Application
Overhead Insulated Covered Line Wire is a single-core conductor designed for low-voltage aerial distribution systems, offering enhanced electrical safety and environmental durability compared to bare overhead wires. It consists of a hard-drawn aluminum conductor (or aluminum alloy) covered with a UV- and weather-resistant thermoplastic or cross-linked polyethylene (XLPE) layer.
Unlike fully insulated bundled cables, covered line wire maintains a single-phase open construction, allowing for simpler installation and traditional spacing, while still providing basic protection against accidental contact, tree branches, wind-blown debris, and wildlife. It helps reduce outages and improves public safety in densely populated or vegetated areas.
This cable is commonly used in overhead service drops, secondary distribution networks, and retrofit projects where bare conductors pose safety or maintenance concerns. It supports operating voltages up to 0.6/1kV and is suitable for both urban and rural networks.
