66–500kV XLPE Insulated Power Cables | IEC 60840 & IEC 62067 Compliant
Our 66–500kV XLPE Insulated Power Cables are designed for high-voltage and extra-high-voltage (EHV) power transmission systems. Manufactured in strict compliance with IEC 60840:2011 and IEC 62067:2011, these cables deliver exceptional electrical performance, thermal stability, and long-term reliability for critical grid infrastructure.
Whether you are building a substation, an offshore wind farm, or an underground urban transmission network, our XLPE cables provide a safe, efficient, and durable solution for bulk power delivery.
| Standard | Voltage Range | Scope |
|---|---|---|
| IEC 60840:2011 | 30 kV (Um=36 kV) up to 150 kV (Um=170 kV) | Extruded insulation cables and accessories for HV transmission |
| IEC 62067:2011 | Above 150 kV (Um=170 kV) up to 500 kV (Um=550 kV) | Extruded insulation cables for EHV transmission |
Wide Voltage Range: Covers 66kV, 110kV, 132kV, 220kV, 330kV, 400kV, and 500kV.
XLPE Insulation: Cross-linked polyethylene provides excellent dielectric strength, low partial discharge, and high thermal resistance.
High Current Capacity: Suitable for bulk power transmission with low transmission losses.
Robust Construction: Metallic screen, water-blocking layers, and protective sheath for underground, submarine, and tunnel installation.
Long Service Life: Designed for 30+ years of continuous operation under demanding conditions.
IEC Compliant: Fully tested to IEC 60840 and IEC 62067 type test requirements
