Underground Direct Burial Industrial & Municipal Distribution Aluminum Power Cable

The YJLHV22 is a steel-tape armored low-voltage aluminum alloy power cable designed for harsh laying environments, suitable for applications requiring mechanical protection and direct underground burial. It has a rated voltage of 0.6/1kV and utilizes high-quality AA8000 series aluminum alloy tightly stranded conductors, high-performance XLPE cross-linked polyethylene insulation, a steel tape armor layer, and a weather-resistant PVC outer sheath.

As an upgraded armored version of the YJLHV cable, the YJLHV22 adds a robust steel tape armor layer between the insulation layer and the outer sheath, providing excellent resistance to external compression, impact, ground pressure, and geological settlement stress. The optimized aluminum alloy conductor solves the structural creep and poor contact problems of traditional ordinary aluminum cables, maintaining stable conductivity and mechanical toughness during long-term continuous operation.

This cable combines lightweight alloy conductors, excellent insulation performance, and reliable mechanical protection, making it widely used in underground installations, buried pipelines, corrosive industrial environments, and concealed municipal power distribution. It is highly favored by electrical engineers, project procurement managers, and EPC construction companies worldwide. With its standardized manufacturing process and full compliance with international standards, the YJLHV22 is a cost-effective and highly reliable solution that meets the stringent environmental and mechanical protection requirements of modern low-voltage power transmission projects.

Engineer and Procurement Core Selection and Laying Guidelines

• Select conductor cross-section based on actual load current, transmission distance, and allowable voltage drop; aluminum alloy conductors offer better creep resistance than conventional aluminum conductors.
• Steel tape armored structures are specifically designed for direct burial, effectively withstanding soil pressure, ground settlement, and external heavy loads.
• In coastal, humid, and mildly corrosive areas, integrated armored sheath structures reduce external environmental erosion and extend service life.
• During construction, avoid excessive bending and sharp-angle folds; adhere to standard bending radius requirements to protect the integrity of the armor and insulation.
• Aluminum alloy conductors must use dedicated transition joints when terminally connecting to maintain a stable contact over the long term.
• When burying multiple cables side-by-side, maintain standard spacing to facilitate heat dissipation and avoid dense laying that can lead to long-term temperature rise.
• During transportation and storage, keep in a dry, well-ventilated area, protecting the sheath from moisture, mechanical impact, and prolonged direct sunlight.
• For projects with long-term operational requirements, the YJLHV22 armored vehicle should be given priority to reduce the frequency of later maintenance and overall life cycle investment.

Unique Core Product Advantages

• High-Quality AA8000 Alloy Conductor

  Utilizing an optimized AA8000 aluminum alloy formula, it features low creep deformation, high tensile strength, and stable conductivity. This avoids the structural loosening problems commonly found in ordinary aluminum cables under long-term load operation.

• Integrated Steel Tape Armor Protection

  Built-in double-layer steel tape armor effectively resists external impacts, soil pressure, rock crushing, and damage from construction machinery, making it perfect for direct burial scenarios where additional conduit protection is not required.

• High-Performance XLPE Insulation Layer

  The XLPE insulation layer features low dielectric loss, excellent thermal stability, and anti-aging properties, maintaining stable insulation performance even under long-term temperature variations and continuous load operation.

• Durable and Weather-Resistant Outer Sheath

  The PVC outer sheath offers excellent abrasion resistance, ozone resistance, and environmental aging resistance, adapting to complex outdoor, underground, and semi-corrosive working environments.

• Lightweight and Cost-Effective

  Compared to copper-armored cables, YJLHV22 is lighter, resulting in lower transportation and installation costs, making it a more economical choice for large-scale projects while ensuring operational reliability.
