Jklgyj: Integrates XLPE insulation with a galvanized steel reinforcement layer. This addition boosts mechanical strength, making it ideal for areas with high wind loads, ice accumulation, or frequent vibrations—such as coastal regions or industrial zones with heavy machinery.

Jklhyj: Equipped with hydrophobic XLPE insulation, which repels moisture and prevents water ingress. This variant excels in humid climates, rainy regions, or areas prone to condensation, ensuring long-term insulation integrity.

Electrical Conductivity: Aluminum provides high conductivity, ensuring efficient power transmission with minimal loss at 10kv. While copper offers slightly higher conductivity, aluminum’s lower density means the 70mm² conductor achieves comparable performance at a fraction of the weight and cost—critical for overhead installations where weight impacts structural stress.

Mechanical Strength: The conductor undergoes work hardening during manufacturing, enhancing tensile strength and resistance to deformation. This allows it to withstand the tension of overhead installation, wind-induced vibrations, and thermal expansion/contraction without sagging or breaking.

Corrosion Resistance: Aluminum naturally forms a protective oxide layer, which is further enhanced by a specialized anti-corrosive coating. This dual protection shields the conductor from moisture, salt spray, industrial pollutants, and acidic rain, ensuring longevity in diverse environments.

XLPE (Jklyj): Cross-linked polyethylene insulation offers exceptional dielectric strength, enabling safe operation at 10kv. Its cross-linked molecular structure provides thermal stability (-40°C to 90°C), UV resistance, and resistance to chemicals, making it suitable for most urban and rural applications.

XLPE with Galvanized Steel (Jklgyj): The galvanized steel layer is bonded to the XLPE insulation, adding tensile strength and impact resistance. Galvanized steel’s corrosion resistance ensures the reinforcement remains effective even in harsh environments, while its Flexibility allows for easy installation.

Hydrophobic XLPE (Jklhyj): The insulation is treated with a hydrophobic additive that creates a water-repellent surface. This prevents moisture absorption, reduces the risk of water treeing (a common cause of insulation failure), and maintains dielectric strength in wet conditions.

Reduced Wind Resistance: The streamlined profile minimizes wind load, reducing stress on supporting structures and lowering the risk of vibration-induced fatigue—especially critical for Jklgyj in high-wind areas.

Simplified Installation: The bundled design eliminates the need for separate conductors, reducing the number of components to handle and install. This speeds up deployment, lowers labor costs, and reduces the risk of installation errors.

EMI Reduction: The compact configuration minimizes electromagnetic interference (EMI), preventing disruptions to nearby communication lines or sensitive equipment—vital for urban areas with dense infrastructure.

Low Transmission Losses: The combination of high-conductivity aluminum and low-loss insulation ensures minimal power dissipation, maximizing efficiency in 10kv networks. This reduces energy waste and lowers operational costs for utilities.

Voltage Stability: The cables maintain stable voltage levels across long spans, preventing drops that could damage industrial equipment or sensitive electronics. This is particularly important for connecting remote facilities to the main grid.

Short-Circuit Withstand: The conductor and insulation are designed to withstand short-circuit currents for specified durations (typically 1–3 seconds), allowing protective devices to isolate faults before damage occurs. This enhances safety and reduces downtime.

Tensile Strength: Jklyj offers baseline tensile strength for general use, while Jklgyj’s galvanized steel reinforcement increases this by up to 30%, making it suitable for long spans or high-tension installations.

Flexibility: Despite their strength, all cables remain flexible enough to bend around obstacles during installation, such as utility poles or building edges. This flexibility is crucial for adapting to complex urban or rural layouts.

Impact Resistance: The insulation and reinforcement layers (in Jklgyj) protect against impact from debris, hail, or accidental contact during maintenance, preserving conductor integrity.

Temperature Extremes: All variants operate reliably from -40°C (arctic conditions) to 90°C (desert heat), with XLPE insulation maintaining its properties without softening or becoming brittle.

Moisture and Humidity: Jklhyj’s hydrophobic insulation prevents moisture ingress, while Jklyj and Jklgyj’s XLPE resists water absorption, ensuring performance in rain, snow, or coastal fog.

UV and Ozone Resistance: UV stabilizers in the insulation protect against sunlight-induced degradation, while ozone resistance prevents damage in urban or industrial areas with high ozone levels.

Chemical Resistance: The insulation systems resist industrial chemicals, oils, and pollutants, making the cables suitable for installation near factories, refineries, or agricultural zones.

Jklyj: Ideal for general urban Overhead Lines, connecting substations to residential and commercial districts. Its balanced performance suits areas with moderate weather and stable infrastructure.

Jklgyj: Used in urban industrial zones or high-rise areas where wind loads are higher. The galvanized steel reinforcement withstands vibrations from traffic or construction.

Jklhyj: Deployed in humid urban centers or cities with frequent rainfall, preventing moisture-related insulation issues in dense infrastructure.

ANSI/ICEA S-94-649: Certified for North American markets, confirming performance in extreme temperatures and environmental conditions.

Handling: Cables should be stored in dry, covered areas to prevent moisture damage. During transport, avoid kinking or crushing to protect insulation and conductors.

Tensioning: Follow manufacturer guidelines for tension (varies by variant: Jklyj ~8kN, Jklgyj ~10kN) to avoid overstretching. Use tension meters to ensure precise installation.

Bend Radius: Maintain a minimum bend radius (15× cable diameter) to prevent insulation cracking, especially critical for Jklgyj’s reinforced structure.

Support Structures: Use corrosion-resistant brackets and poles rated for the cable’s weight and tension, with extra reinforcement for Jklgyj in high-stress areas.

Visual Inspections: Quarterly checks for insulation damage, conductor corrosion (if exposed), and loose hardware. Focus on Jklhyj in humid areas for signs of moisture ingress.

Thermal Imaging: Annual scans to detect hotspots, indicating potential conductor degradation or poor connections.
