Application

220kV single-core EHV AWA cable for submarine sections, offshore wind farm connections, coastal power plants, and marine environments requiring non-magnetic armor, high corrosion resistance, and tensile strength. Non-magnetic AWA eliminates magnetic losses. Direct burial, ducts, submarine.

Core Strengths

Steel armor on single-core EHV causes magnetic losses and heating. Our non-magnetic AWA provides mechanical defense without parasitic losses. Ideal for marine and corrosive conditions. ISO/CE certified.

Standard

GB11017， IEC60840

Construction

Conductor: Stranded copper (class 2)

Conductor screen: Semiconductive layer

Insulation: XLPE (cross-linked polyethylene)

Insulation screen: Semiconductive layer

Semi-conductive water-blocking tape

Copper wire screen

Water-blocking tape

Inner covering: PVC or PE

Armor: Aluminum wire (AWA – non‑magnetic)

Outer sheath: HDPE or PVC

Features

Rated voltage: 220kV (EHV transmission)

XLPE insulation – 90°C continuous, 250°C short‑circuit

Non‑magnetic aluminum wire armor (AWA) – eliminates eddy current losses; lightweight, corrosion‑resistant

Copper wire screen – uniform electric field, corona suppression, fault return path

Dual water‑blocking tapes – prevent longitudinal moisture ingress

Ideal for submarine sections, offshore wind, coastal power plants, and corrosive environments

Installation: direct burial, ducts, tunnels, or submarine (with proper protection)

100% factory tested to IEC 60840 / IEC 62067
