Conquer Harsh Environments with Shenghua’s Armored Submarine Cables: Waterproof Design for Extreme Reliability
Engineered for Saltwater, Underground & Offshore Challenges
As global demand for subsea power transmission surges—propelled by offshore wind farms, inter-island grids, and cross-border energy projects—the need for corrosion-resistant, waterproof cables has never been greater. With the submarine cable market projected to hit $32.86 billion by 2032 (CAGR 8.5%)
, Shanghai Shenghua Cable delivers future-proof solutions designed to thrive in the most demanding environments, from saline seabeds to humid tunnels.
⚙️ Core Innovation: Triple-Layer Armored Defense
-
Stainless Steel Armor (Single-Core Cables)
- Ultimate Corrosion Resistance: Ideal for saltwater immersion, resisting electrochemical degradation in marine environments. Perfect for submarine wind farms like the UK’s 190-km Eastern Green Link project
- Deep-Water Endurance: Rated for depths up to 8,000m
, outperforming conventional designs limited to 500m
-
Steel Tape Armor (Multi-Core Cables)
- Crush & Rodent Protection: Shields against rock abrasion, ship anchors, and rodent bites in underground ducts and coastal installations.
- Torsional Stability: Withstands mechanical stress during laying and operation, critical for dynamic projects like the Java-Bali interconnector
-
IP68 Waterproof Sealing
- PVC/FR-PVC Sheath: Prevents moisture ingress with KEMA-tested sealing. Combined with XLPE insulation (90°C operational stability), it ensures lifetime performance even in flooded trenches or tidal zones
High-Voltage Prowess: 35kV Transmission for Offshore Grids
- Cross-Border Power Sharing: Supports AC/DC transmission up to 35kV, enabling long-distance projects like Denmark’s 1,400 MW Viking Link
- Emergency Overload Capacity: Withstands 160°C during peak loads (e.g., island tourism surges in Bali)
- Zero Electrical Losses: XLPE insulation minimizes dielectric dissipation, crucial for efficiency over 700-km HVDC links
Proven in Critical Global Projects
- Offshore Wind: Deployed in North Sea wind farms, withstanding salt spray and tidal forces.
- Island Interconnectors: Key supplier for Indonesia’s Java-Bali 150kV cable, transferring 130 MVA to power 2.3 million tourists annually
- Port Machinery & Oil Rigs: Flexible Class 5 copper conductors endure constant movement in floating platforms
Why Shenghua Outperforms Competitors
- Customization in 7 Days: Tailor armor (steel/aluminum), sheath colors (red/black/yellow-green), and standards (IEC 60502, DIN, ICEA)
- Certified Reliability: ISO, CE, KEMA, RoHS, and GB/T 12706 compliance
- Anti-Corrosion Tech: Stainless steel armor outlasts traditional materials in pH-imbalanced soils and seawater.
"Shenghua’s armored cables solved our Bali Strait challenge—surviving 8-knot currents and saline seabeds with zero maintenance."
