The ABC Aerial Bundled Cable (ABC stands for Aerial Bundled Cable) is a high-efficiency power distribution product specifically designed for low-voltage overhead power transmission scenarios. It is compatible with low-voltage power grids (usually 0.6/1kV and below) and adopts two high-quality aluminum-based conductors: AAAC (All-Aluminum Alloy Conductor) and ACSR (Aluminum Conductor Steel Reinforced). Paired with an XLPE (Cross-Linked Polyethylene) insulation layer, it leverages its bundled structure, high-strength conductor, and excellent weather-resistant insulation performance to be widely used in urban and rural low-voltage power distribution networks, rural power grid renovation, residential community power supply, industrial park branch transmission, and power access in remote areas. It provides a reliable, economical, and environmentally adaptable power transmission solution for low-voltage overhead lines and is a core component in modern low-voltage power infrastructure construction.​ In terms of core specifications and conductor characteristics, the cable meets the voltage requirements of low-voltage overhead scenarios, typically with a rated voltage of 0.6/1kV (0.6kV as phase voltage and 1kV as line voltage). It can stably carry the conventional current load of low-voltage power grids, cope with voltage fluctuations in daily electricity use, and avoid insulation breakdown or conductor overheating caused by voltage overload. Two types of conductors—AAAC and ACSR—are available to meet the mechanical and conductive needs of different scenarios: AAAC all-aluminum alloy conductors are made of high-purity aluminum and trace alloying elements (such as magnesium and silicon), combining high conductivity (conductivity up to 61% IACS or higher) and excellent corrosion resistance. They are particularly suitable for corrosive environments such as coastal and humid areas, and their light overall weight can reduce the load pressure on poles and towers; ACSR aluminum-conductor steel-reinforced conductors use a high-strength steel core for support, with aluminum wires twisted on the outer layer. This design not only retains the high conductivity of aluminum but also significantly improves the tensile strength of the conductor (tensile strength up to 120MPa or higher) through the steel core. It is suitable for overhead lines with large spans (such as crossing roads and rivers) or open areas with high wind speeds, and can resist line stretching and shaking caused by strong winds. The cross-sectional specifications of the two conductors cover a wide range (commonly 10mm²-120mm²), allowing users to accurately select models based on line load, span distance, and environmental corrosion degree to ensure long-term stable operation of the line.​ The selection of XLPE material for the insulation layer is one of the core advantages of this cable. Compared with traditional PVC or PE insulation, XLPE has more excellent electrical and weather-resistant performance: in terms of electrical properties, XLPE has extremely low dielectric loss (usually <0.002) and high insulation resistance (>1000MΩ·km), which can effectively reduce energy loss during current transmission and improve power utilization efficiency; in terms of temperature resistance, XLPE can operate at a long-term temperature of up to 90℃ and a short-term overload temperature of up to 130℃, capable of withstanding heat shock from high-temperature exposure in summer and short-term current peaks, avoiding softening and deformation of the insulation layer; in terms of weather resistance, after cross-linking treatment, the molecular structure of XLPE forms a three-dimensional network structure, significantly enhancing its UV resistance and anti-aging ability. In outdoor overhead scenarios, it can resist embrittlement and cracking of the insulation layer caused by direct sunlight, wind, and rain erosion, with a service life of more than 20 years, far exceeding that of traditional insulation materials. In addition, XLPE also has good chemical corrosion resistance, which can resist acid-base pollutants in industrial areas and salt spray erosion in coastal areas, further expanding the environmental adaptability range of the cable.​ The bundled structure is a key design that distinguishes this cable from traditional overhead bare wires. Unlike traditional overhead lines that require separate erection of live wires, neutral wires, and ground wires, the ABC cable bundles multiple insulated conductors (usually including live wires, neutral wires, and ground wires in some models) into a single cable bundle through a dedicated process. This structure brings multiple advantages: first, it simplifies the line layout, reduces the number of overhead lines to be erected, lowers the usage of supporting facilities such as poles, towers, and fittings, and shortens the construction period (construction efficiency is increased by more than 30% compared with traditional lines); second, it avoids exposed conductors, greatly reducing short-circuit faults caused by bird nesting, branch contact, and foreign object 搭接，and reducing the frequency of power outage maintenance (fault rate can be reduced by more than 60%); third, it improves line safety—the insulation layer isolates the conductor from the outside world, effectively preventing electric shock accidents caused by accidental contact by personnel or animals, especially suitable for urban and rural areas with high population density. At the same time, the bundled structure makes the overall outer diameter of the cable smaller and the wind resistance coefficient lower, which can reduce the impact of strong winds and ice coating on the line and improve the line stability under extreme weather.​ From the perspective of scenario adaptability and performance advantages, the characteristics of this cable make it widely applicable in the field of low-voltage overhead. In urban and rural power distribution networks, the AAAC conductor model can be used in coastal or rainy areas to resist humid corrosion; the ACSR conductor model is suitable for main roads or suburban lines with large spans to ensure tensile performance. In rural power grid renovation, the lightweight and bundled design of the cable can reduce the construction difficulty in remote areas, and erection can be completed without large lifting equipment, accelerating the speed of rural power coverage. In the branch transmission scenarios of residential communities and industrial parks, the bundled structure can reduce the space occupied by lines, avoid safety hazards of traditional bare wires to the surrounding environment, and the low-loss characteristic of XLPE insulation can reduce power loss inside communities and parks, improving power supply efficiency. In addition, the cable has strong maintenance convenience: the bundled structure enables faster fault point location without checking individual wires one by one; the anti-aging property of XLPE reduces the frequency of daily inspection and replacement, and only regular visual inspection and insulation resistance testing are required, greatly reducing operation and maintenance costs.​ In terms of quality assurance, this cable strictly complies with international and domestic low-voltage overhead cable standards (such as IEC 60502-2 and GB/T 14049), with full-process control from raw materials to finished products: for conductors, AAAC must comply with GB/T 1179 standards, and ACSR must comply with GB/T 1179 or IEC 61089 standards to ensure that the conductor purity, tensile strength, and conductivity meet the standards; XLPE insulation materials must pass 1000-hour thermal aging tests, UV resistance tests, and dielectric loss tests to ensure long-term stable insulation performance; the bundling process uses automated equipment to accurately control the conductor spacing and insulation layer thickness (insulation thickness error does not exceed ±0.1mm), avoiding defects such as bubbles and impurities. The finished product testing includes voltage withstand test (no breakdown for 1 minute under 1kV voltage), insulation resistance test, conductor DC resistance test, tensile strength test, and weather resistance test (simulating 5000 hours of outdoor environmental aging). Only after all tests are qualified can the product leave the factory, eliminating quality hazards from the source and building a solid line of defense for the safe and stable operation of low-voltage overhead lines.​ Generally speaking, the ABC Aerial Bundled Cable for low-voltage overhead power lines, with its diverse high-strength conductors, high-performance XLPE insulation, and efficient bundled structure, perfectly adapts to the complex needs of low-voltage overhead scenarios. It not only solves the problems of poor safety and frequent faults of traditional bare wires but also takes into account the mechanical and weather-resistant requirements in different environments. It provides customized solutions for various low-voltage power distribution scenarios such as urban and rural areas, rural areas, and industrial parks, promoting the upgrading of low-voltage power infrastructure towards higher efficiency, safety, and durability.
