Fire Resistant Cable— Manufacturer & Supplier
Fire resistant cables maintain circuit integrity during a fire — continuing to deliver power to emergency systems (fire pumps, emergency lighting, smoke extraction fans, elevator recall, alarm systems) while the building burns around them. This is fundamentally different from flame-retardant cables, which only resist flame propagation but cannot guarantee continued operation during fire exposure.
Our fire resistant cable range covers three core technologies: mineral insulated copper cables (MICC/BTTZ) providing up to 3 hours of fire survival at 950°C, LSZH (Low Smoke Zero Halogen) cables with mica-tape fire barrier rated to IEC 60331, and silicone rubber insulated cables for moderate fire resistance with excellent flexibility. Each technology serves different project requirements — from the absolute fire integrity demanded in high-rise evacuation systems to the practical balance of performance and installability needed in commercial buildings.
We manufacture to IEC 60331 (circuit integrity), BS 6387 (survival under fire, water, and mechanical shock), BS 7846, and GB/T 19666. Our factory holds CB Scheme certification, and we can supply with LPCB or regional certification for specific market requirements.

| WDZN-YJY | LSZH + Mica tape | 4×25 mm² | 90 min @ 750°C | 26.5 | Fire pumps |
| WDZN-YJY | LSZH + Mica tape | 4×95 mm² | 90 min @ 750°C | 42.0 | Elevator recall |
| WDZN-YJY22 | LSZH + Mica + STA | 4×16 mm² | 90 min @ 750°C | 24.0 | Underground routing |
| GN-KFV | Silicone insulated | 4×2.5 mm² | 30 min @ 750°C | 14.0 | Control circuits |
BTTZ is rigid — requires special termination. WDZN-YJY is flexible like standard power cable and installs with conventional methods. Contact us for selection guidance.
MICC vs LSZH+Mica vs Silicone — Choosing the Right Fire Resistant Cable
| Feature | MICC / BTTZ (Mineral Insulated) | WDZN-YJY (LSZH + Mica Tape) | Silicone Insulated |
|---|---|---|---|
| Fire Survival Rating | 3 hours @ 950°C (BS 6387 CWZ) | 90 min @ 750°C (IEC 60331) | 30 min @ 750°C |
| Smoke Emission | Zero — inorganic materials only | Very low (LSZH sheath) | Low |
| Flexibility | Rigid — requires special bending tools | Flexible — installs like standard cable | Very flexible |
| Termination | Special sealing glands required | Standard cable glands | Standard cable glands |
| Water Resistance During Fire | Excellent (BS 6387 'W' rated) | Good with intact sheath | Moderate |
| Mechanical Shock During Fire | Excellent (BS 6387 'Z' rated) | Moderate | Poor |
| Maximum Conductor Size | Up to 240 mm² | Up to 400 mm² | Up to 35 mm² |
| Installation Cost | Highest (skilled labour + special fittings) | Standard (same as power cable) | Standard |
| Best Application | Highest-risk: stairwell pressurization, sprinkler pumps, critical evacuation | Most projects: emergency lighting, fire pumps, general life safety | Control circuits, alarm wiring, moderate-risk areas |
For most commercial building projects, LSZH+Mica (WDZN series) offers the best balance of fire performance, installability, and cost. MICC is reserved for the most critical circuits. Data per IEC 60331 and BS 6387.
Application Scenarios
High-Rise Building Life Safety
Fire resistant cables powering emergency lighting, pressurization fans, fire pumps, smoke extraction, and elevator recall systems. Required by building codes (BS 5839, NFPA 72) to maintain circuit integrity during evacuation.
Metro & Tunnel Systems
LSZH fire resistant cables for tunnel ventilation fans, emergency communication, signaling systems, and traction power auxiliary circuits. Low smoke emission critical in confined underground spaces.
Hospital & Healthcare Critical Power
Fire resistant supply cables for operating theatres, ICU equipment, and life support systems that must remain operational during any fire event. Typically BTTZ or LSZH with 90-minute minimum rating.
Data Centres & Telecom Facilities
Fire resistant feeder cables maintaining power to UPS systems, cooling, and fire suppression during fire events. LSZH sheathing prevents toxic halogen gas release that would damage electronic equipment.
Why Source Fire Resistant Cable From Us
All Three Technologies Under One Roof
MICC, LSZH+mica, and silicone — we manufacture the complete fire resistant cable range. Our engineers can recommend the right technology for your specific fire rating requirement, installation method, and budget.
IEC 60331 Circuit Integrity Tested
Our fire resistant cables are type-tested per IEC 60331 at accredited laboratories. Test reports document fire survival duration at specified temperatures. CB Scheme reports available for international project tenders.
Project Packaging with Power & Control Cables
Fire resistant cables are typically 5-15% of a building project's cable bill. We supply them as part of complete cable packages alongside standard power and control cables — one supplier, one shipment, one set of documentation.
Frequently Asked Questions — Fire Resistant Cable
Q.What types of fire resistant cable do you manufacture?
We produce mineral insulated (MICC/BTTZ), LSZH (Low Smoke Zero Halogen), and silicone rubber insulated fire resistant cables for critical infrastructure.
Q.Which fire resistance standards do your cables meet?
Our fire resistant cables comply with IEC 60331, BS 6387, BS 7846, and GB/T 19666 depending on type. Circuit integrity ratings from 30 minutes to 3 hours.
Q.Where are fire resistant cables typically used?
High-rise buildings, tunnels, metro systems, hospitals, airports, and any critical infrastructure requiring circuit integrity during fire events.
Q.How do I choose between MICC, LSZH, and silicone cable?
MICC provides the highest fire rating but is rigid. LSZH is flexible with low smoke emission. Silicone offers good flexibility with moderate fire resistance. Contact us with your project requirements for a recommendation.
