The NH-YJV32 steel wire armored power cable is available in 3×50mm², 3×70mm² and 3×185mm² configurations, featuring copper conductor, XLPE insulation and PVC sheath with rated voltage 0.6/1kV. Its steel wire armor provides exceptional tensile strength (≥4000N) and mechanical protection, compliant with GB/T 12706 standards for harsh environments like construction sites and tunnels. The flame-retardant cable (per GB/T 18380.3) operates from -20℃ to +90℃, suitable for direct burial or conduit installation.

0.6/1kV 4×6mm², 4×10mm², 4×16mm² steel wire armored (SWA) power cables are efficient transmission lines in low-voltage distribution systems, suitable for three-phase four-wire circuits with voltage levels from 0.6kV to 1kV. All three specifications adopt a 4-core design, with core cross-sectional areas of 6mm², 10mm², and 16mm² respectively. They can be flexibly selected according to load requirements to meet the power supply of different power equipment.​ The cable conductors are made of high-purity copper, with excellent conductivity, which can effectively reduce transmission loss. The insulation layer is made of cross-linked polyethylene (XLPE), which has a wide temperature resistance range (-40℃ to 90℃) and stable insulation performance, and can resist the impact of humid, dusty and other environments. The outer armor is galvanized steel wire, forming a solid protective structure, with outstanding resistance to mechanical impact, extrusion and gnawing by rodents, which prolongs the service life of the cable in complex environments.​ This series of cables features flexible installation methods, supporting direct burial, pipe threading or wall-mounted laying. They are widely used in building power distribution, industrial plants, municipal engineering, outdoor lighting and other scenarios, providing safe and reliable power transmission guarantee for low-voltage distribution systems.

This paper introduces a series of underground steel wire armored electric cables, with specifications covering various cross-sectional areas such as 50mm², 35mm², 16mm², and 25mm². Specifically designed for underground environments, these cables feature a steel wire armor layer, which is formed by tightly winding high-strength galvanized steel wires. This structure can effectively resist mechanical impacts, extrusion, and soil corrosion during underground construction, providing solid physical protection for the cables and significantly enhancing their durability in complex underground environments.​ The conductors of the cables are made of high-purity copper, ensuring excellent electrical conductivity, reducing power transmission losses, and meeting the high-efficiency requirements of underground power transmission. The insulation layer is mostly made of anti-aging and moisture-resistant materials (such as cross-linked polyethylene), forming double protection together with the armor layer to adapt to the harsh underground conditions of high humidity and multiple impurities.​ This series of cables is widely used in underground power transmission networks, municipal engineering underground pipelines, industrial park underground power distribution systems and other scenarios. They are particularly suitable for power laying in areas vulnerable to external interference, such as those needing to cross roads, railways, and rivers. Their diverse specifications can flexibly match the power transmission needs of different powers, providing stable and reliable power transmission support from branch distribution to main lines. They are key equipment with both safety and practicality in underground power engineering.
