66KV Copper wire shielded Power Cable

66KV Copper wire shielded Power Cable

Application

IEC 60840 66kV copper wire shielded HV cable for utility substations to urban underground feeders, regional grid backbones, and industrial zone power transmission requiring reliable fault handling and electrical stress control.


Core Strengths

Shield degradation in 66kV systems increases maintenance costs. Our uniform copper wire shielding reduces corona and provides continuous shield conductor for end-to-end grounding. CE/TÜV/ISO certified.


Standard

GB 11017, IEC60840


Construction

Conductor: Stranded copper (class 2)

Conductor screen: Semiconductive layer

Insulation: XLPE (cross-linked polyethylene)

Insulation screen: Semiconductive layer

Copper wire screen (shield)

Water‑proof tape: Water‑blocking tape

Inner sheath: PVC or PE

Armor: Galvanized steel wire (SWA) or steel tape (as required)

Outer sheath: HDPE or PVC


Features

Rated voltage: 66kV (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 / tensile resistance)

Ideal for utility substations, urban underground feeders, regional grid backbones

Installation: direct burial, ducts, or tunnels

100% factory tested to IEC 60840
