Extra Super Voltage Cable
Extra Super Voltage (ESV) Cables are the most advanced category of power transmission cables, specifically designed for ultra-high voltage levels exceeding 500 kV. They serve as the main arteries of modern power grids, enabling the transfer of enormous amounts of electrical energy across vast distances with minimal transmission loss. Engineered for strength, stability, and longevity, these cables ensure reliable power delivery to cities, industries, and national networks where energy demand is at its highest.
Produced using cutting-edge technologies such as triple extrusion, dry curing, and precision shielding, Extra Super Voltage Cables incorporate high-conductivity copper or aluminum conductors, triple-layer XLPE insulation, and multi-layered semiconducting screens. They also feature metallic sheaths, steel wire or corrugated aluminum armoring, and protective outer jackets designed to resist heat, moisture, and mechanical stress. Available in single-core and segmented-core configurations, these cables comply with international standards such as IEC 62067 and IEEE 1299. They are primarily used in cross-country transmission lines, large substations, offshore grid connections, and renewable energy projects requiring ultra-high efficiency.

The superior electrical, mechanical, and thermal properties of ESV Cables make them ideal for both underground and submarine installations. With exceptional dielectric strength, high current-carrying capacity, and resistance to environmental degradation, they guarantee safe and uninterrupted power flow under extreme conditions. Their long service life, reduced maintenance cost, and consistent performance establish Extra Super Voltage Cables as the ultimate solution for modern power infrastructure and energy sustainability.
