Technical Properties or Conditions

  • Cable may undergo fire-proof test, reaching the requirement of GB/T18380.3;it may, under the flame temperature below 750-800℃, put1, 000v voltage, and burn for 90 min, and the connecting fuse 3A will not break.
  • Except for conductor, armor layer and certain material under special conditions, all material of cable are combustion-retardant, highly combustion-retardant, and fire-proof material.
  • Finished cable conductor-resistance, insulation resistance, voltage test, current-carrying capacity, DC voltage test after laying and installing and partial discharge, etc, are all similar to various corresponding kinds of common cable kinds.

Cable structure and size: 

         a.  Approx. overall diameter of fire-proof cable is about 1.5-3mm more than corresponding common cable according to different kinds.

         b.  Reference weight of fire-proof cable is about 10-7% more than corresponding common cable according to different kinds.

         c.  Conductor structure and others are equal to corresponding common cable.
