The Norden Fire-Resistant Cable is designed to maintain critical safety circuits during fire emergencies, featuring stranded bare copper conductors insulated with Mica Tape and XLPE for superior thermal and electrical stability under direct flame, The cores are bound with PES tape and protected by a Flame-Retardant PVC (FR-PVC) or Low Smoke Zero Halogen (LSZH) jacket, ensuring circuit integrity while minimizing smoke and toxic emissions. Its robust construction makes it ideal for fire alarms, emergency lighting, smoke extraction, and other life-safety systems.
