The XV U1000 R2V 3 Phase 16mm² 5 Core 5g35 copper conductor insulated electrical power cable is a high-performance cable designed specifically for low-voltage three-phase power distribution systems. Its model "XV" indicates the insulation and sheath material properties, "U1000" denotes a rated voltage of 1000V, "R2V" refers to its flexible structure combined with a polyvinyl chloride (PVC) sheath, and "3 Phase 16mm² 5 Core 5g35" specifies the number of cores, cross-section, and conductor specifications. This cable, with its stable conductivity, flexible installation characteristics, and wide applicability, plays an important role in low-voltage power distribution scenarios in industrial, construction, and municipal fields. Its price, influenced by multiple factors such as material costs, production processes, and market supply and demand, presents a reasonable and competitive range.​ In terms of product structure, the core advantage of this cable lies in the combination of multi-core design and high-purity copper conductors. Among the 5 cores, 3 main cores (16mm² cross-section) are used for transmitting three-phase current, and the other 2 auxiliary cores (usually 4mm² or 6mm²) serve as neutral and grounding wires, meeting the requirements of three-phase four-wire or five-wire power distribution systems. It is suitable for power connections of equipment such as motors, distribution boxes, and lighting systems. The conductor is made of 5g35 high-purity electrolytic copper (purity ≥99.95%) through bunch stranding, which not only improves flexibility for bending and laying in narrow spaces (minimum bending radius is 6 times the cable outer diameter) but also ensures excellent conductivity. The DC resistance of the conductor at 20℃ is ≤1.15Ω/km, much lower than industry standards, effectively reducing energy loss during transmission.​ The material selection of the insulation and sheath layers is crucial for the cable's performance. The insulation layer is made of polyvinyl chloride (PVC) with a temperature resistance rating of 70℃, featuring good dielectric properties (volume resistivity ≥1×10¹³Ω·cm) and aging resistance. It can work stably in environments ranging from -15℃ to 70℃, avoiding short circuits or leakage risks. The sheath layer is also made of PVC, added with flame retardants (oxygen index ≥30) and anti-ultraviolet additives, complying with the flame retardancy requirements of GB/T 18380. It also has wear resistance and acid-alkali corrosion resistance, suitable for various installation methods such as indoor exposed laying, trunking laying, or pipe embedding. In addition, the flexible structure design represented by the "R2V" label ensures that the cable is not prone to sheath cracking or conductor breakage in scenarios involving frequent bending or movement (such as mechanical equipment wiring), extending its service life.​ In terms of application scenarios, the 1000V rated voltage and 16mm² cross-section of the XV U1000 R2V cable make it an ideal choice for low-voltage power distribution. In industrial plants, it can be used as power connecting wires for motors, withstanding vibrations and oil pollution during equipment operation. In commercial buildings, it is suitable for power distribution lines from distribution boxes to floor lighting, air conditioners, and other loads, meeting intensive power consumption needs. In municipal engineering, it is often used in power supply lines for street lamp systems and small pumping stations, and its flame retardancy and weather resistance can cope with complex outdoor environments. Meanwhile, the 5-core design eliminates the need for separate grounding wire laying, reducing construction costs and time.​ Regarding price, the market quotation of XV U1000 R2V 3 Phase 16mm² 5 Core cable is affected by various factors. In terms of raw materials, fluctuations in copper prices are a core factor—each meter of cable contains approximately 0.45kg of copper, and for every 1000 yuan/ton increase in copper prices, the cable cost increases by about 0.45 yuan/meter. In production processes, the automation level of bunch stranding, insulation extrusion, sheath forming, and other processes affects labor costs, and advanced production lines can reduce unit costs by approximately 10%-15%. In addition, order quantity, transportation distance, and payment methods can also lead to price differences: bulk purchases (such as over 1000 meters) can enjoy a 5%-8% discount; quotations including transportation and installation services are usually 15%-20% higher than bare cables. The current market reference price is 25-35 yuan per meter, and the specific price needs to be negotiated with suppliers based on actual order details.​ In summary, the XV U1000 R2V 3 Phase 16mm² 5 Core copper conductor cable, with its reliable performance, wide applicability, and reasonable price, has become a cost-effective choice in the low-voltage power distribution field, meeting both safety and efficiency requirements while taking into account economy.
