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
- Conductor: Class 2 stranded copper (IEC 60228-compliant)
ensures optimal conductivity and flexibility, minimizing resistive
losses at 300mm² cross-sections
- EMI Shielding: Dual extruded semi-conductive layers + copper
tape screen neutralize electromagnetic interference from
transformers or heavy machinery
- Insulation: XLPE core withstands 250°C short-circuit spikes (5
sec) and continuous 90°C operation—40% higher thermal tolerance
than PVC alternatives
- 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
| Parameter | 3×300 Specification | Industry 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% 2 5 |
| Bending Radius | 15× cable diameter | Simplifies 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 3 |
Applications Demanding 35kV XLPE Cables
- 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 - Heavy Industry
Copper conductors handle 300mm² cross-sections for crane systems and compressors in steel mills—supporting 600A+ short-circuit currents - 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
