燃燒試驗期間2A熔絲不熔斷。
      4、耐火電纜的參考外徑,截面在25mm
      2
      及以下的比普通
      同型號的產品規格大15%,截面在25mm
      2
      以上的比普通同型
      號產品規格大25%。
      1: Electric performance and mechanical & physical
      performance of cable is the same to common cable in
      similar category.
      2: Current-loading capacity of cable is the same to
      common cable in similar category.
      3: Fire resistant performance shall meet the requirement of GB/T19666-2005 standard. 3A fuse wire won’t
      break during burning test period.
      4: Out diameter of ?re resistant cable with cross section 25mm
      2
      or lower is bigger than that of common cable
      by 15%. Out diameter of fire resistant cable with cross
      section more than 25mm
      2
      is bigger than that of common
      cable by 25%.
      六、使用注意事項 Cautions
      1、電纜接頭時,導體和絕緣之間應用四層云母帶重疊繞
      包扎緊作為耐火層,其它施工方法與同類產品*;
      2、電纜應嚴格避免銳器損壞,否則會降低電纜的耐火性
      能。
      1: Four layers of mica tape should be wrapped
      around between insulation and conductor as ?re resistant
      layer in connection of cable. Other installing measures
      may be taken according to that for similar type cable.
      2: User should strictly avoid damage on cable with
      sharp-edged objects. Otherwise it would affect ?re resistant performance of cable.
      七、交貨要求 Delivery length
      允許根據雙方協議長度交貨;長度計量誤差不超過
      ±0.5%。
      Delivery length of cable depends on both agreements
      with length error allowance of ±0.5%
