The 185mm² single core cable U1000 RO2V 1*185 copper cable is a high-performance cable specially designed for high-voltage power transmission scenarios. With its extra-large conductor cross-sectional area, high-quality material selection and precise process control, it plays a key role in power systems, industrial engineering and large-scale infrastructure projects.​ The core advantage of this cable lies in its 185mm² extra-large conductor cross-sectional area, using high-purity electrolytic copper as the conductive core. High-purity copper has extremely low resistivity, which can significantly reduce energy loss during current transmission and ensure efficient transmission of high-power electricity. The single-core design gives it lower skin effect in high-voltage DC or AC transmission, reducing local overheating caused by uneven current distribution, and is especially suitable for scenarios requiring large current transmission. At the same time, the copper conductor has excellent ductility and mechanical strength, which can adapt to bending, stretching and other operations in complex laying environments, and is not easy to break after long-term use, ensuring the stability of power transmission.​ In terms of insulation and protection structure, the U1000 RO2V 1*185 cable adopts a multi-level protection design. The outer layer of the conductor is wrapped with a high-voltage resistant cross-linked polyethylene (XLPE) insulation layer. This material has excellent temperature resistance (can work stably in the environment of -40℃ to 90℃), aging resistance and insulation strength, and can withstand a working voltage of 1000V and above, effectively isolating current leakage. The outer part of the insulation layer is covered with a flame-retardant polyvinyl chloride (PVC) sheath (characteristic of RO2V model). The sheath not only has good impact resistance, corrosion resistance and wear resistance, but also has passed strict flame retardant tests. In case of fire, it can delay the spread of flames and reduce the release of toxic smoke, buying time for personnel evacuation and equipment protection.​ In terms of application scenarios, this cable is widely used in incoming and outgoing lines of substations, main power transmission in large industrial plants, distribution trunk lines of high-rise buildings, and convergence lines of new energy projects (such as photovoltaic power stations, wind farms). In substations, it can efficiently transmit high-voltage power from the main transformer to the distribution device; in industrial plants, it can provide stable power for high-power equipment such as large motors and furnaces; in new energy projects, its large current-carrying capacity can meet the power collection needs of multiple groups of power generation equipment. In addition, the single-core structure of the cable is convenient for pipe laying or direct burial installation, adapting to various complex environments such as underground, tunnels and cable trays, with strong installation flexibility.​ In terms of performance indicators, the conductor DC resistance of the cable is ≤0.103Ω/km (20℃), the insulation resistance is ≥1000MΩ·km, and the power frequency withstand voltage test of 10kV/5min does not break down, which fully meets international and domestic high-voltage cable standards. Its excellent comprehensive performance makes it a reliable choice in the field of high-voltage power transmission, providing safe, efficient and durable solutions for various large-scale power projects.
