Copper wire armouring not only enhances the mechanical protection capability of the cable, resisting external impacts such as extrusion and collision, but also has certain anti-corrosion performance, making it suitable for humid or slightly corrosive environments. Galvanized steel wire armouring, on the other hand, is characterized by higher mechanical strength, with outstanding tensile and anti-rolling capabilities. It is especially suitable for scenarios such as underground laying, outdoor exposure, or areas that may be crushed by heavy machinery, such as industrial zones and municipal engineering. Both armouring methods can effectively protect the internal conductor and insulation layer, extending the service life of the cable.​ In terms of performance, this single-core cable shows advantages in many aspects. It has a wide operating temperature range, usually able to operate stably in an environment of -15℃ to 70℃, adapting to different climatic conditions. The flame-retardant property of the PVC insulation layer (in line with relevant standards) can delay the spread of flames to a certain extent, improving the safety of use. In addition, the single-core design reduces interference between cables, facilitating separate laying in complex wiring environments, especially suitable for occasions requiring separate control or signal transmission.​ The application scenarios are very extensive, covering multiple fields: in industrial plants, it is often used to connect large mechanical equipment and power supply for production lines; in construction projects, it can be used as the main power distribution line in buildings, or in areas with mechanical protection requirements such as underground garages and equipment rooms; in outdoor projects, such as street lamp systems and power supply for greening irrigation equipment, the galvanized steel wire armoured version can withstand erosion from natural factors such as wind, rain, and ultraviolet rays; in humid environments such as basements and sewage treatment plants, the anti-corrosion characteristics of copper wire armouring make it an ideal choice.​ In terms of installation and maintenance, although the flexibility of the cable is slightly lower than that of non-armoured cables due to the presence of the armouring layer, it can still be bent and cut with professional tools to adapt to different laying paths (such as threading, underground laying, or wall-mounted 架设). During installation, care should be taken to avoid excessive bending that may cause the armouring layer to break, and terminal treatment should be done well to ensure the tightness of insulation and armouring. In daily maintenance, its robust structure reduces the need for frequent overhauls, and only regular inspections are required to check whether the armouring layer is damaged and whether the insulation layer is aging.​ To sum up, the NYA type 450/750V copper core PVC insulated armoured single-core cable, with the efficient conductivity of copper conductor, stable protection of PVC insulation, and strong protection of the armouring layer, has become a high-quality cable that combines safety, durability, and adaptability, providing a reliable solution for various medium and low-voltage power transmission scenarios.

The 2.5mm² automotive primary wire, featuring PVC insulation and a 105°C temperature rating, is a critical component in modern car electrical systems. Designed as a single-core conductor, it balances conductivity, durability, and heat resistance to meet the demanding requirements of automotive environments, where reliability and safety are paramount. At the core of this wire is a high-purity copper conductor, typically composed of stranded copper strands to enhance flexibility. The 2.5mm² cross-sectional area (equivalent to approximately 13 AWG) ensures it can handle moderate to high current loads, making it suitable for powering essential systems such as lighting, ignition circuits, and accessory connections. The stranded design allows the wire to bend and route easily through the tight spaces of a vehicle’s engine bay, chassis, and interior, accommodating the complex wiring harnesses that connect various components. The copper used is of high quality (99.9% purity), ensuring low electrical resistance and efficient power transmission, which minimizes voltage drop even over longer cable runs within the vehicle. The PVC insulation is a key feature, formulated specifically for automotive use. It provides excellent electrical insulation, with a dielectric strength of at least 15kV/mm, preventing short circuits and electrical leakage that could damage sensitive electronics or cause safety hazards. The insulation is rated to withstand continuous operating temperatures up to 105°C, a critical specification for under-hood environments where heat from the engine, exhaust system, and other components can raise ambient temperatures significantly. This heat resistance ensures the insulation remains stable, avoiding melting, cracking, or degradation that would compromise performance. Additionally, the PVC material is resistant to oils, fuels, greases, and water—common contaminants in automotive settings—further extending the wire’s lifespan. The single-core design simplifies installation and reduces bulk in wiring harnesses, which is essential in modern vehicles where space is limited. Unlike multi-core cables, which are bulkier and less flexible, the single-core structure allows for easier routing through conduits, around engine parts, and between body panels. This design also minimizes weight, contributing to overall vehicle efficiency, a key consideration in electric and hybrid vehicles where weight reduction directly impacts range. In terms of performance, the 2.5mm² wire has a current-carrying capacity of approximately 20-25A under normal operating conditions (at 30°C ambient temperature). This makes it suitable for a range of applications: powering headlights, taillights, and fog lights; connecting ignition coils and fuel injectors; and supplying power to accessories like air conditioning compressors, power windows, and infotainment systems. Its ampacity is derated at higher temperatures (e.g., 16-20A at 105°C) to ensure safe operation, aligning with automotive safety standards that prioritize preventing overheating. Safety is further enhanced by the wire’s flame-retardant properties. The PVC insulation is formulated to self-extinguish if exposed to flame, reducing the risk of fire spreading through the vehicle’s wiring system in the event of a short circuit or external ignition source. This meets stringent automotive safety standards such as SAE J1128, which governs the performance of primary wires in vehicles. The wire is also color-coded according to industry standards, with common colors including red (power), black (ground), and various other hues to denote specific circuits (e.g., yellow for ignition, blue for lighting). This color coding simplifies installation and maintenance, allowing technicians to quickly identify and trace wires during repairs or modifications. Applications of the 2.5mm² automotive primary wire are widespread across all types of vehicles, including passenger cars, trucks, SUVs, and commercial vehicles. In internal combustion engine (ICE) vehicles, it forms part of the wiring harness connecting the battery to the starter motor, alternator, and various sensors. In electric vehicles (EVs) and hybrids, it is used in auxiliary systems such as heating, ventilation, and air conditioning (HVAC), as well as in charging port wiring, where its heat resistance and durability are equally valuable. In summary, the 2.5mm² automotive primary wire with PVC insulation and a 105°C rating is a versatile and reliable component in car electrical systems. Its combination of high-conductivity stranded copper, heat-resistant and chemical-resistant PVC insulation, single-core flexibility, and adherence to safety standards makes it indispensable for powering critical vehicle systems. Whether in traditional ICE vehicles or modern EVs, this wire ensures efficient, safe, and long-lasting electrical performance in the challenging environments of automotive operation.
