XLPE Insulated Steel Tape Armored PVC Sheathed Low-Voltage Power Cable

XLPE insulated steel tape armored PVC sheathed low-voltage power cable is a mainstream, cost-effective and highly reliable power transmission product specially developed for civil and industrial low-voltage power distribution systems. Adopting high-quality cross-linked polyethylene (XLPE) as the core insulating material, steel tape as the mechanical armor layer and polyvinyl chloride (PVC) as the outer protective sheath, the cable integrates excellent electrical insulation performance, strong mechanical compression and impact resistance, outstanding aging resistance and stable environmental adaptability. Different from ordinary unarmored cables, the built-in steel tape armor structure can effectively resist external mechanical extrusion, rolling, impact and piercing damage during underground burial, pipe laying and long-term operational use, greatly improving the safety and durability of line operation. With standardized manufacturing technology and stable product performance, this series of low-voltage cables has become the most widely used basic wiring product in urban construction, industrial production, municipal engineering and key national infrastructure projects.

Product Application: This series of power cables is applicable to power transmission and distribution in AC 50Hz circuits with a rated voltage of 0.6kV to 1kV, covering almost all conventional low-voltage power supply scenarios for industry, commerce and civil buildings. As the basic carrier of low-voltage power systems, the cable undertakes core functions such as equipment power supply, regional power distribution and circuit energy transmission, and is suitable for fixed laying in cable trenches, underground pipelines, indoor and outdoor wall wiring, tunnel laying and other conventional environments.

In particular, the flame-retardant models of this cable series are tailored for high-standard fire-proof scenarios with dense cable laying and strict safety requirements. They are widely deployed in high-rise buildings, subway transit systems, power generation stations, large industrial and mining enterprises and other key places. In these densely wired environments, ordinary cables are prone to flame spread and secondary disaster expansion in case of fire accidents. The optimized flame-retardant formula of our flame-retardant cables can effectively inhibit flame combustion and spreading, avoid fire propagation along cable lines, greatly reduce fire hazards, and ensure the safety of personnel and equipment in high-risk building and industrial scenarios.

Product Models: This product covers a complete range of mainstream low-voltage cable models, including VV, VLV, VV22, VLV22, YJV, YJLV, YJV22, YJLV22 and customized flame-retardant series. The diversified model portfolio includes copper-core and aluminum-core specifications, armored and non-armored structures, as well as ordinary and flame-retardant types. It can flexibly meet different engineering demands such as load capacity requirements, laying environments, mechanical protection standards and fire protection grades, providing targeted and economical wiring solutions for various low-voltage power distribution projects.

Executive Standard: GB/T12706.1—2020

All products are strictly manufactured, inspected and delivered in accordance with the national standard GB/T12706.1—2020 for rated voltage power cables. This standard uniformly regulates the raw material selection, structural dimensions, manufacturing processes, electrical performance indicators, mechanical properties and factory testing standards of low-voltage power cables. Strict implementation of national specifications ensures that every cable product has stable quality, standardized performance and high safety factor, fully meeting the construction requirements of industrial projects and national key engineering projects.

Operating Characteristics: The product has clear and standardized operating and laying technical indicators to ensure safe and stable long-term operation. The maximum long-term allowable working temperature of the cable conductor shall not exceed 70℃, which adapts to the continuous load operation of conventional low-voltage power distribution lines and avoids insulation aging and performance degradation caused by long-term overheating. Under short-circuit fault conditions with a maximum duration of no more than 5 seconds, the maximum instantaneous temperature of the cable conductor shall not exceed 160℃. This excellent short-term heat resistance effectively prevents insulation breakdown and cable burnout caused by instantaneous short-circuit current, improving the fault tolerance and operation safety of the circuit system.

The ambient temperature for cable laying shall not be lower than 0℃, which avoids the embrittlement and cracking of PVC sheath and XLPE insulation caused by low temperature during construction. The cable has no drop height limitation during laying, featuring strong construction adaptability and simple operation. In addition, the product has the advantages of simple daily maintenance and low later-stage operation cost. In terms of bending construction standards, different structural cables have standardized minimum bending radius requirements: the minimum bending radius of conventional cables is no less than 10 times the cable outer diameter; armored cables need to reach 12 times the outer diameter to protect the internal steel tape armor from deformation and damage; five-core cables with complex structural layout have a stricter standard of 15 times the outer diameter, ensuring that the internal conductor and insulation structure will not be damaged during bending and laying.

Industry Application and Project Strength

Benefiting from stable electrical performance, reliable mechanical protection, excellent fire safety and convenient construction characteristics, our XLPE insulated steel tape armored PVC sheathed low-voltage power cables are widely used in metallurgy, electric power, energy, chemical industry, construction, shipbuilding, transportation and other industrial fields, and have been widely selected for various national key engineering projects.

In the metallurgical industry, the cables are used for low-voltage power distribution of workshop auxiliary equipment, conveying machinery and environmental protection monitoring equipment, adapting to industrial environments with dust and slight mechanical impact. In the electric power and energy industry, they are applied for auxiliary power supply and internal distribution lines of power stations, wind farms and photovoltaic power stations, providing stable basic power guarantee for energy production and operation. In chemical industrial parks, the PVC sheath provides good anti-corrosion and anti-pollution performance, suitable for conventional workshop power supply circuits.

In the construction industry, especially high-rise buildings and large commercial complexes, flame-retardant armored cables are used for main power supply and fire-fighting power distribution lines to ensure building power safety. In subway and transportation infrastructure projects, the cables undertake power supply tasks of tunnel ventilation, monitoring equipment and station auxiliary facilities. In shipbuilding and marine supporting projects, they adapt to onshore dock power distribution and auxiliary equipment wiring needs. Relying on excellent comprehensive performance, the product has become an indispensable basic wiring material for various industrial production and municipal infrastructure construction.
