This underground cable adopts a 3X25+1X16mm² specification design, suitable for 0.6/1kv voltage level, and is a reliable choice for underground power distribution scenarios.​ Three 25mm² main cores are responsible for three-phase power transmission, and one 16mm² auxiliary core serves as a ground wire, forming a complete power distribution circuit. The current-carrying capacity of the main cores is suitable for small and medium-sized power consumption scenarios, such as underground power distribution main lines in residential communities and power supply for equipment in small industrial parks. The ground wire ensures electrical safety through reliable grounding and quickly conducts current away in case of electric leakage.​ The XLPE insulation layer is one of the core advantages. It has strong temperature resistance and stable insulation performance, and can resist the impact of underground humidity, soil corrosion and other environmental factors. Even in the underground environment with temperature changes or slight chemical erosion, it can still maintain insulation integrity and extend the service life.​ The cable is specially designed for underground laying, with a compact structure and certain mechanical strength, which can withstand soil pressure and slight external impact. During production, the thickness of the insulation layer and the purity of the conductor are strictly controlled to ensure stable operation in scenarios such as underground power distribution and equipment grounding, providing safety guarantee for power transmission.

The Cwcz-a/Cwcz-U-0.6/1kV 1×250mm² power cable is a single-core high-voltage transmission cable designed in strict accordance with the British BS 6387 standard. It is specially developed for high-load scenarios in industrial and infrastructure fields, featuring excellent safety performance and environmental adaptability. With a rated voltage of 0.6/1kV, it is suitable for main lines in medium and low-voltage distribution systems or power supply for large-scale equipment, particularly excelling in environments with strict requirements for flame resistance, temperature resistance, and mechanical strength.​ In terms of specifications, the cable adopts a single-core structure (1×250mm²) with a conductor cross-sectional area of 250mm², capable of carrying extremely large currents. Its rated current-carrying capacity (when laid in air) reaches up to 420A, meeting the power transmission needs of high-power equipment such as large industrial motors, substation outgoing lines, and high-rise building distribution trunks. The conductor is made of high-purity electrolytic copper (purity ≥99.95%), processed through a compact stranding process, which not only reduces DC resistance (≤0.074Ω/km at 20℃) and minimizes transmission loss but also enhances the mechanical strength and flexibility of the conductor, facilitating laying operations in complex scenarios.​ As a cable compliant with BS 6387, its core advantage lies in its stringent safety performance. This standard clearly specifies requirements for the cable's flame resistance rating, temperature range, and mechanical durability. The Cwcz-a/Cwcz-U series meets these requirements through a three-layer protective structure: The insulation layer is made of cross-linked polyethylene (XLPE) with a temperature resistance of 105℃, boasting excellent electrical insulation performance and anti-aging capabilities, enabling stable operation in a wide temperature range from -40℃ to 90℃. The sheath layer is made of flame-retardant polyvinyl chloride (PVC) or low-smoke halogen-free materials, passing the C, W, and Z-class flame resistance tests of BS 6387 — "Class C" indicates it can withstand vertical burning tests for single cables, "Class W" verifies its ability to maintain flame resistance in water, and "Class Z" ensures it can maintain circuit integrity at high fire temperatures (950℃-1000℃) for at least 3 hours, buying valuable time for emergency power supply. In addition, the outer layer of the cable can be equipped with steel tape armoring as needed to enhance resistance to mechanical impact and corrosion, adapting to various laying methods such as underground, pipe conduit installation，and overhead.​ In terms of application scenarios, the cable is widely used in subways, airports, data centers, large shopping malls, and other places with extremely high fire safety requirements. For example, emergency power supply lines in subway tunnels need to meet flame resistance, waterproofing, and vibration resistance requirements simultaneously, and the W-class flame resistance and armoring design of Cwcz-a/Cwcz-U cables can perfectly adapt to this. The main distribution lines of data centers carry the power supply tasks of massive servers, and their high current-carrying capacity and low loss characteristics can ensure the continuous and stable operation of the system. Moreover, the low-smoke halogen-free sheath can reduce the release of toxic gases in case of fire, minimizing harm to equipment and personnel.​ In the production process, the cable follows the quality control procedures of BS 6387 throughout, with conductor stranding, insulation extrusion, and sheath forming all using automated equipment to ensure dimensional accuracy and performance consistency. Finished products undergo multiple rigorous tests, including power frequency withstand voltage test (3kV/5min without breakdown), partial discharge test (≤10pC), and flame resistance test. Each batch of products is accompanied by a test report to ensure compliance with international safety standards.​ In summary, the Cwcz-a/Cwcz-U-0.6/1kV 1×250mm² power cable, with its ultra-high current-carrying capacity, safety performance certified by BS 6387, and wide environmental adaptability, has become an ideal choice for high-load, high-safety-level distribution scenarios, providing a solid guarantee for power transmission in critical facilities.

