​​Shanghai Shenghua's NYY-FE Fire Resistant Cables: The Ultimate Circuit Integrity Solution for High-Rise Safety​​

In the critical first minutes of a fire, standard cables fail catastrophically—melting into toxic smoke and cutting power to life-saving systems. ​​Shanghai Shenghua Power Group Cable​​ engineers ​​NYY-FE and NYCY fire-resistant cables​​ to defy this fate, combining mica-barrier technology, zero-halogen materials, and 900°C heat resistance to keep emergency systems operational when every second counts

​​Triple-Layer Fire Defense: The Shenghua Engineering Standard​​

1. ​​Mica Firewall Core​​:

   • Copper conductors wrapped in ​​mica tape​​ withstand ​​750°C+ for 90+ minutes​​, maintaining circuit integrity during fires—exceeding IEC 60331 and BS 6387 standards
     
     
   • Unlike standard PVC cables, mica prevents conductor exposure even at direct flame contact, ensuring fire alarms and evacuation lighting stay online
     
     

2. ​​XLPE + LSZH Armor​​:

   • ​​Cross-linked polyethylene (XLPE) insulation​​ enables long-term operation at ​​90°C​​ (vs. PVC’s 70°C limit), resisting electrical degradation and short-circuit temperatures up to ​​250°C​​
     
     
   • ​​LSZH (Low Smoke Zero Halogen) sheathing​​ reduces toxic gas emissions to ​​<0.5% HCl​​ (per IEC 60754-1) and smoke density to ​​>60% light transmittance​​ (IEC 61034), critical for visibility during evacuations
     
     

3. ​​Flame-Retardant Armoring​​:

   • Galvanized steel wire armor (for multi-core) or aluminum wire (single-core) adds mechanical protection while meeting ​​ZA/ZB/ZC/ZD flame-retardant classifications​​
     
     

​​Certified for Life-Saving Applications​​

Shenghua’s cables comply with the EU’s strict post-Grenfell regulations, including:

• ​​CPR Euroclass B2ca​​: 40% lower smoke emission than required
  
  
• ​​BS 7671 Amendment 2​​: Mandatory for UK high-rise safety systems
  
  
• ​​IEC 60331 & EN 50200​​: Validated 180-minute circuit integrity (FE180 rating)
  
  

​​Installation Advantages: Precision for Complex Projects​​

• ​​Bending Flexibility​​: Multi-core cables require only ​​15× outer diameter​​ bends (vs. 20× for single-core), easing routing in tight spaces
  
  
• ​​Sub-Zero Resilience​​: Preheating enables installation at ​​-30°C​​, with operational stability from ​​-40°C to 90°C​​
  
  
• ​​Color-Coded Conductors​​: Simplified wiring alignment per BS/IEC standards (e.g., 5-core: Blue/Brown/Black/Grey/Yellow-Green)

Conductor: Class 1/2 annealed bare copper solid or strands. This wires are formed into final conductor in the stranding machines under strict quality surveillance.

Insulation: Cross linked polyethylene compound or PVC is insulated over the conductors by extrusion process.The raw materials and thicknesses of Insulation are maintained as per standards and conform to IEC60502/BS7870 Standards as the case may be.

Xlpe Insulated Power Cable are identified either by colour or by numbers as follows:
No. of cores Identification
Old Colour coding New Colour coding as per BS
1 Red or Black Brown or Blue
2 Red & Black Brown, Blue
3 Red, Yellow Blue Brown, Black, Grey
4 Red, Yellow, Blue & Black Blue, Brown, Black, Grey
5 Red, Yellow, Blue, Black, Y/G Blue, Brown, Black, Grey & Y/G

Armour : When armouring is required, the armour consists of single layer of galvanised steel wires/galvanized steel tapes.
The armour is applied helically as per standards.
Single core cables are armoured with Aluminium Wires or Copper wires based on requirement.

Outersheath : Standard cables are manufactured with Extruded black PVC. Outersheath is embossed or printed with the information required by relevant standards.
Special FR, FRLS, FRRT, LSF, MDPE compounds are used for outersheathing of cables, to suit customer’s specific requirements.

Operating characteristics

1, Long-term allowable operating temperature of cable conductor ≤70°C
2, Highest working temperature of cable in case of short circuit (the longest lasting time is not over 5s): ≤300mm2 cable conductor ≤160°C, ≥300 mm2 cable conductor≤ 140°C.
3, The laying temperature should over 0℃,Permissible bending radius of cable:for single core unarmored cable, should be no less than 20 times of it’s outer diameter ; for multi-core unarmored cable, should be no less than 15 times of it’s outer diameter
