With a conductor cross-sectional area of 300mm², it is suitable for medium and low-voltage power transmission scenarios. Relying on high current-carrying capacity, heat resistance stability and reliable mechanical protection, it is widely used in industrial plants, large buildings, energy facilities and other fields that require large-capacity power transmission.​ In terms of structure, the core of the cable is a high-purity copper conductor with a purity of not less than 99.95%. It is made by multi-strand fine stranding process, which not only ensures excellent conductivity (conductivity ≥58MS/m) but also improves the flexibility of the cable, making it easy to lay in complex terrain or narrow spaces. The outer layer of the conductor is wrapped with an XLPE insulation layer, which forms a three-dimensional network molecular structure through chemical or radiation cross-linking. This enables it to have a long-term allowable operating temperature of up to 90°C and can withstand 250°C in short-circuit conditions (within 5 seconds), effectively avoiding the softening or aging of traditional polyethylene insulation at high temperatures, and significantly extending the service life of the cable. Outside the XLPE insulation layer is a PVC sheath, which is added with flame retardants, antioxidants and UV stabilizers. It has excellent wear resistance, corrosion resistance and UV resistance, and can resist mechanical impact, moisture, chemicals and direct sunlight erosion, providing solid protection for the internal structure.​ In terms of performance parameters, the rated voltage of the cable is usually 0.6/1kV (can be customized according to requirements), suitable for AC 50Hz/60Hz power systems. The large cross-sectional conductor of 300mm² endows it with extremely high current-carrying capacity: when laid in air, the current-carrying capacity is about 450-500A; when directly buried in soil, it is about 400-450A, which can meet the power needs of large motors, transformers, central air conditioners and other heavy-duty equipment. In terms of insulation performance, the insulation resistance of the XLPE insulation layer is ≥1000MΩ·km, and the dielectric loss tangent (tanδ) is ≤0.005, ensuring extremely low energy loss during power transmission. In terms of mechanical properties, the minimum bending radius of the cable is 12 times the outer diameter (for fixed laying), which can adapt to a certain degree of bending installation; the PVC sheath has a tensile strength of ≥12MPa and an elongation of ≥150%, which can withstand stretching, extrusion and friction during laying, ensuring the structural integrity during installation.​ In application scenarios, Nyy N2xy Cable 1*300 plays an important role in many fields relying on the advantage of large current-carrying capacity of 300mm²: in the industrial field, it serves as the main cable of the factory to connect transformers and distribution cabinets, providing power for large production lines and heavy machinery; in the energy industry, it is used in the collector lines of wind farms and photovoltaic power stations to centrally transmit scattered electric energy to the booster station; in large buildings, such as the distribution main lines of commercial complexes and high-rise buildings, it supports the power supply of air conditioning, elevators, lighting and other systems in the entire building; in municipal engineering, it is used as an underground cable for the branch lines of urban power grids, connecting substations with residential communities or industrial parks. In addition, the flame retardancy and weather resistance of its PVC sheath enable it to operate stably in humid, dusty or outdoor environments, such as underground garages and open-air substations.​ In terms of installation and maintenance, the cable can be laid by bridge laying, pipe laying or direct burial. During installation, special tools should be used to avoid excessive bending or extrusion to prevent damage to the insulation layer and sheath. Terminal connections need to be equipped with copper joints matching 300mm² conductors, which are fixed by crimping or bolts to ensure good conductivity, and sealed to prevent moisture intrusion. After laying, insulation resistance testing and voltage withstand testing (applying 2.5 times the rated voltage for 5 minutes without breakdown) must be carried out to verify that the cable performance meets the standards. In daily maintenance, regularly check whether the sheath has cracks, bulges or signs of aging, and repair in time if problems are found; for cables exposed to sunlight, sunshades can be added to delay sheath aging and extend service life.​ In summary, Nyy N2xy Cable 1*300 copper conductor power cable (Cu/XLPE/PVC) realizes the unity of high current-carrying capacity, high stability and strong protection through the optimized combination of large-section copper conductor, XLPE insulation and PVC sheath. It is an ideal choice in large-capacity power transmission scenarios, providing a reliable solution for various large-scale power needs.

