      It is used in the environment with high demand on
      ?re resistant performance such as high-rise building, oil
      ?eld, power station, power plant, mine, chemical industry,
      subway and so on. It is also necessary cable prepared
      for emergency power, fire-flight pump and communication system for elevator. In time of being directly ?red by
      flame, it could endure continually supplying power and
      transmitted signal to keep lighting within certain time (no
      less than 3 hours) for people to retreat safely and also to
      bene?t ?ghting ?re to lower damage.

      )
      五、Technical Performance。
      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、 Cautions
      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 Delivery length
      Delivery length of cable depends on both agreements
      with length error allowance of ±0.5%
