XLPE Armoured And Unarmoured Cables In Bajpur

RBICAB XLPE Armoured and Unarmoured Cables are high-performance power cables designed for efficient and safe transmission of electrical energy across various industrial, commercial, and residential applications. Manufactured with Cross-Linked Polyethylene (XLPE) insulation, these cables offer excellent thermal, mechanical, and chemical resistance, ensuring long-term reliability even in demanding environments.

Armoured variants are provided with a metallic protective layer, typically of galvanized steel wire or aluminium, offering enhanced mechanical strength, rodent resistance, and protection against external stresses, making them ideal for underground or outdoor installations. Unarmoured variants are lightweight, flexible, and easier to install, suited for indoor wiring or protected conduits where mechanical protection is not a critical requirement.

These RBICAB cables conform to international and national standards for electrical safety, insulation performance, and current-carrying capacity. Their superior insulation reduces energy losses, minimizes overheating, and ensures stable operation under high voltage conditions. Available in various sizes, voltage grades, and configurations, RBICAB XLPE Armoured and Unarmoured Cables are a trusted solution for power distribution networks, industrial plants, infrastructure projects, and renewable energy systems.
