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.
