Electrical FRC 4 Core Heat Resistant Cable 1.5mm - 800mm 90℃
Temperature
Engineered for Survival: Shanghai Shenghua’s Fire Resistant Cables
for Critical Infrastructure
In high-risk environments like hospitals, metro tunnels, and
petrochemical plants, circuit integrity during fires is
non-negotiable. Shanghai Shenghua Power Group Cable addresses
this with its FRC 4-Core LSOH Fire Resistant Cables—designed to
maintain power transmission even at 1,000°C for 90+ minutes
while emitting zero toxic smoke
Core Technology: Triple-Layer Fire Defense
- Mica Tape Firewall: Wrapped around copper conductors, mica tape
withstands 250°C during 5-second short circuits and 750°C+ in
prolonged fires, preventing conductor exposure and ensuring
circuit integrity
- LSOH Insulation & Sheath: Halogen-free materials reduce toxic
gas emissions (HCl <0.5%) and smoke density (>60% light
transmittance), aligning with IEC 61034-2 and IEC 60754-1
- XLPE Thermal Stability: Cross-linked polyethylene insulation
enables long-term operation at 90°C, outperforming PVC’s 70°C
limit while resisting electrical degradation
Certified Performance for Global Compliance
Shenghua’s cables exceed international safety benchmarks:
- Standards: IEC 60502, 60331 (fire resistance), 61034 (smoke
density), and GB/T 12706 (China)
- Certifications: CE, RoHS, CCC, and KEMA-tested reliability
- Fire Ratings: Class ZA/ZB/ZC/ZD flame retardancy and 950°C fire
resistance for emergency systems
Installation & Durability Optimized
- Bending Flexibility: Multi-core cables require only 15× outer
diameter bends, easing installation in tight spaces
- Environmental Resilience: Operates at -0°C to 90°C
(preheating below 0°C) and resists chemicals, oils, and mechanical
stress
- Water & Impact Resistance: Withstands sprinkler systems and
falling debris during fires—critical for evacuation safety
Applications Where Failure Is Not an Option
- High-Rise Buildings: Powers fire lifts, smoke control, and
emergency lighting (e.g., NH-YJV32 variant)
- Power Stations & Petrochemical Plants: Ensures uninterrupted
operation of critical control systems
- Metro Tunnels: LSOH properties aid visibility during
evacuations

Packing and shipping
We are capable of meeting the most strict delivery schedules
according to per purchase order. Meeting the deadline is always the
top priority as any delay in the delivery of cable can contribute
to overall project delay and cost overrun.
Cable is supplied in wooden reels, corrugated boxes and coils.
Cable ends are sealed with BOPP self adhesive tape and
non-hygroscopic sealing caps to protect the cable ends from
moisture. The required marking shall be printed with a
weather-proof material on the outsides of drum according to
customer's requirement.
