33kV Three Core Copper Conductor XLPE Insulated Medium Voltage Power Cable

Shenghua 33kV Triplex XLPE Power Cable: The Critical Infrastructure’s Copper-Nerve System

Shenghua redefines resilience for medium-voltage (33kV) power networks with its ​​triple-core copper-conductor XLPE cables​​, engineered to deliver uninterrupted energy for smart grids, industrial hubs, and disaster-prone regions. Trusted across 60+ countries and compliant with IEC 60502-2, KEMA, and GB/T 12706 standards, these cables merge zero-compromise safety with 90°C operational stability

​​Engineering Superiority: Why Copper + XLPE Dominates 33kV Networks​​

1. ​​Triple-Shielded Safety Architecture​​

   • ​​Conductor​​: Compact stranded copper (IEC 60228 Class 2) ensuring 60% lower resistance vs. aluminum, critical for high-current transmission
     
     
   • ​​Insulation​​: Nano-modified XLPE rated for 90°C continuous, 250°C short-circuit (5 sec), and ozone/UV resistance—extending lifespan to 50+ years
     
     
   • ​​Armor​​: Copper tape screen + FR-PVC sheath (IEC 60502 ST2) blocking electromagnetic interference, ideal for urban substations near sensitive electronics
     
     

2. ​​Disaster-Proof Performance​​

   • ​​Seismic Resilience​​: Steel-wire armored (YJV32) variants absorb 12G vibrations, deployed in Japanese bullet train tunnels
     
     
   • ​​Fire Safety​​: Halogen-free LSOH sheath option reduces smoke opacity to ​​<15%​​ (IEC 61034), mandatory for hospitals and petrochemical plants
     
     

3. ​​Efficiency Engineered​​

   • ​​Ultra-Low Losses​​: 3×400mm² configuration achieves ​​0.047Ω/km​​ resistance—slashing transmission waste by 18% vs. industry averages
     
     
   • ​​Current Mastery​​: 3×240mm² carries 460A underground (soil), powering copper smelters without derating
     
     

​​Critical Applications: Where Shenghua Outperforms​​

​​Global Compliance & Customization​​

• ​​Certifications​​: CE, RoHS, KEMA, with bespoke approvals for BS/DIN/ICEA
  
  
• ​​Extreme-Environment Kits​​: Arctic-grade LSOH (-40°C flexibility), termite-resistant coatings, and seismic armor (STA/SWA).

​​Shenghua’s Manufacturing Edge​​

• ​​Precision Scale​​: 20-year ISO 9001 factory, AI-driven defect detection (99.998% consistency), 3,000 km/month capacity

  
  

  
  

• ​​Global Logistics​​: Wooden-iron drum packaging (MOQ 800m); 30% deposit pre-production, 70% pre-shipment
