4mm 1C Stranded Bare Copper Unshielded Mica Glass Tape XL-LSZH Zyrad 950 Leigh Cable

Allowable Ampacity for 4mm 1C Stranded Bare Copper Unshielded Mica Glass Tape XL-LSZH Zyrad 950 Leigh Cable: 100 Amps

About:

• The Zyrad 950 Leigh Cable is a high-performance cable designed to ensure safety and reliability in environments where fire resistance and low smoke emissions are critical. It is constructed with advanced materials, including mica glass tape and an XL-LSZH (Cross-linked Low Smoke Zero Halogen) sheath, to offer superior protection and performance in high-risk settings.

Also Known As:

• High-temperature fire-resistant cable
• LSZH fire survival cable
• Single-core mica glass tape cable
• Low smoke, zero halogen cable

Application:

• Fire Alarm Systems: Used to maintain the integrity of fire alarm systems during a fire.
• Emergency Lighting: Ensures that emergency lighting remains functional during and after exposure to fire.
• Industrial Settings: Ideal for use in refineries, chemical plants, and other industrial environments where fire hazards are present.
• Public Infrastructure: Suitable for installation in airports, tunnels, subway systems, and other public infrastructure where safety is paramount.
• Marine Applications: Used on ships and offshore platforms where fire safety standards are stringent.

Standard:

• BS EN 50200: Ensures performance under fire conditions, particularly for fire detection and alarm systems.
• BS 6387: Tested for fire resistance, covering categories C, W, and Z.
• IEC 60331-21: Specifies fire resistance and the ability to maintain circuit integrity during fire.
• IEC 60332-1: Defines the cable’s flame retardant properties.
• IEC 60754-1/2: Confirms the cable is halogen-free with low acid gas emission.
• BS 7211: Standard for low smoke, zero halogen cables, ensuring minimal smoke production and toxicity during a fire.

Construction:

• Conductor: Stranded bare copper, providing a balance of flexibility and electrical conductivity.
• Insulation: Mica glass tape, which offers high resistance to heat and fire, protecting the conductor in case of a fire.
• Sheath: XL-LSZH (Cross-linked Low Smoke Zero Halogen) outer sheath, providing additional protection against fire, with low smoke emissions and no halogens.
• Unshielded: The absence of shielding makes the cable more flexible, although it does not protect against electromagnetic interference (EMI).

Features:

• Fire Resistant: Designed to maintain functionality during and after exposure to fire, ensuring the continuity of critical circuits.
• High-Temperature Endurance: Can withstand high temperatures, making it suitable for use in environments where fires might occur.
• Low Smoke Emission: Emits minimal smoke, which is crucial for maintaining visibility in evacuation routes and reducing inhalation risks.
• Halogen-Free: Produces no toxic halogen gases during combustion, which is important for reducing the harmful effects on humans and equipment.
• Durable and Flexible: Engineered for use in challenging environments, offering flexibility for easy installation while maintaining durability under stress.
