ABC Twisted Aluminum Cable 216 416 3*70+54.6 Overhead Aluminum Cable Abstract​ 1. Product Overview​ ABC Twisted Aluminum Cable, available in specifications 216, 416, and 370+54.6, is a high-performance overhead power cable designed for low-voltage distribution networks. "ABC" stands for Aerial Bundled Cable, featuring multiple twisted aluminum conductors integrated into a single insulated bundle. The numerical designations indicate conductor configurations: 216 (2 conductors of 16mm²), 416 (4 conductors of 16mm²), and 370+54.6 (3 phase conductors of 70mm² plus a neutral conductor of 54.6mm²). This twisted structure enhances installation efficiency and operational safety, making it ideal for urban, rural, and industrial power distribution.​ 2. Structural Composition​ 2.1 Conductors​ All conductors are made of high-purity 1350 series aluminum with 61% IACS conductivity, ensuring efficient current transmission. The 16mm² conductors consist of 7 strands (1.7mm diameter each), while 70mm² and 54.6mm² conductors feature 19 strands (2.2mm diameter each). The stranded design enhances flexibility, allowing easy bending during installation, and improves tensile strength to withstand overhead stresses.​ 2.2 Insulation and Bundling​ Each conductor is insulated with 0.8-1.2mm thick XLPE or HDPE, providing excellent dielectric strength (>20kV/mm) and UV resistance. The twisted configuration bonds insulated conductors with a thin web, maintaining 2-3mm spacing for electrical isolation while creating a unified bundle. This design reduces wind load, simplifies handling, and prevents phase-to-phase short circuits.​ 3. Performance Characteristics​ 3.1 Electrical Performance​ Current-Carrying Capacity: 16mm² conductors carry 80-90A; 70mm² conductors handle 180-200A; 54.6mm² neutral conductors support 150-160A (30°C ambient).​ Voltage Rating: Designed for 0.6/1kV systems, suitable for low-voltage distribution.​ Low Losses: DC resistance at 20°C is 1.15Ω/km (16mm²), 0.34Ω/km (70mm²), ensuring minimal power loss.​ 3.2 Mechanical and Environmental Performance​ Tensile Strength: Breaking load ranges from 3.5kN (216) to 12kN (370+54.6), enabling spans up to 60 meters.​ Temperature Resistance: Operates at -40°C to +90°C, with XLPE insulation tolerating short-term overloads up to 130°C.​ Durability: UV-stabilized insulation resists sunlight degradation; moisture barriers prevent water ingress, ensuring 25+ years of service life.​ 4. Application Scenarios​ Residential Areas: 216 and 416 cables connect homes to distribution lines, handling typical household loads.​ Commercial Zones: 4*16 cables serve shops and offices, supporting multiple circuits.​ Industrial Facilities: 3*70+54.6 cables power small factories, with higher capacity for machinery.​ Rural Networks: All specifications excel in remote areas, with long-span capability reducing pole requirements.​ 5. Conclusion​ ABC Twisted Aluminum Cable combines efficient design, durable materials, and versatile performance. Its twisted structure, reliable conductors, and robust insulation make it a cost-effective solution for low-voltage overhead distribution, ensuring safe and uninterrupted power delivery across diverse environments.
