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
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
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
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.

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
