Custom Overhead Insulated Cable Manufacturer — ACSR, AAAC, CAA & ABC Aerial Bundled Cable

ABC (Cavo aereo in bundle) integrates multiple insulated conductors into a single self-supporting bundle. Unlike bare conductors, the XLPE insulation eliminates phase-to-phase and phase-to-ground contact faults caused by tree branches, wind sway, or accidental contact. Installation clearance requirements are significantly reduced, making ABC the preferred choice for urban distribution networks, forested routes, and last-mile connections where conventional bare lines would require frequent maintenance or right-of-way clearing.

Overhead insulated cable and underground (sepoltura diretta) cable are not interchangeable. Overhead cables are engineered for UV resistance, mechanical self-support, and aerial installation methods, while underground cables require armor, moisture barriers, and burial-grade jacket compounds. Using an overhead cable in a direct burial application — or vice versa — will result in premature insulation degradation and does not meet IEC installation standards. Confirm the installation environment before specifying the cable type.

The three conductor types serve distinct engineering priorities. ACSR (Conduttore in alluminio rinforzato in acciaio) provides high tensile strength for long spans or mountainous terrain, using a steel core for mechanical support. AAAC (Tutto il conduttore in lega di alluminio) offers comparable strength to ACSR without the steel core, making it the preferred choice for coastal and high-humidity environments where galvanic corrosion between dissimilar metals is a concern. CAA (Tutto il conduttore di alluminio) delivers the highest conductivity-to-weight ratio and is the most cost-effective option for short to medium spans in moderate loading conditions.

IL 1 kV rating reflects the design scope of this product category: low-voltage (LV) aerial distribution — the final distribution stage from substation secondary winding to end-user connection points. Medium-voltage (MV) or high-voltage (alta tensione) aerial cables require substantially different insulation thickness, conductor construction, and testing protocols under separate IEC standards (per esempio., CEI 60502-2 for MV). If your project involves voltages above 1 kV, contact the engineering team to discuss the appropriate product category.

Core selection depends on the distribution system configuration. A 2-core ABC bundle is typically used for single-phase service drops or two-wire secondary distribution. A 4-core ABC bundle suits three-phase + neutral LV distribution, covering the majority of urban and rural grid extension applications. In some configurations, a separate bare concentric neutral messenger wire is included; confirm with the project engineer whether a 4-core bundle or a 3-core + messenger arrangement is specified in your local grid standard.

SÌ. Standard production covers the cross-sections and core counts listed in the specification table above. For non-standard cross-sections, alternate insulation colors (for phase identification per local grid codes), sequential footage or meter marking, custom drum lengths, or OEM print on the jacket, submit the project specification sheet or marking requirements through the inquiry form. The engineering team will confirm feasibility and lead time based on the specific configuration.