The Na2xy-J 4×95mm², 4×50mm² 0.6/1kv XLPE insulated cable is a high-performance cable suitable for medium and low-voltage power distribution systems. With the excellent properties of XLPE insulation material and multi-specification cross-sectional design, it is widely used in power transmission in industrial plants, commercial buildings, municipal engineering and other scenarios, providing stable and safe energy guarantee for complex electrical environments.​ In terms of structural design, both cables adopt a 4-core copper conductor configuration, corresponding to cross-sectional specifications of 95mm² and 50mm² respectively. The conductors are made of high-purity electrolytic copper (purity ≥99.95%) through a bunch stranding process, which not only improves the mechanical strength of the conductor, enabling it to withstand tensile and bending stresses during laying, but also reduces the skin effect loss during current transmission, with a conductivity of over 58MS/m. In the 4-core design, 3 cores are phase lines and 1 core is a neutral line, adapting to the three-phase four-wire power distribution system without the need for additional neutral line laying, simplifying the wiring process.​ The insulation layer is the core advantage of this series of cables, using cross-linked polyethylene (XLPE) material. The thickness of the insulation layer is designed differently according to the cross-sectional specifications: 1.4mm-1.8mm for 4×95mm² cables and 1.2mm-1.5mm for 4×50mm² cables. After cross-linking treatment, XLPE forms a three-dimensional network molecular structure, with excellent electrical properties - insulation resistance ≥1000MΩ·km, breakdown strength ≥20kV/mm, and can operate stably for a long time under the rated voltage of 0.6/1kv. At the same time, its temperature resistance is outstanding, with a long-term working temperature of up to 90℃, and can withstand 250℃ high temperature during short circuits (within 5 seconds), far exceeding ordinary PVC insulated cables, suitable for high-temperature environments or short-term overload scenarios.​ The sheath and protection design further enhance the cable's environmental adaptability. The sheath is made of weather-resistant polyvinyl chloride (PVC) material. The sheath thickness of 4×95mm² cables is 1.8mm-2.2mm, and that of 4×50mm² is 1.5mm-1.8mm, with good acid and alkali resistance, UV resistance and wear resistance, which can resist oil pollution, chemical corrosion in industrial environments and climate erosion during outdoor laying. In addition, the cable as a whole has undergone bunch flame retardant treatment, with an oxygen index ≥30, meeting the GB/T 18380 flame retardant standard, which can effectively delay the spread of flame and reduce the risk of fire.​ In terms of performance parameters, both cables meet the 0.6/1kv voltage level requirements, with significant differences in current-carrying capacity: the 4×95mm² cable has a current-carrying capacity of about 240A-260A when laid in air and 200A-220A when directly buried, suitable for power supply of high-power equipment clusters; the 4×50mm² has a current-carrying capacity of about 150A-170A in air and 120A-140A when directly buried, suitable for medium-power load scenarios. The bending radii are 12 times and 10 times the cable outer diameter (about 280mm and 200mm respectively), facilitating laying in narrow spaces.​ In application scenarios, 4×95mm² cables are often used in power trunk lines of production lines in industrial plants and power supply of central air conditioning systems in commercial complexes; 4×50mm² are suitable for distribution branches in office buildings, municipal street lamp systems, etc. Both support various laying methods such as open laying, pipe threading and direct burial, and can maintain stable performance in complex environments such as humidity, dust and high temperature, with a designed service life of more than 30 years.​ In terms of construction and maintenance, excessive bending or extrusion should be avoided during cable laying. For direct burial, a sand cushion should be laid and warning signs should be set; special cold-shrink or heat-shrink accessories are used for sealing at joints to ensure waterproof and moisture-proof. In daily maintenance, the operating temperature can be monitored by infrared temperature measurement, and the aging degree can be evaluated in combination with insulation resistance testing to early warn potential faults.​ In summary, the Na2xy-J series XLPE insulated cables, with their characteristics of high-efficiency conductivity, temperature and corrosion resistance, flame retardancy and safety, have become an ideal choice in the medium and low-voltage power distribution field, providing reliable support for power transmission in various construction and industrial scenarios.
