4c × 95mm², 70mm² XLPE SWA flame retardant armored electric power cable is a high-performance transmission line suitable for 600V low-voltage systems. It adopts a 4-core design, with core cross-sectional areas of 95mm² and 70mm², which can be flexibly matched according to load requirements to meet the power supply of different power equipment.​ The cable conductor is made of high-purity electrolytic copper, with high conductivity, which can effectively reduce transmission loss; the insulation layer is made of cross-linked polyethylene (XLPE), with a wide temperature resistance range (-40℃ to 90℃), stable insulation performance, and excellent anti-aging and chemical corrosion resistance. The outer layer integrates steel wire armoring (SWA) and flame retardant layer. The steel wire armoring provides strong mechanical protection against impact, extrusion and gnawing by rodents; the flame retardant property can delay the spread of flame, ensure the circuit to operate normally for a short time in fire environment, and improve safety.​ The cable features flexible installation methods, supporting direct burial, pipe threading or overhead laying. It is widely used in low-voltage distribution systems of high-rise buildings, subways, shopping malls and other crowded places as well as industrial plants, providing a power transmission solution with safety, efficiency and flame retardant protection for key facilities.

Low voltage copper flame retardant and fire resistant power cables (with specifications covering 100, 150, 250, 300, 350 Mcm) are power transmission products designed for high safety demand scenarios. Integrating excellent conductivity, flame retardancy, and fire resistance, they are widely used in high-rise buildings, hospitals, data centers, subways, and other fields with strict fire safety requirements. Their rated voltage is usually 0.6/1kV, suitable for AC 50Hz/60Hz low-voltage power grids, and can meet the power transmission needs of high-power equipment clusters and main distribution lines.​ In terms of specifications, this series of cables uses copper as the conductor core with a purity of ≥99.95%, and the structure stability and conductivity efficiency are improved through compact stranding technology. The cross-sectional specifications from 100 Mcm (about 50mm²) to 350 Mcm (about 178mm²) cover different current-carrying capacity requirements: 100 Mcm has a current-carrying capacity of about 190A, suitable for medium-sized motor power supply; 350 Mcm can reach 420A, which can be used as the main distribution line of large buildings. The DC resistance of the conductor at 20℃ is ≤0.383Ω/km (100 Mcm) to ≤0.108Ω/km (350 Mcm), ensuring low-loss power transmission.​ Flame retardancy and fire resistance are its core advantages. The cable passes the flame retardant test of GB/T 19666 or IEC 60332 standards, using low smoke zero halogen (LSZH) flame retardant polyolefin sheath. The flame spread speed is ≤0.5m/min, and when burning, it has low smoke emission (light transmittance ≥60%) and no toxic gas release. The fire resistance meets GB/T 19216.21 or IEC 60331 standards, and can maintain circuit integrity for more than 3 hours in 950℃-1000℃ flames, ensuring emergency power supply in case of fire.​ The insulation layer is made of cross-linked polyethylene (XLPE) with a temperature resistance of 90℃, formed by three-layer co-extrusion technology. The insulation thickness is 2.0mm-4.5mm (increasing with specifications), and the volume resistivity is ≥1×10¹⁴Ω·cm, which can withstand environmental temperature differences from -40℃ to 90℃. Some models are added with steel tape armoring on the outer layer, which increases the mechanical impact resistance by 40%, suitable for complex laying scenarios such as underground and pipe threading.​ In application scenarios, 100-150 Mcm cables are often used in branch lines of hospital wards and office building strong electric wells; 250-350 Mcm cables are suitable for data center room main trunks, subway tunnel emergency circuits, etc. Taking 350 Mcm cables as an example, they can support the linked power supply of large diesel generators above 500kW and emergency lighting systems, providing key power support for personnel evacuation and equipment rescue in fires.​ During production, each batch of cables must pass more than 20 tests such as power frequency withstand voltage (3kV/5min without breakdown), partial discharge (≤10pC), and fire resistance combustion. The packaging adopts double-layer protection of steel reels and moisture-proof films, supporting sea, land, and air combined transportation. It can provide 1-5 meters of free samples and lifelong technical consulting services to fully ensure project safety and stable operation.

