FR CABLE 3 × 1.5 mm² Hard-Skin Enhanced Fire-Resistant Cable – 300/500 V (LSZH, Fire-Survival Grade)

Introduction

In life-safety systems, uninterrupted power to fire detection, alarm circuits, and emergency lighting can save lives. The FR CABLE 3 × 1.5 mm² Hard-Skin cable delivers that reliability under fire conditions. Moreover, its low-smoke, zero-halogen (LSZH) materials minimize toxic gas, aiding safe evacuation. Designed for rigorous environments, this cable balances mechanical toughness with proven fire-survival performance.

Unmatched Fire Performance

We engineer this cable to meet PH30, PH60, and PH120 ratings. Consequently, it sustains full operation for up to 120 minutes at 300/500 V, even when directly exposed to flame. Independent tests confirm that circuit resistance and voltage remain within tolerance during extended fire exposure. Therefore, your alarms, voice-evacuation systems, and exit lighting continue functioning until occupants reach safety.

Conductor Types & Voltage Rating

Rated for 300/500 V, this cable handles standard fire-safety loads without overheating. For core sizing, we offer:

• 1.5 mm² – 2.5 mm²: Class 1 solid copper (BS EN 60228) for steady current delivery.

• 4 mm²: Class 2 stranded copper (BS EN 60228) to simplify routing in tight bends.
  By matching conductor construction to current needs, you avoid voltage drop and reduce installation time.

Fire-Resistant Insulation Layers

Mica/Glass Tape Shield: We wrap each conductor in 0.12 mm of inorganic mica/glass tape. This barrier resists temperatures above 750 °C and prevents sheath collapse.
Silicone-Rubber Overmold: Over the tape, we apply fire-rated silicone rubber that remains flexible under heat. Consequently, the cable resists cracking and maintains circuit integrity when competing cables fail.

Screening & Outer Sheath Protection

To block radiant heat and electromagnetic interference, we include an AL/PET (aluminium/polyester) overall screen. Then, we encase the assembly in a 1.60 mm LSZH hard-skin sheath. As a result, the cable withstands mechanical abuse and emits minimal smoke and no halogen gases during fire exposure. This combination safeguards both equipment and building occupants.

Mechanical Durability & Temperature Range

The hard-skin jacket resists abrasion, crushing, and impact during installation. Simultaneously, the cable performs reliably from –40 °C to +90 °C, making it suitable for cold storage, unheated plant rooms, and sun-exposed rooftops. Furthermore, a minimum bending radius of six times the cable diameter lets you route it through tight conduits without damaging the cores.

Installation & Identification Features

We print clear polarity and phase markings on the jacket every meter to speed up termination. Additionally, color-coded cores—Brown, Black, and Grey plus a Bare Earth—simplify wiring. Because the seven-core assembly remains neat under the sheath, you complete cable pulls faster and reduce installation errors.

Standards Compliance & Testing

We manufacture this cable to exceed:

• BS 5839-1:2013 Clause 26.2(e) for fire-alarm circuits

• BS 8434-2 for up to 120 minutes of fire resistance

• RoHS Directive for zero hazardous substances

Each reel undergoes rigorous in-house tests—verifying electrical continuity, insulation resistance, and fire performance. Consequently, you receive a cable that meets global life-safety requirements, reel after reel.

Applications & Support

Ideal for high-rise residential towers, hospitals, schools, and transport hubs, this cable serves:

• Fire detection and alarm loops

• Voice-evacuation and public-address circuits

• Emergency lighting and exit signage

• Firefighter communication lines

Our technical team provides layout reviews, tray-fill calculations, and onsite training to ensure a smooth, code-compliant installation.

Conclusion

By combining mica/fire-survival shielding, silicone-rubber overmolds, AL/PET screening, and an LSZH hard-skin sheath, the FR CABLE 3 × 1.5 mm² achieves exceptional fire-survival performance. It maintains circuit integrity for two hours, resists mechanical and environmental stresses, and supports safer evacuations with minimal smoke. When seconds matter most, specify this cable for uncompromised life-safety reliability.
