Olfeld High Voltage Cables (6.6–33kV) are engineered to deliver safe, efficient, and reliable power transmission in medium- to high-voltage applications. Designed for power plants, substations, industrial facilities, and infrastructure projects, these cables ensure minimal energy loss, excellent electrical performance, and long-term operational reliability under demanding conditions.
Our high voltage cables are constructed with stranded copper or aluminum conductors, XLPE (Cross-Linked Polyethylene) or EPR insulation, semi-conductive layers, and robust metallic screen or tape shielding for enhanced electrical integrity and fault protection. A galvanized steel wire (SWA) or tape armouring is incorporated to provide mechanical protection against impact, crushing, and rodent damage, while the outer PVC or PE sheath offers UV, chemical, and weather resistance, ensuring suitability for both underground and outdoor installations.
Tested to international standards (IEC, BS, and IS), Olfeld’s high voltage cables offer low dielectric losses, high thermal stability, and superior short-circuit performance. They are available in single-core and three-core configurations, supporting voltage ratings from 6.6kV to 33kV, with optional fire-retardant or low-smoke zero-halogen (LSZH) jackets for enhanced safety in public or enclosed environments.
Ideal for utilities, oil & gas, mining, industrial automation, and renewable energy projects, Olfeld high voltage cables are trusted where safety, efficiency, and long-term durability are non-negotiable. By combining precision manufacturing and rugged design, these cables ensure uninterrupted power delivery in the most demanding applications.
