This product is Freetox Halogen-Free Cable N2xoh Triple 0.6/1kv multipolar cable, including two specifications: 3-1X120 mm² and 3-1X300 mm².​ The cable adopts a triple insulation design with a rated voltage of 0.6/1 kV, suitable for low-voltage power distribution systems. "Freetox Halogen-Free" indicates that it has halogen-free characteristics, which will not release toxic halogenated gases when burned, effectively reducing hazards in fires and improving safety. It is especially suitable for places with high requirements for environmental protection and safety, such as high-rise buildings, hospitals, subways, data centers, etc.​ The 3-1X120 mm² specification is composed of 3 groups of independently insulated wire cores, each with a conductor cross-sectional area of 120 mm². It is suitable for medium-power power transmission and can meet the power supply needs of small and medium-sized equipment clusters; the 3-1X300 mm² specification also includes 3 groups of independently insulated wire cores, with a single group conductor cross-sectional area of 300 mm², which can carry larger currents and is suitable for high-load power distribution scenarios, such as the main distribution trunk of large building complexes and power supply for high-power equipment in industrial plants.​ Both specifications focus on the conductivity of the conductor and the aging resistance and wear resistance of the insulation layer, complying with relevant environmental protection and electrical safety standards, providing safe, stable and environmentally friendly transmission guarantees for power systems in various places.

This paper introduces the Freetox Halogen-Free N2xoh 0.6/1kV 3X120+1X70 multipolar cable, a power transmission cable designed for safety and environmental protection requirements. It features a four-core structure with 3 phase conductors of 120mm² and 1 neutral conductor of 70mm², with a rated voltage of 0.6/1kV, suitable for medium and low-voltage distribution systems.​ "Freetox Halogen-Free" indicates that the cable uses halogen-free materials for its insulation and sheath. When burned, it does not release toxic halogen gases (such as chlorine and bromine) and only produces a small amount of low-toxic smoke, which can effectively reduce casualties and equipment damage in fires, meeting high safety standards. The N2xoh model identifier further reflects its halogen-free properties and specific structural design, with good temperature resistance and mechanical strength.​ The cable conductor is made of high-purity copper, ensuring excellent electrical conductivity and reducing transmission losses. The four-core structure is compatible with three-phase four-wire distribution scenarios, meeting power feeding needs in industrial plants, commercial buildings, public facilities, etc., and is particularly suitable for environments with strict fire safety requirements such as hospitals, schools, and subways.​ With the core advantages of halogen-free environmental protection, safety and reliability, the cable provides stable power transmission while offering additional safety protection for crowded and sensitive areas, making it an ideal distribution solution that balances performance and environmental friendliness.

The Freetox Halogen-Free N2xoh 0.6/1 Kv 3X120+1X70 mm² multipolar cable is an excellent performance, safe and environmentally friendly power transmission cable. With its unique design and excellent characteristics, it plays an important role in various power transmission scenarios.​ In terms of specification parameters, the cable has a multipolar structure. "3X120+1X70 mm²" clearly indicates that it contains 3 main cores with a cross-sectional area of 120mm² and 1 neutral core with a cross-sectional area of 70mm². This structural design enables it to meet the transmission requirements of the three-phase four-wire power system. The main cores are responsible for transmitting electric energy, and the neutral core plays a role in balancing the current and ensuring the stable operation of the system. The rated voltage of the cable is 0.6/1 Kv, which is suitable for low-voltage distribution systems and can be widely used in power transmission in industrial, commercial, civil and other fields. In terms of current-carrying capacity, at an ambient temperature of 25℃, the long-term allowable current-carrying capacity of the 120mm² main core is about 260A, and that of the 70mm² neutral core is about 180A. It can meet the power transmission demand of about 57kW and can be adapted to various medium-power electrical equipment and distribution systems. In addition, the outer diameter of the cable is about 55mm, the insulation thickness of the main core is about 1.8mm, the neutral core is about 1.6mm, and the sheath thickness is about 2.5mm. These parameters ensure that the cable has good insulation performance and mechanical strength, while being able to adapt to different laying environments.​ In terms of materials, the biggest highlight of the cable is the use of halogen-free materials, which meets the Freetox halogen-free standards. The conductor is made of high-purity electrolytic copper with a purity of more than 99.95%, which has excellent conductivity, can effectively reduce the loss in the process of electric energy transmission, and improve the transmission efficiency. At the same time, the pure copper conductor has good ductility and mechanical strength, which is not easy to break during laying and use, ensuring the service life of the cable. The insulation layer is made of halogen-free cross-linked polyethylene (XLPE) material, which not only has excellent insulation performance, high insulation resistance and good corona resistance, can effectively prevent leakage, but also does not release toxic and harmful halogen gases when burned, greatly reducing the harm to personnel and the environment in case of fire. The sheath is made of halogen-free low-smoke polyolefin material, which has good flame retardancy, corrosion resistance and mechanical strength. It can protect the internal core from external mechanical damage, chemical erosion and moisture. At the same time, it emits little smoke when burned, which is conducive to personnel evacuation and fire rescue.​ The cable has a wide range of characteristic uses. In the industrial field, it can be used for distribution trunks in small and medium-sized factories, connecting various production equipment in the workshop, such as machine tools, fans, water pumps, etc., to provide stable power support for them. In commercial buildings, it is suitable for distribution systems in shopping malls, office buildings, hotels and other places, transmitting electricity for lighting, air conditioning, elevators and other equipment. Its halogen-free characteristic can improve the fire safety level of buildings. In terms of civil buildings, it can be used for low-voltage distribution lines in residential quarters, transmitting electricity from the distribution room to each building to ensure the daily electricity use of residents. In addition, in some places with high requirements for environmental protection and safety, such as hospitals, schools, subways, etc., the cable is an ideal choice. The use of halogen-free materials can reduce environmental pollution and potential safety hazards.​ Compared with traditional halogen-containing cables, Freetox halogen-free N2xoh cables have significant advantages. Firstly, they have excellent environmental performance. Halogen-free materials will not cause halogen pollution to the environment during production, use and disposal, which is in line with modern environmental protection concepts. Secondly, the safety performance is outstanding. In case of fire, no toxic gases are released, and the smoke emission is low, which can strive for more escape time for personnel and reduce the risk of casualties. Moreover, its good electrical and mechanical properties ensure the stable operation and long service life of the cable, which can reduce replacement and maintenance costs.​ To sum up, the Freetox Halogen-Free N2xoh 0.6/1 Kv 3X120+1X70 mm² multipolar cable, with its reasonable specification design, environmentally friendly and safe materials, wide application scenarios and outstanding performance advantages, has become a highly competitive product in low-voltage distribution systems, providing a reliable and safe solution for various power transmission needs.