This product is a 3-core and 4-core armored power cable specially designed for industrial and mining scenarios. The core conductor is made of high-purity copper wire, the insulation layer is made of XLPE (cross-linked polyethylene) material, the outer layer is equipped with a steel wire armored structure, and the conductor cross-sectional area covers specifications from 16mm² to 400mm². It is also compatible with solar power supply systems, featuring strong weather resistance, high mechanical strength and stable electrical conductivity. It can meet the power transmission needs under high voltage, high load and harsh environments in industrial production, mining and solar power generation systems.​ In terms of core structure and material selection, the conductor is made of high-purity electrolytic copper (copper content ≥99.95%) through a multi-strand stranding process. This not only improves the flexibility of the conductor, facilitating wiring in complex scenarios, but also effectively reduces the skin effect and proximity effect during current transmission, minimizing power loss. The cross-sectional area range of 16mm² to 400mm² accurately matches different power requirements: the 16mm²-70mm² specification is suitable for the connection between solar photovoltaic panel strings and the power supply of small mining equipment (such as small ventilators and lighting systems); the 120mm²-240mm² specification can meet the power transmission of medium-sized motors in industrial workshops and from solar inverters to distribution cabinets; the large 250mm²-400mm² specification is suitable for large mining equipment in mines (such as roadheaders and crushers), the outgoing lines of industrial high-voltage distribution cabinets, and the main transmission lines from the centralized combiner box of solar power stations to the step-up station. It can stably carry high-load currents and avoid the risk of overheating due to overload.​ The insulation layer is made of XLPE material, which forms a three-dimensional network molecular structure after cross-linking treatment. Compared with traditional PVC insulation, it has better temperature resistance (long-term operating temperature from -40℃ to 90℃, and maximum short-circuit tolerance of 250℃), aging resistance and insulation strength. It can resist oil pollution, chemical corrosion in industrial environments, and moisture and dust erosion in underground mines. At the same time, in outdoor solar applications, it can effectively resist ultraviolet radiation and extend the service life of the cable. The outer steel wire armor is made of hot-dip galvanized high-carbon steel wire, processed by spiral winding or interlocking armoring technology. It can not only resist mechanical impact, extrusion and rock friction in underground mines, but also prevent damage to the cable caused by heavy object collision in industrial scenarios. In addition, the armor layer also has a certain ability to resist rodent and ant bites, further ensuring the operational safety of the cable in complex environments.​ In terms of scenario adaptability, for the industrial field, this cable can be used for power supply of power equipment in factory workshops, connection lines of high-voltage motors, and main transmission between workshops and factory distribution rooms, especially suitable for heavy industrial scenarios with mechanical vibration and oil pollution. In the mining field, whether it is the power supply of underground excavation faces, mining working faces, or the power transmission of above-ground mineral processing plants, its steel wire armored structure and XLPE insulation layer can easily cope with problems such as underground moisture, dust, roof collapse risks and ore friction, ensuring the continuous and stable operation of the mine power supply system. In the solar field, this cable can be used as the string cable of photovoltaic power stations, the connection cable between inverters and combiner boxes, and the transmission cable from power stations to the power grid. The weather resistance and UV resistance of the XLPE insulation layer are suitable for long-term outdoor exposure and alternating high and low temperature environments. The cross-sectional area of 16mm²-400mm² can meet the current transmission needs of photovoltaic power stations of different scales. At the same time, the steel wire armor can protect the cable from mechanical damage during power station construction and operation and maintenance.​ In addition, the product strictly complies with GB/T 12706 (domestic standard) and IEC 60502 (international standard). During the production process, multiple quality control links are carried out, including conductor resistance testing, insulation withstand voltage testing, armor layer adhesion testing, and aging resistance testing, to ensure that each batch of products meets the safety standards of industrial and mining scenarios. At the same time, the cable supports customization of length, armored steel wire diameter and sheath color according to customer needs, further improving the adaptability of the product in different scenarios and providing reliable hardware support for stable power supply in industrial, mining and solar fields.
