In the field of low-voltage power distribution, cables with a voltage rating of 0.6/1kV are key carriers connecting the distribution network to end-users. Low-cost, high-reliability cable products are even more core choices to meet the needs of urban and rural power grid construction, rural power grid transformation, and industrial auxiliary power supply. The low-cost 0.6/1kV ABC cable and triplex aluminum overhead cable (PE insulated) focused on in this article are high-cost-performance products developed based on this market demand. They combine economy, durability, and environmental adaptability, and can be widely used in various low-voltage overhead power distribution scenarios. In terms of product structure, both cables are designed with practicality and cost control as the core principles. Among them, the ABC cable (Aerial Bundled Cable) adopts a multi-core bundled structure, integrating phase wires and neutral wires into the same cable system at a specific spacing, eliminating the need for additional brackets for phase wires and neutral wires, which greatly simplifies the construction process. The triplex aluminum overhead cable, on the other hand, adopts a three-core parallel or stranded design, where each core is independently insulated before overall protection is applied, making it suitable for scenarios with high requirements for line stability. Both cables use aluminum as the conductor material. Compared with copper conductors, aluminum conductors not only meet the conductive performance requirements for 0.6/1kV low-voltage transmission but also reduce material costs by approximately 40%-50%. Moreover, aluminum has a lower density, which can reduce the self-weight of the cable, lower the load-bearing pressure of the poles and towers in the overhead line, and indirectly reduce the engineering construction cost. In terms of insulation performance, both cables uniformly use PE (polyethylene) as the insulation material, which provides double guarantees for the reliability and economy of the products. PE insulation material has excellent electrical insulation performance and a high breakdown field strength, which can effectively isolate current leakage between cores and ensure the cable operates stably for a long time under 0.6/1kV voltage. At the same time, PE material has strong weather resistance and can resist the impact of harsh outdoor environments such as sunlight, rain, and temperature changes (-40℃ to 60℃), avoiding aging and cracking of the insulation layer and extending the service life of the cable to 15-20 years. In addition, PE material has low processing difficulty and its cost is much lower than that of high-end insulation materials such as cross-linked polyethylene (XLPE), which further helps the product achieve the "low-cost" positioning and meet the needs of power distribution projects with limited budgets. In terms of application scenarios, the two types of cables have strong adaptability and can cover a variety of low-voltage power distribution needs. In the transformation of rural power grids, their low-cost advantage can significantly reduce the total project investment for large-scale wiring, and the overhead design does not require ground excavation, avoiding damage to farmland and rural roads. In the auxiliary power supply of suburban areas and industrial parks, the weather resistance of PE insulation can cope with complex industrial environments and outdoor climates, and the lightweight of aluminum conductors facilitates capacity expansion and wiring on existing poles and towers. In temporary power supply scenarios (such as temporary power for construction projects and emergency disaster relief power supply), the convenient construction characteristics of the two cables can shorten the line construction time and quickly meet the power supply demand. In balancing performance advantages and cost control, the two cables perform prominently. In addition to the direct cost reduction brought by aluminum conductors and PE insulation mentioned earlier, their structural design can also reduce construction and maintenance costs. The bundled structure of ABC cables improves construction efficiency by more than 30%, and the unified protection design of triplex aluminum overhead cables reduces the difficulty and frequency of later line maintenance. At the same time, both cables comply with national standards such as GB/T 12527-2008 "Overhead Insulated Cables for Rated Voltage of 1kV and Below", and meet industry requirements in key performance indicators such as conductor DC resistance, insulation resistance, and voltage withstand strength, ensuring that safety and reliability are not sacrificed on the basis of low cost. In conclusion, the low-cost 0.6/1kV ABC cable and triplex aluminum overhead cable (PE insulated), with their high cost performance, excellent environmental adaptability, and reliable electrical performance, have become ideal choices in the field of low-voltage overhead power distribution. They can not only meet the cost control needs of large-scale projects such as urban and rural power grid construction and rural power grid transformation but also provide stable line support for scenarios such as industrial auxiliary power supply and temporary power supply, which is of great significance for promoting the efficient construction and popularization of low-voltage power distribution networks.
