The YJV32 is a widely used medium-voltage (MV) steel-tape armored power cable featuring high-purity copper conductors, cross-linked polyethylene (XLPE) insulation, and a steel-tape armor structure. Designed to meet stringent industrial power transmission standards, this cable provides stable power delivery in complex outdoor, underground, and harsh field conditions. Combining superior mechanical protection, electrical performance, and environmental adaptability, it is an ideal cabling solution for large-scale infrastructure, industrial parks, municipal power grids, and commercial complex projects worldwide. Unlike traditional unarmored medium-voltage cables, its built-in steel-tape armor significantly enhances the cable's resistance to external mechanical damage, making it suitable for direct burial and long-term operation in harsh engineering environments.

This series of medium-voltage cables covers a full range of standard specifications to meet various engineering design needs. The conductor uses highly conductive solid/stranded electrolytic copper to ensure low resistance and high conductivity. The rated voltage range covers mainstream medium-voltage levels for industrial and municipal applications, fully complying with international and regional electrical standards.

The XLPE insulation layer has uniform thickness and excellent dielectric strength, effectively preventing leakage, partial discharge, and insulation aging during long-term operation. The outer steel tape armor provides strong resistance to compression, torsion, and puncture. The outer sheath is made of high-density polyolefin material, offering excellent waterproof, corrosion-resistant, and weather-resistant properties. All raw materials undergo rigorous screening, and finished products undergo multiple rounds of factory testing, including electrical performance, mechanical strength, and aging resistance tests, to ensure consistent quality across batches.

The conductor cross-sectional area covers the full range of standard sizes to meet the different load current requirements of main lines and branch circuits. The overall structure is compact, with a reasonable interlayer layout, and optimized cable bending performance, facilitating on-site transportation, laying, and construction.

The cross-linked polyethylene insulation layer endows the cable with ultra-low dielectric loss and stable electrical performance under continuous high load operation. Even under long-term energized operation, it maintains reliable insulation performance, effectively preventing insulation breakdown and electrical faults. The high-purity copper conductor has excellent conductivity, reducing power loss during transmission and helping project operators reduce long-term energy consumption. Furthermore, the cable has strong electromagnetic interference resistance, ensuring stable power supply without interfering with nearby control circuits, communication lines, and precision electrical equipment.

The double-layer steel tape armor is a core highlight of the YJV32 cable. It possesses excellent resistance to compression, impact, scratches, and animal bites, which is crucial for cables laid directly underground, along roadsides, or in construction areas where ground activity is frequent. The integrated structure resists deformation under external pressure, and the overall tensile strength meets the requirements for long-distance laying and terrain adaptability. Even in areas with slight ground subsidence or frequent construction activities, the internal core structure is adequately protected, thereby extending the overall service life of the cable system.

The special sheath material is resistant to acids, alkalis, chemical corrosion, and ultraviolet radiation, making it adaptable to various geological environments, including damp soils, saline-alkali lands, and industrial chemical zones. It has a wide operating temperature range, functioning stably in both high-temperature outdoor environments and low-temperature underground environments. The cable has excellent waterproof and moisture-proof properties, effectively preventing groundwater and humid air from penetrating the internal structure, thus ensuring stable operation for decades without premature aging or failure, even in fully buried installations.

Thanks to its optimized structural design, the cable has a moderate bending radius and good flexibility, suitable for common installation methods such as pipe trenches, cable ducts, and direct burial. The wear-resistant and easy-to-peel surface sheath reduces the difficulty of on-site wiring, joint fabrication, and subsequent maintenance. Standardized outer diameter and structural dimensions are compatible with mainstream cable accessories, connectors, and laying tools in the industry, saving construction time and reducing the cost of auxiliary materials for the engineering team.

YJV32 medium-voltage armored cables are designed for medium-distance, high-capacity power transmission projects and are widely used in various industries and engineering fields:

• Municipal Power Grid Projects: Urban trunk lines, community distribution networks, road lighting power supply systems, and municipal public facilities power supply. Direct burial along urban roads is its most typical application scenario, as the armor layer effectively resists external construction damage.
• Industrial Parks and Manufacturing Plants: Main power supply lines for heavy industry, light industry, chemical plants, and manufacturing workshops. Capable of withstanding complex environments such as mechanical vibration, chemical volatiles, and frequent vehicle traffic within factories.
• Infrastructure Construction: Power distribution systems for railway transportation, airport facilities, ports, water conservancy projects, and large transportation hubs. These projects require highly reliable, long-life cables to ensure the continuous operation of critical facilities.
• Commercial and Large Buildings: Providing centralized power supply for shopping malls, office buildings, stadiums, and large residential areas; used for main power input lines and regional distribution lines in large building complexes.
• Remote areas and field projects: Provide power transmission for centralized power conversion projects in field exploration bases, mining areas, and rural areas. It can adapt to harsh geological and climatic conditions in the field and requires very little daily maintenance.

As a core material in power engineering, the correct selection and matching of cables directly determines the overall safety and service life of the power system. We have summarized the following key points for engineering designers, technical engineers, and procurement experts:

• Specification Matching to Load Requirements: First, confirm the actual operating current, transmission distance, and rated voltage of the circuit, and select the appropriate conductor cross-sectional area and voltage rating. Oversized specifications will lead to cost waste, while undersized specifications will lead to overload operation and potential safety hazards.
• Installation Environment Confirmation: For areas with direct burial, roadside laying, heavy vehicle traffic, or frequent construction, YJV32 armored cables are preferred. For environments with strong chemical corrosion or long-term immersion, the sheath rating needs further confirmation to ensure complete environmental adaptability.
• Compliance with Laying Standards: During construction, local electrical engineering standards should be followed. Strictly control the cable bending radius and avoid violent dragging or sharp-angle compression to prevent damage to the armor and sheath. Allow reasonable cable slack to cope with terrain changes and subsequent maintenance.
• Batch Quality Consistency: For large-scale project procurement, suppliers with stable production capacity and a sound quality control system are prioritized. Consistency in product size, material, and performance between batches avoids on-site assembly issues.
