Product Description

Product Overview

The Fire-Resistant LSZH Cable 4x2.5 mm² Copper, Steel Wire Armoured (SWA) is a low voltage safety cable designed to maintain circuit integrity in fire conditions and withstand mechanical stress in demanding environments.

Constructed with a copper conductor, Mica + LSZH fire-resistant insulation, and a galvanized steel wire armour, it combines fire resistance, halogen-free emissions, and physical protection in one solution. This makes it ideal for use in critical infrastructure installations where both fire safety and mechanical strength are required, such as underground public transport systems, airports, tunnels, and industrial plants.

Application

This cable is designed for:

• Tunnels and subways, where fire-resistance and mechanical protection are both required

• Airports, data centers, and critical infrastructure

• Underground cabling in public or industrial buildings

• Emergency circuits in high-traffic or exposed locations (fire alarms, smoke extract systems)

• Outdoor or harsh environments where rodents, impacts, or pressure may damage standard cables

Key Features

• Conductor: Solid or stranded copper, Class 1 or 2 (EN 60228)

• Insulation: Fire-resistant Mica tape + LSZH insulation

• Armour: Galvanized steel wire armour (SWA) for enhanced mechanical protection

• Outer Sheath: LSZH compound, halogen-free and flame-retardant

• Core Configuration: 4x2.5 mm²

• Voltage Rating: 0.6/1kV

• Fire Resistance: IEC 60331 or BS 6387 CWZ - circuit integrity up to 90 min

• Low Smoke & Halogen-Free: IEC 60754-1/2 and IEC 61034 compliant

• Mechanical Protection: High resistance to crush, impact, rodents, and accidental damage

• Installation: Suitable for direct burial, outdoor trays, or exposed indoor use

• Color: Red or white sheath, or customized on request
