NG-A fire resistant mineral insulated cable takes copper as conductive core, matched with inorganic mineral insulating material and metal outer sheath. Its flexible structure solves the hard construction defect of traditional rigid fireproof cables, making laying and bending much easier.
The inorganic mineral insulation material owns outstanding high temperature resistance and fireproof performance.
It can keep normal power supply under long-time open fire baking, effectively avoiding power failure caused by fire accidents. The whole cable does not contain flammable plastic materials, no toxic smoke will be released when burning, greatly improving safety of fire escape in buildings.
This low voltage fireproof cable is equipped with complete specifications of different cores and cross-sections. It can be laid indoors, in cable shafts, wall ducts and public passageways, widely used for fire emergency power supply lines of various construction projects.
Product Advantages
Excellent fire resistance to maintain power supply in fire scene.
Flexible structure convenient for bending and complex pipeline construction.
Inorganic insulation non-toxic smokeless when burned, high safety.
Solid copper conductor stable transmission with low energy loss.
Long service life and strong aging resistance for long-term building use.
