110KV Copper wire shielded Power Cable

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
