Steel Tape Armoured Low Smoke Zero Halogen Cable 1.5mm2 - 800mm2 Eco Friendly
Engineering Resilience: Shanghai Shenghua’s Armoured LSZH Cables for Critical Infrastructure
Shanghai Shenghua Cable (Group) Co., Ltd.—ranked China’s #2 cable manufacturer with 110,000 km annual output and 21 ISO-certified factories—redefines safety in high-risk environments with its Steel Tape Armoured LSZH Cables. Combining military-grade mechanical protection, zero-halogen innovation, and extreme thermal resilience, these IEC 60502-certified solutions safeguard tunnels, hospitals, and industrial plants against fire hazards and physical damage.
1. Triple-Layer Defense: Armor, Safety & Sustainability
- Military-Grade Armor:
- Galvanized Steel Tape Armour (WDZA-YJY23): Absorbs crushing forces up to 3,500 N/cm² in underground installations, outperforming unarmored cables by 70% in impact resistance
- Helical Application: Prevents armor separation during bending (15×[d+D] radius), ideal for serpentine tunnel layouts
- Zero-Halogen Safety:
- LSZH Sheath & Insulation: Eliminates toxic fumes (HCl, dioxins), reducing smoke density to <20% of PVC cables and ensuring ≥60% light transmittance for evacuation clarity
- Eco-Compliance: Halogen-free materials align with RoHS and EU CPR, with combustion gas pH ≥4.3 to prevent equipment corrosion.
- Thermal Resilience:
- 90°C Continuous Operation + 250°C Short-Circuit Survival (5s): Ensures functionality in boiler rooms or chemical plants during overloads
2. Technical Superiority & Global Certifications
Key Specifications (WDZA-YJY23 Series):
| Conductor (mm²) | Armor Thickness | Max. Current (Air) | Smoke Density | Weight (kg/km) |
| 1.5 | 0.2mm | 22A | <20 Ds* | 81 |
| 185 | 0.8mm | 375A | <10 Ds* | 7,271 |
| 400 | 1.2mm | 720A | <5 Ds* | 40,640 |
| Ds = Smoke density (IEC 61034 standard) |
|
|
|

Certifications:
- Safety: IEC 60332-1 (Flame Spread), IEC 61034 (Low Smoke), IEC 60754 (Zero Halogen)
- Global Compliance: CE, KEMA, GB/T 12706, with optional BS/DIN/ICEA marks
3. Applications Redefining Safety
- Underground Tunnels & Subways:
- Steel tape armor resists rockfall and excavation machinery, while LSZH sheath prevents toxic smoke in confined spaces (e.g., 1×400mm² supports 695A in soil)
- Hospital ICU/Operating Theaters:
- BS 7870 Color Coding: Brown/Blue/Grey sheathing simplifies phase identification during emergency maintenance
- Ultra-Low Resistance: 0.047 Ω/km (400mm²) minimizes energy loss for life-support systems
- Chemical Plants & Oil Rigs:
- XLPE insulation withstands hydrocarbon exposure, while armor prevents corrosion from acidic vapors
4. Why Global Engineers Trust Shenghua?

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.
