FR CABLE 7-Core × 1.5 mm² Cu/Mica Tape LSZH/LSZH

Introduction

Engineered for critical fire-safety circuits, the FR CABLE 7-Core × 1.5 mm² blends high electrical performance with robust fire protection. In environments such as high-rise buildings, tunnels, and control rooms, this cable safeguards fire detection systems, alarm loops, and emergency lighting. Moreover, its low-smoke, zero-halogen materials help maintain clear evacuation routes when every second counts.

Copper Conductors & Routing Flexibility

We strand each core with seven annealed copper wires, ensuring excellent conductivity and easy bending through tight conduits. Consequently, installers achieve clean runs without kinks or damage. As a result, you encounter minimal voltage drop—only 12.1 Ω/km at 20 °C—thus maintaining stable power delivery across the full circuit length.

Mica Tape Fire Shielding

A 0.12 mm mica tape wraps every insulated conductor, offering an inorganic barrier against direct flame exposure. Therefore, the cable preserves its integrity for up to three hours under fire conditions. Additionally, this layer limits flame spread along the cable, protecting nearby wiring and equipment.

Dual LSZH Insulation & Sheath

First, we apply a 0.80 mm Low-Smoke, Zero-Halogen (LSZH) insulation around each core to reduce toxic gas emission. Next, we cover the entire assembly with a 2.00 mm LSZH outer sheath that resists abrasion, moisture, and UV exposure. Consequently, the cable remains durable and safe in both indoor and outdoor installations.

Compact Dimensions & Handling

Thanks to its flat, seven-core design, this cable measures approximately 14.8 mm in diameter. Each insulated core spans roughly 3.6 mm, enabling neat placement within confined spaces. Furthermore, we supply custom lengths on wooden drums to match your exact project requirements, thereby reducing waste and saving installation time.

Global Standards & Compliance

We build this FR CABLE to meet BS 6004 and IEC 60502 specifications. As a result, it conforms to stringent electrical, mechanical, and fire-safety regulations worldwide. Therefore, specifying this cable grants you full regulatory confidence across diverse applications.

Conclusion

By integrating high-performance copper conductors, mica fire shielding, and dual LSZH layers into a compact format, the FR CABLE 7-Core × 1.5 mm² delivers superior safety and reliability. Whether you wire a fire-alarm loop, install emergency lighting, or equip a control panel, this cable ensures consistent operation and clear escape routes in critical situations.
