Overhead Insulated Power Cable Aluminium Alloy Cable Overhead Cable
Our overhead insulated power cables and aluminium alloy overhead cables are engineered for reliable outdoor power transmission and distribution, designed to replace traditional bare conductors in urban, suburban, and rural areas. Combining high-strength aluminium alloy conductors with durable insulation materials, these cables deliver exceptional safety, weather resistance, and long-term performance—perfect for utility grids, industrial plants, and rural electrification projects where stability and cost-effectiveness matter most. Unlike generic cables, our products are manufactured to meet international standards, ensuring consistent performance in harsh outdoor conditions and reducing maintenance costs for years to come.
Key Products & Core Features
1. Overhead Insulated Power Cable
Insulation Material: High-quality XLPE (Cross-Linked Polyethylene) or HDPE, featuring excellent UV stability, moisture resistance, and abrasion resistance—capable of withstanding long-term exposure to sun, rain, and extreme temperatures (-40℃ to 50℃) without degradation.
Conductor: Stranded aluminium alloy (AAAC) for optimal conductivity and mechanical strength, balancing lightweight design with low power loss. The stranded structure enhances flexibility, making installation easier even in tight spaces or over long spans.
Safety Advantage: Fully insulated design eliminates the risk of short circuits caused by tree contact, foreign objects, or accidental human/animal contact—reducing power outages and safety hazards compared to bare conductors. Ideal for densely populated areas and forested regions where safety clearances are limited.
Voltage Range: 1KV, 10KV, 35KV (low to medium voltage), suitable for secondary power distribution and service drops from utility poles to residential, commercial, or industrial buildings.
2. Aluminium Alloy Overhead Cable (AAAC)
Material Superiority: Heat-treatable magnesium-silicon aluminium alloy, offering 300% better creep resistance than pure aluminium—preventing cold flow and relaxation under heat and pressure. It also boasts higher tensile strength and 30% elongation, ensuring safe operation even over large spans (up to 4000 meters self-weight bearing).
Electrical Performance: Resistivity of 0.0326 ohms·mm²/m at 20℃, with a temperature coefficient of 0.00360/℃—delivering efficient current transmission with minimal power loss. Conductivity is 61.5% of copper IACS, while current-carrying capacity reaches 79% of copper, making it a cost-effective alternative to copper cables.
Environmental Adaptability: Excellent corrosion resistance, thanks to a natural oxide layer that protects against salt spray, humidity, and industrial pollutants—ideal for coastal areas, chemical parks, and railway tunnels. It also withstands wind pressure (80–130 kg/m²) and seismic acceleration (0.05–0.12g).
Application Flexibility: Suitable for overhead power transmission lines across rivers, valleys, and remote rural areas. Its lightweight design reduces tower and support costs, while easy installation and maintenance save time and labor during project deployment.

Applications
Our overhead cables are versatile and widely used in various power transmission and distribution scenarios, including:
Urban Power Distribution: Perfect for densely populated cities, where safety and space-saving are priorities. The insulated design reduces the need for large clearances, making it suitable for narrow corridors and residential areas.
Rural Electrification: Ideal for long-distance power transmission in remote rural areas, where low maintenance and cost-effectiveness are key. The aluminium alloy’s lightweight design simplifies installation over valleys, rivers, and open fields.
Industrial & Commercial Use: Suitable for industrial plants, chemical parks, and commercial complexes that require stable, reliable power supply. The corrosion-resistant and durable design ensures minimal downtime and long service life.
Temporary Power Supply: Deployable for construction sites, temporary events, and emergency power needs—easy to install and remove, while maintaining safety standards in outdoor environments.
Why Choose Our Cables?
Cost-Effective: Aluminium alloy is lighter and more affordable than copper, reducing material, transportation, and installation costs—without compromising performance. It also lowers long-term maintenance expenses by minimizing outages and replacements.
Durable & Reliable: Manufactured with high-quality materials and strict quality control, our cables resist UV radiation, moisture, corrosion, and mechanical damage—ensuring a service life of 20+ years in harsh outdoor conditions.
Easy Installation: Lightweight and flexible design simplifies handling and installation, even over long spans. The self-supporting structure reduces sag, eliminating the need for additional support materials in many cases.
Customizable: We offer custom specifications (nominal area, stranding, voltage rating, insulation type) to meet your specific project needs—whether for small-scale residential service drops or large-scale rural electrification projects.
