Shanghai Shenghua Cable Group PVC Sheath 3Cx300 Three Core XLPE Insulated Power Cable

Three Core Copper Conductor XLPE Insulation 26/35KV 3Cx300 Electrical Cable

Powering Critical Infrastructure: Shanghai Shenghua’s 35kV XLPE Cable Solutions for High-Voltage Reliability

In high-stakes energy transmission systems—from urban substations to industrial megaprojects—​​voltage stability and operational safety define success​​. Shanghai Shenghua Cable Group engineers uncompromising resilience with its ​​26/35kV 3Cx300 XLPE Insulated Power Cable​​, featuring triple-shielded copper conductors and industrial-grade armoring for mission-critical power networks.

Engineering Excellence: The Shenghua Difference

​​Multi-Layered Defense Architecture​​

1. ​​Conductor​​: Class 2 stranded copper (IEC 60228-compliant) ensures optimal conductivity and flexibility, minimizing resistive losses at 300mm² cross-sections
   
   
2. ​​EMI Shielding​​: Dual extruded semi-conductive layers + copper tape screen neutralize electromagnetic interference from transformers or heavy machinery
   
   
3. ​​Insulation​​: XLPE core withstands 250°C short-circuit spikes (5 sec) and continuous 90°C operation—40% higher thermal tolerance than PVC alternatives
   
   
4. ​​Sheathing​​: Flame-retardant PVC (FR-PVC) options comply with EN 60332-1-2, suppressing fire propagation in tunnels or industrial plants
   
   

Performance Benchmarks: Where Shenghua Dominates

Applications Demanding 35kV XLPE Cables

1. ​​Urban Power Grids​​
   Direct-buried Shenghua cables (STA/SWA armoured) prevent soil compression and rodent damage in subway networks and hospitals, with LSOH sheathing reducing toxic fumes during fires
   
   
2. ​​Heavy Industry​​
   Copper conductors handle 300mm² cross-sections for crane systems and compressors in steel mills—supporting 600A+ short-circuit currents
   
   
3. ​​Renewable Energy Farms​​
   XLPE insulation resists salt/UV degradation, while FR-PVC sheathing protects against abrasion in wind/solar trench installations
