Overhead insulated cable carries power on poles and towers with a protective covering over each conductor, so lines stay safe in built-up, coastal, and tree-lined areas where bare wire would be a hazard. Each cable runs an aluminum or copper conductor under a cross-linked polyethylene (XLPE) or PE insulation layer, finished with a weather- and UV-resistant outer sheath for long outdoor service. At ZD Cable we build the full overhead-insulated range — from low-voltage Aerial Bundled Cable (ABC) and Service Drop cables to medium-voltage Tree Wire, Covered Line Wire, and Aerial Insulated Cable — each type-tested to the standard your network was designed against.
Selection follows voltage and environment. For low-voltage distribution (≤ 1 kV) — street lighting, service connections, and temporary supply — ABC bundles several insulated cores into one self-supporting cable for fast, low-clearance installation, while Service Drop cables run power from the pole to the building. In medium-voltage networks (typically 10–35 kV), Tree Wire and Spaced Aerial Cable resist phase-to-phase faults from branch contact in wooded corridors; Covered Cable and PVC Covered Conductor add a weather barrier to overhead lines; and ACSR-OC / ACSR-AW-OC pair a covered conductor with a steel-reinforced core for longer spans.
