Industrial Plants Steel Wire Outdoor Armoured Electrical Cable 6.6KV - 35KV
Power Uninterrupted: Shanghai Shenghua’s Armoured Electrical Cable for Extreme Industrial Environments
In high-voltage industrial ecosystems—from steel plants to offshore wind farms—electrical resilience isn’t just critical; it’s non-negotiable. Shanghai Shenghua Cable Group delivers mission-critical power security with its Steel Wire Armoured (SWA) Electrical Cables, engineered for 6.6kV–35kV transmission in outdoor, underground, and industrial applications where mechanical stress, EMI, and extreme temperatures threaten operational continuity.
Engineering Resilience: Shenghua’s 11-Layer Defense System
Shenghua’s SWA cables deploy a meticulously layered architecture to conquer industrial hazards:
- Conductor: Class 2 stranded bare copper (IEC 60228-compliant) for optimal conductivity and flexibility
- EMI Shielding: Dual semi-conductive layers + copper wire screen neutralize electromagnetic interference—critical near transformers or heavy machinery
- Insulation: XLPE core withstands 250°C short-circuit temperatures (5 sec) and continuous 90°C operation, outperforming PVC alternatives
- Armouring: Galvanized steel wire/tape (SWA/STA) resists crushing loads, rodent attacks, and corrosion in direct-burial or chemical-exposure scenarios
- Sheathing: FR-PVC/LSOH options provide flame retardancy (EN 50265-2-1) and UV/chemical resistance

Where Shenghua’s SWA Cables Excel
-
Industrial Power Backbones
- Steel mills, chemical plants, and ports deploy Shenghua’s YJV32/YJLV42 series (steel wire armouring) for crane systems and compressors, leveraging 630mm² copper conductors to sustain 630A+ loads in soil
- Flame-retardant (ZR) variants prevent fire spread in oil/gas facilities.
-
Renewable Energy Grids
- XLPE insulation resists salt/UV degradation, while SWA armour protects against rock abrasion in wind/solar farm trenches
-
Urban Infrastructure
- Direct-buried STA cables (YJV22/YJLV22) power subway networks and hospitals, with LSOH sheathing reducing toxic fumes during fires
Global Standards, Localized Innovation
Shenghua’s cables exceed certifications:
- Quality: ISO 9001, ISO 14001, KEMA, RoHS
- Safety: CCC, P3C, EN 50265-2-1 flammability rating.
- Testing: 63kV/5min AC withstand voltage (IEC 60502-2)