The 50mm², 35mm², 25mm², 16mm² 4-core armoured copper conductor XLPE insulated cables are a type of power transmission products with both high safety and strong adaptability. Their prices are affected by multiple factors such as specifications, materials, and market supply and demand. They are widely used in medium and low-voltage power distribution systems in industrial, construction, energy and other fields, providing reliable guarantee for power transmission in complex environments.​ In terms of product characteristics, the core advantage of this series of cables lies in the combination of structural design and material performance. The conductor is made of high-purity electrolytic copper (purity ≥99.95%), and the 4-core configuration is suitable for three-phase four-wire power distribution systems. Among them, the single-core conductor diameter of 16mm² cable is about 4.5mm, 25mm² is about 5.6mm, 35mm² is about 6.8mm, and 50mm² is about 8.6mm. The conductivity is all ≥58MS/m, ensuring low-loss power transmission. The insulation layer is cross-linked polyethylene (XLPE), and its thickness increases with the increase of cross-section: 16mm² insulation layer is 1.0mm-1.2mm thick, 25mm² is 1.2mm-1.4mm, 35mm² is 1.4mm-1.6mm, and 50mm² is 1.6mm-1.8mm. It has temperature resistance (long-term working at 90℃, 250℃ in short circuit), aging resistance, and insulation resistance ≥1000MΩ·km. The armouring layer is made of galvanized steel strip or steel wire with a thickness of 0.3mm-0.5mm, forming a mechanical protection barrier with outstanding impact and extrusion resistance, which can withstand radial pressure ≥10kN. The outer sheath is made of PVC or PE material, which is acid and alkali resistant, UV resistant, further improving environmental adaptability.​ In terms of price, this series of cables shows a stepwise change due to specification differences. The market unit price of 16mm² cable is about 35-45 yuan/meter, 25mm² is about 55-65 yuan/meter, 35mm² is about 80-95 yuan/meter, and 50mm² is about 120-140 yuan/meter. Price fluctuations are mainly affected by copper prices - as the core raw material, copper accounts for 60%-70% of the cable cost. For every 1000 US dollars/ton fluctuation in international copper prices, the unit price of cables fluctuates by about 5%-8%. In addition, armouring materials (steel strip/steel wire), insulation layer technology (cross-linking degree) and production scale also affect pricing: galvanized steel wire armouring is 10%-15% more expensive than steel strip, high-density XLPE insulation is 8%-12% more expensive than ordinary XLPE, and bulk purchases (over 1000 meters) can enjoy a 3%-5% discount. Due to differences in transportation costs and dealer channels in different regions, there is a 5%-10% regional price difference. For example, the price in coastal industrial concentration areas is slightly lower than that in inland areas.​ The applicable scenarios are closely related to price adaptability. The 16mm² cable is affordable and suitable for residential distribution branches and small equipment power supply, such as household central air conditioners and wall-mounted charging piles; the 25mm² cable has outstanding cost performance and is often used in office building floor trunks and shopping mall lighting systems; 35mm² and 50mm² cables have high prices due to large current-carrying capacity (about 200A and 280A respectively) and strong protection, and are suitable for heavy-load scenarios such as industrial production lines, substation outgoing lines, and underground pipe corridors. Among them, 50mm² cables can meet the continuous power supply needs of large motors and precision instruments. The armoured structure enables the whole series of cables to be directly buried, piped or openly laid in environments with humidity, dust, and mechanical collision risks, reducing additional protection costs and indirectly improving cost performance.​ Market supply and demand have a significant impact on short-term prices. During the peak season (March-October each year), due to the surge in demand for construction and industrial expansion, prices may rise by 5%-10%; during the off-season (November-February), there may be a 1%-3% downward adjustment. In addition, stricter environmental protection policies have limited the production capacity of small manufacturers. Leading enterprises, relying on the advantage of compliant production capacity, have higher price stability. Although the unit price is 10%-15% higher than that of small factories, the quality guarantee (usually 5 years) and after-sales response are more reliable. The price of imported brands (such as a European brand) is 1.5-2 times that of domestic products, mainly due to brand premium and special certifications (such as UL, CE), which are suitable for export projects with strict requirements on international standards.​ In summary, the price system of 50mm², 35mm², 25mm², 16mm² 4-core armoured copper conductor XLPE insulated cables is deeply bound to their performance, specifications, and market factors. Users need to choose suitable specifications based on actual load, laying environment, and budget - for small and medium load scenarios, priority should be given to 16mm² and 25mm² to control costs; for heavy-load or high-risk environments, 35mm² and 50mm² are needed to ensure safety. At the same time, attention should be paid to copper price trends and procurement timing to balance cost performance and reliability.
