Featured Cables
applications
Fire performance cables are used in a variety of critical applications, including:
● Fire Alarm Systems: Ensuring reliable operation of fire detection and alarm systems.
● Emergency Lighting: Maintaining illumination during power outages caused by fire.
● Communication Systems: Supporting continuous communication for emergency services.
● Life Safety Systems: Powering essential safety systems in hospitals, airports, and other public facilities.
● Control Circuits: Ensuring the operation of vital control systems in industrial environments.
Construction
Fire performance cables are constructed with high-quality materials designed to resist fire and minimize smoke and toxic gas emissions. Key components include:
● Conductors: Made of copper or aluminum, providing excellent electrical conductivity.
● Insulation: High-temperature resistant materials such as mica tape, silicone rubber, or LSZH (Low Smoke Zero Halogen) compounds.
● Sheathing: Fire-resistant outer sheath made of LSZH or other flame-retardant materials.
● Armoring: Optional steel wire or tape armoring for additional mechanical protection.
● Fire Barriers: Fire Barriers: Mica tape or other fire-resistant barriers to prevent fire propagation.
Types of Fire Performance Cables
Fire Resistant Cables
● Construction: These cables typically feature mica tape or other fire-resistant barriers around the conductor, high-temperature insulation, and a durable outer sheath.
● Applications: Used in critical systems requiring continuous operation during a fire, such as fire alarms and emergency lighting.
● Standards: Compliant with IEC 60331 for circuit integrity under fire conditions.
Low Smoke Zero Halogen (LSZH) Cables
● Construction: Insulated and sheathed with LSZH compounds that emit minimal smoke and toxic gases when exposed to fire.
● Applications: Ideal for use in public buildings, transportation systems, and areas with high human occupancy where smoke inhalation and toxicity are concerns.
● Standards: Meets IEC 61034 for smoke emission and IEC 60754 for halogen-free properties.
Flame Retardant Cables
● Construction: Designed with flame-retardant materials to prevent the spread of fire along the cable.
● Applications: Used in general building wiring and installations where flame spread must be controlled.
● Standards: Adheres to IEC 60332 for flame retardance.
