Secondary Conductor Triplex 7 Strand AWG 1/0 50mm² Aluminium Gammarus​ The Secondary Conductor Triplex 7 Strand AWG 1/0 (50mm²) Aluminium Gammarus is a high-performance solution for secondary power distribution, featuring three 7-strand 1/0 AWG aluminum conductors in a twisted triplex configuration. Crafted from 1350-H19 aluminum alloy (61% IACS conductivity), it delivers 150A continuous current at 90°C, ideal for 1kV single-phase systems.​ Each 50mm² conductor comprises 7 strands (3.0mm diameter) twisted at 12× lay length, enhancing flexibility (bend radius 8× diameter) for overhead/underground transitions. The triplex design integrates two phase conductors and one neutral, reducing installation time by 35% vs. separate conductors. UV-stabilized XLPE insulation withstands -40°C to 90°C, ensuring 35-year service in diverse climates.​ Compliant with ASTM B230 and IEC 60228, it balances tensile strength (180MPa) and lightweight handling (0.65kg/m). Priced competitively for utility networks, it excels in residential subdivisions and light commercial feeders, merging durability, conductivity, and cost efficiency.
