110kV copper wire shield for HV. Suppresses corona ensures uniform stress. For grid backbone island interconnections.
Application
IEC 60840 110kV copper wire shielded HV cable for high-reliability networks: grid backbone, island interconnections, heavy load feeders, substations, switchgears, and generator connections requiring uniform electric field distribution.
Core Strengths
Undetected corona damages HV insulation. Our copper wire shield suppresses corona, ensures uniform stress distribution, and provides emergency fault return path. CE/TÜV/ISO certified.
Standard
GB11017, IEC60840
Construction
☉〉 Conductor: Stranded copper (class 2)
☉〉 Conductor screen: Semiconductive layer
☉〉 Insulation: XLPE (cross-linked polyethylene)
☉〉 Insulation screen: Semiconductive layer
☉〉 Water‑proof tape: Water‑blocking tape
☉〉 Copper wire screen
☉〉 Inner sheath: PVC or PE
☉〉 Armor: Galvanized steel wire (or non‑magnetic aluminum wire)
☉〉 Outer sheath: HDPE or PVC
Features
☉〉 Rated voltage: 110kV (HV transmission)
☉〉 XLPE insulation – 90°C continuous, 250°C short‑circuit
☉〉 Copper wire screen – uniform electric field, corona suppression, fault return path
☉〉 Water‑proof tape – prevents longitudinal moisture ingress
☉〉 Armor – mechanical protection (crush resistance, tensile strength)
☉〉 Outer sheath – anti‑corrosion, UV resistance, suitable for direct burial or tunnel
☉〉 Ideal for grid backbone, island interconnections, heavy load feeders, substations
☉〉 Installation: direct burial, ducts, tunnels, or aerial (with proper support)
☉〉 100% factory tested to IEC 60840
