​​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​​

1. ​​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

2. ​​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

3. ​​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."
