Shanghai Shenghua Power Group: Redefining Safety with Customizable
LSZH Cables for Critical Infrastructure
Shanghai Shenghua Cable (Group) Co., Ltd.—China’s #2 cable
manufacturer with 110,000 km annual output and 21
ISO-certified factories—sets a global benchmark in fire safety
with its Low Smoke Zero Halogen (LSZH) Power Cables. Engineered
for high-risk environments like subways, hospitals, and data
centers, these IEC 60502-certified solutions combine zero-halogen
innovation, extreme thermal resilience, and customizable aesthetics
to protect lives and assets worldwide.
1. Advanced Engineering for Life-Saving Performance
- Zero-Halogen Core Technology:
- LSZH Insulation & Sheath: Eliminates toxic fumes (e.g., HCl,
dioxins) during combustion, reducing smoke density to <20% of
traditional PVC cables and ensuring ≥60% light transmittance
for clear evacuation paths
- Corrosion Prevention: PH value of combustion gases maintains
≥4.3 (weak acidity), protecting sensitive equipment in control
panels
- Thermal & Electrical Excellence:
- 90°C Continuous Operation + 250°C Short-Circuit Survival
(5s): Surpasses standard PVC (70°C) in high-heat zones like power
plants
- Ultra-Low Resistance: Class 1/2 annealed copper conductors
minimize energy loss (e.g., 0.0470 Ω/km for 400mm²), cutting
operational costs by 30%
- Customizable Armor & Colors:
- Steel Tape/Wire Armor (WDZA-YJY23/33): Protects against
mechanical stress in underground installations.
- 12+ Custom Colors: Meets BS 7870 standards for phase
identification (e.g., Brown/Blue/Grey for 3-core)
2. Certified Global Compliance & Safety
- Standards: IEC 60502, IEC 60227, GB/T 12706, with optional
BS/DIN/ICEA certification.
- Fire Safety Certifications:
- IEC 60332-1 (Flame Spread), IEC 61034 (Low Smoke), IEC
60754 (Zero Halogen)
- CE/KEMA Marks: Ensures EU/UKCA market access.
3. Technical Superiority Across Applications
Key Specifications (WDZA-YJY Series):
| Conductor (mm²) | Max. DC Resistance (Ω/km) | Diameter (mm) | Current Rating (Air) |
|---|
| 1×1.5 | 12.1 | 7.7 | 22A |
| 1×240 | 0.0754 | 27.7 | 535A |
| 5×150 | 0.124 (per core) | 58.5 | 325A |
Applications:
- Public Transportation (Subways/Airports): LSZH sheath reduces
smoke toxicity in evacuation-critical sites, aligning with EU CPR
regulations
- Data Centers: Halogen-free materials prevent server corrosion
during fires (critical for 5×95mm² server farm wiring)
- Renewable Energy: 90°C thermal stability supports solar/wind
farm connections (WDZA-YJLY aluminum variants cut project costs by
25%)

economy goals
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.
Outer sheath : 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.
