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
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
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
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
