4 Core Non Armoured XLPE PVC Cable (4×16mm², 4×150mm², 0.6/1kV) is an efficient power transmission line suitable for 0.6/1kV low-voltage systems. It adopts a 4-core design with core cross-sectional areas of 16mm² and 150mm², which can flexibly match the power demand of different equipment.​ The cable conductor is made of high-purity copper with excellent conductivity, which can reduce transmission loss; the insulation layer is made of cross-linked polyethylene (XLPE) with a wide temperature resistance range (-40℃ to 90℃), high insulation resistance, strong anti-aging and chemical corrosion resistance, ensuring stable operation in complex environments. The outer layer is a polyvinyl chloride (PVC) sheath, which has good moisture-proof and anti-corrosion performance and provides basic mechanical protection. Due to the non-armoured design, the cable has better flexibility, making it easy to lay in space-constrained scenarios.​ This cable is widely used in scenarios with low requirements for mechanical protection, such as internal wiring of buildings, power supply for small industrial equipment, and civil distribution systems, providing a safe, efficient and easy-to-install power transmission solution for low-voltage circuits.​

Acyy and Acyy-F low-voltage cables feature a three-phase four-core structure with aluminum core conductors. They are specially designed for low-voltage power systems and widely used in power distribution networks in industrial, civil, and commercial fields.​ Aluminum core conductors offer good conductivity and cost-effectiveness, meeting transmission efficiency requirements while reducing overall costs, making them particularly suitable for large-scale laying scenarios. The three-phase four-core design includes three phase lines and one neutral line, which can stably transmit three-phase alternating current, adapting to three-phase equipment such as motors and transformers, and also meeting the power supply needs of single-phase electrical equipment.​ The two models have slight differences in performance: Acyy cables are suitable for fixed laying in general environments, such as building walls and underground pipelines; Acyy-F cables have better weather resistance and flexibility, and can be used in humid, dusty environments or occasions requiring slight movement, such as outdoor temporary power supply and workshop equipment wiring. Both use standard-compliant insulation and sheath materials, with high insulation resistance and stable voltage resistance, enabling safe operation in low-voltage environments (usually 0.6/1kV and below).​ In addition, this series of cables is easy to install, can be laid by direct burial, pipe threading, overhead, etc., and has low maintenance costs, making it a preferred low-voltage power distribution solution that balances performance and economy.

The underground SWA cable involved in this abstract is a special cable suitable for medium and low voltage distribution systems. Its specification parameters and structural design make it widely applicable in industrial, civil, and infrastructure construction. The rated voltage of this cable is 0.6/1kV, which belongs to the category of low-voltage cables. It is mainly used in distribution networks with a rated voltage of 1kV and below, and can meet the power transmission needs of scenarios such as internal building distribution, underground laying lines, and outdoor engineering. In terms of conductor material, the cable uses high-purity copper core as the conductor. Copper has excellent electrical conductivity and thermal conductivity, with a low resistivity, which can effectively reduce energy loss during current transmission and ensure the efficiency and stability of power transmission. At the same time, copper has high mechanical strength and is not easy to break, which can adapt to complex stress conditions in the underground laying environment. The core design of the cable is 4 cores of 120mm² plus 1 core of 185mm², and this structure takes into account the diversity and safety of power transmission. Among them, the 4 cores of 120mm² are usually used to transmit the phase lines and neutral lines of three-phase alternating current to meet the power supply needs of three-phase loads; while the 1 core of 185mm² has a larger cross-section, which is generally used as a grounding wire (PE line). Its larger cross-sectional area can reduce the grounding resistance, improve the reliability of the grounding system, and in the event of leakage or short-circuit faults, it can quickly conduct the fault current into the ground to ensure the safety of personnel and equipment. The insulation layer and sheath are made of XLPE (cross-linked polyethylene) and PVC (polyvinyl chloride) materials. As an insulation layer material, XLPE has excellent electrical insulation performance, temperature resistance, and chemical corrosion resistance. Its operating temperature range is wide, and it can operate stably in an environment of -40℃ to 90℃, which can effectively resist the erosion of the insulation layer by moisture, acid, alkali substances, etc. in the underground soil. As a sheath material, PVC has good mechanical strength, wear resistance, and flame retardancy, which can provide solid physical protection for the internal structure of the cable, prevent mechanical damage during laying, and delay the aging effect of the external environment on the cable. In addition, the cable has an SWA (steel wire armoring) structure, that is, one or more layers of steel tape armoring are added inside the sheath. The main function of steel armoring is to enhance the mechanical protection ability of the cable, enabling it to withstand large tension, pressure, and impact force. It is suitable for underground installation methods such as direct buried laying and pipe laying, effectively resisting damage from external factors such as soil pressure and stone extrusion. Overall, this underground SWA cable, with its reasonable structural design, high-quality material selection, and reliable performance parameters, can meet the needs of safe, efficient, and long-term operation in underground distribution environments. It is an ideal choice for low-voltage distribution systems in industrial plants, residential communities, municipal engineering, and other fields.
