4/0 Appaloosa Quadruplex Aluminum Overhead Neutral Supported Multiplex Conductor Service Drop Cable with Bare ACSR Messenger​ The 4/0 Appaloosa Quadruplex Aluminum Overhead Cable integrates four 4/0 AWG aluminum conductors with a bare ACSR messenger, setting a new standard for heavy-duty service drops. Engineered with 1350-H19 aluminum (61% IACS conductivity), each conductor delivers 200A continuous current at 90°C, ideal for 1kV three-phase systems powering large commercial buildings and industrial facilities.​ The quadruplex configuration combines three phase conductors (XLPE-insulated, black) and one neutral (XLPE-insulated, white), supported by a 7-strand ACSR messenger (Galvanized steel core with aluminum strands) for 150m span capability. This hybrid design reduces sag by 40% vs. unsupported quadruplex cables and eliminates separate messenger hardware, cutting installation time by 35%.​ UV-stabilized XLPE insulation withstands -40°C to 90°C, ensuring 35-year service in extreme climates. Compliant with ASTM B230/B232, it balances tensile strength (2,800N bundle) and durability, making it the premium choice for high-load overhead service drops requiring both capacity and structural integrity.
