NH refractory Cable It refers to the cable that can keep safe operation for a certain time under the condition of flame burning. Chinese national standards GB12666.6 (etc.) IEC331 ）Divide the fire resistance test A 、 B Two levels, A Stage flame temperature 950~1000 ℃, continuous fire supply time 90min ， B Stage flame temperature 750~800 ℃, continuous fire supply time 90 min During the whole test, the sample shall withstand the rated voltage specified by the product. Fire resistant cables are widely used in high-rise buildings, underground * * *, underground streets, large power stations, important industrial and mining enterprises and other places related to fire safety and fire rescue, such as fire equipment and emergency guide lamp And other emergency facilities.
Brief introduction of fire-resistant cable model:
NH-BV Fire resistant installation single core wire, single hard core conductor, mica tape wrapped plastic insulated wire, factory packaged.
NH-RVS Fire protection installation twisted pair Wire and cable Multiple copper wire stranded conductor mica tape wrapped plastic insulated wires and cables, which can be coiled or mounted on the shaft.
NH-KVV refractory Control cable , composed of several or more cores NH-BV After the wires are twisted into cables, a layer of sheath shall be put out. Voltage requirements 450/750 Pack with wooden plate.
NH-KVVP Fire resistant shielded control cable NH-KVV On the basis, a layer of copper wire braiding shield is installed at home, NH-KVVP2 Copper tape is used to wrap the shield and pack the wooden disk.
