    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

    Parameter3×300 SpecificationIndustry Impact
    ​​Current Load​​525A (air) / 520A (soil)Powers heavy machinery in steel mills/data centers
    ​​Test Voltage​​91kV/5min (IEC 60502-2)Exceeds 35kV safety margins by 160%

    ​​Bending Radius​​15× cable diameterSimplifies installation in congested conduits
    ​​Temperature Range​​-20°C to +90°C (fixed)Reliable in Arctic mines or desert solar farms
    ​​Conductor Resistance​​0.0601 Ω/km (20°C)Reduces energy loss by 18% vs. aluminum cores

    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

    Why Global Engineers Trust Shenghua

    • ​​40+ Years of Expertise​​: OEM customization for voltages (3.6kV–36kV), armoring (STA/SWA), and sheaths (PVC/LSOH/FR-PVC)

    • ​​Global Certifications​​: KEMA, CE, RoHS, GB/T 12706.2, with 12-month PICC-backed warranty

    • ​​Rapid Deployment​​: Wooden/steel drum packaging with moisture-proof sealing; 7–15-day delivery for urgent projects

    • ​​Sustainability​​: RoHS-compliant materials reduce environmental impact without compromising durability
