Aster Single Core Cable Insulated Prc 54.6mm2 Stranded Alloy Conductor for Overhead Construction XLPE PVC PE Copper Aluminum

Aluminum Alloy Conductor: This variant offers a compelling strength-to-weight ratio. With a density of 2.7g/cm³, it is 30% lighter than copper, reducing the load on overhead supports (poles, brackets) and extending their service life. Its conductivity of 61% IACS ensures efficient current transfer, with a resistance of 0.34Ω/km at 20°C—ideal for medium-distance transmission.

Copper Alloy Conductor: For applications demanding superior conductivity, the copper variant delivers 98% IACS, minimizing energy loss over long spans. While heavier (8.9g/cm³), its higher tensile strength (25kN for 54.6mm²) makes it suitable for high-stress installations, such as industrial zones with heavy machinery vibrations.

Flexibility: The stranded structure allows the conductor to bend without cracking, simplifying installation around obstacles like utility poles or buildings. This flexibility reduces the risk of damage during handling, a critical advantage in remote construction sites with limited equipment.

Fatigue Resistance: By distributing mechanical stress evenly across strands, the design resists fatigue from wind-induced vibration or thermal expansion/contraction. Testing shows the conductor can withstand 10,000+ vibration cycles (10Hz) without degradation, ensuring longevity in windy regions.

Heat Dissipation: The gaps between strands create air channels that enhance heat dissipation, preventing overheating during high-load periods. This allows the 54.6mm² conductor to maintain its 130A rating even in ambient temperatures up to 40°C.

Temperature Resistance: Operates reliably from -40°C to 90°C, with short-term tolerance up to 130°C during overloads. This makes it ideal for regions with drastic temperature swings, such as desert areas (daytime heat) or cold climates (nighttime frost).

Moisture and Chemical Resistance: XLPE’s cross-linked molecular structure resists water absorption and chemical attack, protecting against insulation breakdown in industrial zones or areas with agricultural runoff.

Abrasion Resistance: Its tough outer layer withstands contact with tree branches, debris, or installation tools, reducing maintenance needs in rugged environments.

UV Stability: Formulated with UV stabilizers, it resists degradation from prolonged sunlight exposure—critical for open overhead installations in sunny regions like the Middle East or Australia.

Flame Retardancy: PVC is inherently flame-retardant, self-extinguishing within 30 seconds of removing the ignition source, enhancing safety in residential areas.

Ease of Processing: PVC is easy to strip and terminate, simplifying on-site installation and reducing labor time by 15% compared to XLPE.

Waterproofing: PE is 100% waterproof, making it the top choice for wetlands, coastal areas, or regions with heavy rainfall (e.g., Southeast Asia’s monsoon zones).

Flexibility at Low Temperatures: Remains flexible at -40°C, avoiding cracking in freezing conditions—unlike PVC, which can become brittle below 0°C.

Chemical Resistance: Resists acids, alkalis, and salt spray, ensuring durability in industrial or coastal applications where corrosion is a concern.

Current-Carrying Capacity: 130A at 40°C ambient temperature for both copper and aluminum variants. Derating factors apply in higher temperatures: 110A at 50°C, 90A at 60°C—ensuring safe operation even in heatwaves.

Voltage Rating: Designed for low to medium voltage (0.6/1kV to 11kV), with insulation thickness calibrated to prevent dielectric breakdown. XLPE-insulated models handle 11kV, while PVC/PE variants are optimized for 0.6/1kV applications.

Short-Circuit Withstand: Can tolerate 20kA for 1 second, with the conductor and insulation remaining intact. This protects against damage during fault conditions, reducing downtime and repair costs.

Voltage Drop: Over a 45-meter span, voltage drop is limited to 3% at full load—well within the 5% maximum allowed by most electrical codes, ensuring end-users receive stable voltage.

Tensile Strength: Aluminum variants offer 18kN breaking strength; copper variants, 25kN. This allows spans of up to 45 meters without intermediate supports, reducing infrastructure costs in rural areas.

Wind Load Resistance: Tested to withstand wind speeds up to 120km/h (Category 1 typhoon), the Stranded Conductor and insulation flex rather than snap, ensuring integrity in storm-prone regions.

Sag Characteristics: At 40°C, maximum sag over 45 meters is 2.1 meters—maintaining safe clearance (3.5 meters) over pedestrian areas. Thermal expansion is minimal (0.02mm/m/°C), reducing sag variations with temperature.

Flexibility: The stranded conductor and flexible insulation allow bending to a radius of 12 times the cable diameter (≈180mm), simplifying routing around obstacles.

Lightweight Handling: Aluminum variants weigh 1.8kg/m, enabling manual installation by a 2-person crew—critical for remote sites without heavy machinery.

Termination: Compatible with standard compression lugs, with insulation that strips cleanly to expose conductors. Anti-oxidant paste (for aluminum) ensures secure, corrosion-free connections.

Rural Electrification: Powers remote villages, where its 45-meter span reduces pole requirements. Aluminum variants are preferred here for cost and weight advantages.

Industrial Feeder Lines: Connects factories to main grids, with copper variants handling high-power machinery. XLPE insulation resists industrial heat and chemicals.

Urban Distribution: Distributes power in suburban areas, with PVC-insulated models standing up to UV exposure in open installations.

Coastal Networks: PE-insulated aluminum variants resist salt spray in coastal regions (e.g., Philippine islands, Caribbean nations), preventing corrosion.

Renewable Energy Links: Connects solar farms or wind turbines to grids, with XLPE handling temperature fluctuations in exposed locations.

IEC 60502: Complies with this international standard, covering conductor dimensions, insulation thickness, and mechanical testing (tensile strength, impact resistance).

Regional Certifications: Certified for use in North America (UL 44), Europe (CE), and Asia (BIS, TIS), with documentation in local languages to streamline project approvals.

Environmental Compliance: RoHS-compliant, containing no lead, cadmium, or mercury, aligning with green construction initiatives.

Inspections: Annual visual checks for insulation damage, conductor corrosion (rare with aluminum’s oxide layer), or excessive sag. In industrial/coastal areas, inspect twice yearly.

Cleaning: Remove debris with a soft brush to prevent insulation abrasion. Avoid high-pressure water, which may damage PE/PVC.

Repairs: Small insulation damage uses heat-shrink sleeves. Severe damage requires section replacement to maintain performance.

End-of-Life: 100% recyclable—aluminum/Copper Conductors and plastic insulation are recovered, supporting circular economy goals.
