The 3 Core 150mm² Copper Conductor XLPE Power Cable is an excellent performance and widely used power transmission cable, which plays an important role in the power system.​ The conductor of this cable is made of high-purity electrolytic copper with a purity of over 99.95%. The cross-sectional area of 150mm² endows it with excellent current-carrying capacity, with a DC resistance of ≤0.124Ω/km, which can transmit electricity efficiently and reduce energy loss. The design of three cores makes it suitable for three-phase AC power systems, capable of transmitting A, B, and C three-phase currents simultaneously, meeting the power demand of three-phase equipment and playing a key role in industrial and civil power transmission.​ The insulation layer is made of cross-linked polyethylene (XLPE) material, which forms a three-dimensional network structure after cross-linking treatment, with excellent electrical performance and heat resistance. Its long-term working temperature can reach 90℃, and the short-term overload temperature can rise to 130℃. It can still maintain stable insulation performance in high-temperature environments, with an insulation resistance of ≥1000MΩ·km, effectively preventing electric leakage and short-circuit accidents and ensuring the safety of power transmission.​ The sheath is usually made of polyvinyl chloride (PVC) or polyethylene (PE) materials, with good mechanical strength, wear resistance, and corrosion resistance. The PVC sheath has a tensile strength of ≥12MPa and an elongation at break of ≥150%, which can resist external mechanical impact and chemical erosion, protecting the internal core wires and insulation layer from damage; the PE sheath has more advantages in low-temperature resistance, suitable for use in cold regions.​ In terms of application scenarios, this cable is widely used in the power distribution system of industrial plants to provide power for large motors, production lines and other equipment; in commercial buildings, it can be used as a main cable for power distribution trunks and emergency power supply systems; in municipal engineering, it is suitable for branch lines of urban power grids, street lamp systems, etc.; in the new energy field, such as internal connecting lines of photovoltaic power stations and wind farms, it can also be seen, which can adapt to the special environmental requirements of new energy power generation.​ In the production process, the conductor is made by wire drawing and stranding to ensure that the core wire is tight and the conductive performance is uniform; the XLPE insulation layer is made by extrusion process, and the thickness of the insulation layer is uniform and free of bubbles by precisely controlling the temperature and speed; in the cabling process, the three core wires are stranded in an orderly manner, and fillers are filled to ensure roundness; finally, the sheath is extruded to form a complete cable. Each batch of products must undergo multiple tests such as voltage resistance, insulation resistance, and mechanical performance to ensure that the quality meets the standards.​ The packaging uses wooden or steel reels, the diameter of which is customized according to the length of the cable. The outer layer is wrapped with waterproof film and canvas to prevent moisture and dust. During transportation, special vehicles are used, which are fixed firmly to avoid collision, and it is strictly prohibited to mix with corrosive substances. Sample service is provided, and customers can apply for 1-3 meters of samples for testing. The after-sales guarantee is perfect, with a 24-month warranty period. During this period, if there is a quality problem, it can be replaced or repaired free of charge, and installation guidance and technical support are also provided.
