Rz Cable, as a series of cable products focusing on power transmission, occupies an important position in industries, construction, energy and other fields due to its reliable performance and wide applicability. Among them, Rz1-K cable, as a core model in the series, is a power cable with high-purity copper as the conductor. Relying on the excellent conductivity and stability of copper, it has become a key component in power transmission systems. In terms of structural design, Rz1-K cable uses high-purity electrolytic copper as the conductor, with a copper content usually as high as 99.9% or more. This characteristic ensures that the cable has extremely low resistance, which can effectively reduce energy loss during power transmission and improve the overall transmission efficiency. The outer layer of the conductor is wrapped with materials with excellent temperature resistance and insulation properties (such as cross-linked polyethylene or polyvinyl chloride), which not only can effectively isolate current leakage, ensure electrical safety, but also resist the impact of chemical corrosion, mechanical wear and temperature changes in the external environment, thus prolonging the service life of the cable. In addition, some Rz1-K cables are also equipped with an armor layer, which further enhances their impact resistance and pressure resistance, enabling them to adapt to complex laying environments, such as underground direct burial, pipeline laying or overhead erection. In terms of performance parameters, the rated voltage of Rz1-K cable covers a wide range, from low voltage (0.6/1kV) to medium and high voltage (10kV and above), which can meet the needs of different power systems. Its current-carrying capacity varies according to the cross-sectional area of the conductor, usually ranging from tens of amperes to hundreds of amperes, which can stably transmit large currents and ensure the continuity of power supply. At the same time, the cable has good heat resistance, with a long-term working temperature of up to 90℃ or even higher. It can also operate stably in case of short-term overload, which greatly improves the fault tolerance of the system. In terms of application fields, Rz1-K cable is widely used in power transmission systems of industrial enterprises, distribution networks of urban power grids, power supply lines of high-rise buildings, and power collection and transmission of new energy projects (such as photovoltaic power stations and wind farms) due to its excellent performance. In industrial production, it can provide stable power support for large mechanical equipment and ensure the efficient operation of production lines; in urban construction, its reliable insulation and protection performance help reduce power failures and improve the safety and stability of residents' electricity use; in the new energy field, its high current-carrying capacity and weather resistance can adapt to complex outdoor environments, effectively promoting the efficient utilization of clean energy. In summary, as an important product in the Rz Cable series, Rz1-K cable, with high-purity copper conductor as the core, combined with advanced structural design and excellent performance parameters, has shown strong competitiveness in the field of power transmission, providing a solid guarantee for the safe, stable and efficient operation of various power systems.
