Fire Resistance Cable & Flame Retardant Cables | LSZH Fireproof Cabling for Safety-Critical Installations

Fire Resistance Cables and Flame Retardant Cables are essential components in the design of safety-critical electrical systems where fire risk mitigation is a top priority. These cables are engineered to either resist ignition or maintain power supply during a fire, helping to protect lives, maintain emergency services, and reduce structural damage. Ideal for fire alarm systems, emergency lighting, public address circuits, and building safety controls, these cables meet strict low-smoke, zero-halogen (LSZH) standards and provide reliable performance even under extreme heat and smoke conditions.

Product Features

Fire Resistance and Circuit Integrity

Fire-resistant cables are designed to maintain electrical functionality during a fire for a specified period. They are crucial for systems that must operate during emergencies, such as alarms, fire detection, or life-support equipment.

Flame Retardant Performance

Flame retardant cables are designed to resist the spread of fire along their length, reducing fire propagation through cable trays or bundled installations.

Halogen-Free and Low Smoke Emission

Constructed with LSZH (Low Smoke Zero Halogen) sheathing, these cables do not emit toxic or corrosive gases, ensuring clearer visibility and safer evacuation routes during a fire.

Environmental and Safety Standards

Compliant with global fire safety regulations, including smoke cube testing and acid gas emission limits. PVC or halogenated cable types do not meet these criteria.

Easy to Recycle and Install

Made from recyclable, halogen-free compounds. Designed for flexibility in routing and installation across industrial, residential, and commercial environments.

Understanding the Difference: Flame Retardant vs Fire Resistant

• Flame Retardant Cables: Prevent fire from spreading across the cable surface but may not maintain circuit operation during a fire.
• Fire Resistant Cables: Maintain electrical circuit integrity under fire conditions, continuing to function for a specific period.

Common Use Cases

• Fire alarm systems in commercial and residential buildings
• Emergency voice and evacuation communication systems
• Industrial control and instrumentation under fire exposure
• Safety-critical electrical circuits in high-rise developments
• High-temperature or fire-risk environments such as factories and transport hubs
