This product series comprises 0.6/1kV halogen-free flame-retardant (LSZH) copper power cables, with conductor sizes ranging from 16mm² to 240mm² (including 25mm², 35mm², 50mm², 70mm², 95mm², 120mm², 150mm², and 240mm²). Featuring high-purity copper conductors, XLPE insulation, and LSZH sheathing, these cables comply with N2XH standards. They offer excellent electrical performance, high-temperature resistance (90℃), and eco-friendly properties (low smoke & zero halogen), making them ideal for crowded spaces (e.g., subways, hospitals, and commercial buildings).

This product is a U-1000 R2V/Xv/RV Rvfv type copper power cable available in 4×25mm², 4×35mm², 4×70mm² and 4×95mm² configurations, featuring XLPE insulation with excellent electrical performance and heat resistance, suitable for fixed installations in industrial equipment and building power distribution systems.

This product is a single-core (1C) copper (Cu) power cable with double insulation, featuring cross-linked polyethylene (XLPE) insulation and polyvinyl chloride (PVC) sheath. It is available in various cross-sectional specifications, including 70mm², 95mm², 120mm², 150mm², 185mm², 240mm², and 300mm², flexibly adapting to power transmission needs of different load levels.​ The conductor is made of high-purity electrolytic copper, precision-processed to ensure excellent conductivity. Its resistance value is much lower than industry standards, which can minimize Joule heat loss during power transmission and improve energy transfer efficiency. The inner insulation layer uses cross-linked polyethylene (XLPE) material. After special cross-linking treatment, its temperature resistance level reaches 90℃, with a short-term overload tolerance temperature of up to 130℃. Additionally, it has extremely high insulation resistance and minimal dielectric loss, effectively isolating current leakage between the conductor and the outside, ensuring the safety of power transmission. The outer sheath is made of weather-resistant PVC material, which has excellent UV aging resistance, acid and alkali corrosion resistance, and mechanical impact resistance. It can work stably for a long time in complex environments such as humidity, dust, and outdoor exposure, providing comprehensive protection for the internal structure of the cable.​ The series of cables are designed with full consideration of installation convenience, featuring good flexibility that allows a certain degree of bending for laying, reducing construction difficulty. Meanwhile, their flame retardancy meets the GB/T 18380 standard, which can delay the spread of flames in case of fire, buying time for personnel evacuation and equipment rescue. They are widely used in industrial plant power distribution networks, power supply systems of large commercial complexes, urban underground pipe gallery projects, wind farms, and collector lines of photovoltaic power stations. They are suitable for both fixed laying and short-term temporary power supply needs.​ The synergistic effect of the double insulation structure (XLPE inner insulation + PVC outer sheath) enables the cable to have high insulation strength while possessing excellent mechanical protection performance. It solves the problem that traditional cables are prone to aging and damage in complex environments, significantly extending the service life, making it a preferred cable product with both reliability and economy in power engineering.

The IEC 60502-1 compliant copper cross-linked polyethylene (XLPE) insulated polyvinyl chloride (PVC) sheathed galvanized steel tape armoured 0.6/1kV power cable (model N2xby) is a low-voltage power transmission product with high safety and strong adaptability, widely used in industrial plants, municipal engineering, underground pipe networks and other complex environments. Its rated voltage of 0.6/1kV is suitable for AC 50/60Hz low-voltage power grids, meeting the power transmission needs of medium and high-power equipment clusters and underground laying scenarios.​ In terms of specifications, the conductor is made of high-purity electrolytic copper (purity ≥99.95%) through a compact stranding process. The number of cores (N) and cross-sectional specifications (xmm²) can be flexibly combined, commonly ranging from 2×16mm² to 4×240mm². The DC resistance at 20℃ is ≤0.018Ω/km (4×240mm²) to ≤0.988Ω/km (2×16mm²), and the current-carrying capacity (when laid in air) can reach 480A (4×240mm²), ensuring low-loss and efficient power transmission. The insulation layer is made of XLPE material with a temperature resistance of 90℃, with a thickness of 2.0-4.5mm (increasing with the cross-section), a volume resistivity of ≥1×10¹⁴Ω·cm, which can withstand an ambient temperature difference of -40℃ to 90℃, an insulation eccentricity of ≤15%, and a partial discharge amount of ≤10pC.​ The structural design highlights durability: the inner layer is XLPE insulation, the middle layer is wrapped with galvanized steel tape armouring (thickness 0.5-0.8mm), and the outer layer is a PVC sheath (thickness 1.8-2.5mm). The galvanized steel tape armouring increases the cable's mechanical impact resistance by 60%, which can resist soil extrusion and stone collision during underground laying; the PVC sheath has acid and alkali resistance and UV resistance, with a flame spread rate of ≤0.5m/min, passing the IEC 60332-1 flame retardant test.​ Its characteristic applications cover multiple scenarios: in industrial plants, specifications of 4×120mm² and above can be used as main cables for production lines, withstanding equipment vibration and oil pollution; in municipal engineering, the 2×50mm² model is suitable for underground street lamp lines, and the armoured layer prevents rat and ant bites; in underground pipe corridors, the cable can adapt to humid environments, and can resist groundwater erosion when laid with pipes. Taking 4×240mm² as an example, it can support the connection between an 800kVA transformer and the workshop main distribution box, maintaining stable operation under continuous high load.​ The entire production process follows the IEC 60502-1 standard: the conductor is annealed to eliminate stress, the XLPE insulation adopts a three-layer co-extrusion process to ensure uniformity, the armoured layer uses a fully automatic wrapping machine to achieve a steel tape gap of ≤0.5mm, and the sheath extrusion temperature is controlled at 160-180℃ to avoid aging. Finished products must pass more than 20 tests such as power frequency withstand voltage (3kV/5min without breakdown) and armouring adhesion (≥15N/cm), with a complete test report attached to each batch.
