- 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.
