Low Smoke Fire-Survival Cables Manufacturer In Srinagar

RBICAB Low Smoke Fire-Survival Cables are engineered to provide critical circuit integrity while minimizing hazardous smoke emissions during a fire. These cables maintain essential power and signal transmission in extreme heat, thanks to advanced low-smoke, zero-halogen materials. They are the preferred choice for emergency systems in enclosed public spaces—such as hospitals, tunnels, subways, and high-rises—where visibility and air quality during evacuation are vital for survival.

The specialized LSZH (Low Smoke Zero Halogen) compounds ensure significantly reduced release of opaque, choking smoke and toxic gases, creating safer escape routes. Combined with mica-based fire-resistant insulation, these cables deliver exceptional thermal endurance, high dielectric strength, and reliable mechanical performance even under prolonged fire exposure.

RBICAB’s dedication to environmental and life safety is reflected in the stringent validation every Low Smoke Fire-Survival Cable undergoes to meet global fire safety standards. Designed for easy installation, long service life, and dependable operation, these cables offer total confidence for applications where fire performance and human safety are inseparable.
