APPLICAZIONE
AAAC (Tutto il conduttore in lega di alluminio) sono progettati per la trasmissione affidabile della potenza aerea e la distribuzione in basso & reti elettriche di media tensione, con un eccezionale rapporto resistenza/peso e una resistenza alla corrosione superiore. Sono ampiamente utilizzati in:
- Urban and rural power grid renovation and overhead line expansion projects
- Coastal and high-corrosion industrial area power distribution networks
- Long-span overhead transmission lines for solar & wind farm grid connection
- Rural electrification projects and secondary distribution lines
- Hilly, mountainous and high-tension overhead line installations
These conductors can be installed on overhead transmission towers, utility poles, and long-span structures, with outstanding resistance to atmospheric corrosion, mechanical fatigue, and environmental aging, delivering a longer service life than traditional AAC conductors in harsh operating environments.
COSTRUZIONE
- Conduttore: High-strength heat-treated aluminum-magnesium-silicon alloy (Al-Mg-Si 6201-T81), Classe 2 concentric stranded per IEC standards
- Stranding Structure: Concentric lay stranded construction, uniform lay length for consistent mechanical and electrical performance
- Surface Finish: Smooth, oxide-free surface for optimal electrical contact and enhanced corrosion resistance
- Permanent Marking: Continuous length marking, alloy grade, size and standard compliance printed along the conductor length
CARATTERISTICHE
- Valutazione della tensione: Suitable for LV/MV overhead lines up to 36 kV (customizable for higher voltage transmission networks)
- Valutazione della temperatura:
- Continuous operating: 90°C
- Emergency overload: 120°C (short duration)
- Mechanical Performance: High tensile strength (min. 295 MPa for standard grade), excellent sag control for long-span installations
- Resistenza alla corrosione: Superior atmospheric corrosion resistance, ideal for coastal, industrial pollution, and high-humidity environments
- Electrical Performance: Stable DC resistance per international standards, excellent current-carrying capacity for efficient power distribution
- Weight Advantage: Lower density than steel-reinforced conductors, reduced tower load and lower installation cost for long-span projects
NORME
- ASTM B399: Standard Specification for Concentric-Lay-Stranded Aluminum-Alloy 6201-T81 Conductors for Overhead Electrical Transmission
- CEI 61089: Round wire concentric lay overhead electrical stranded conductors
- BS EN 50182: European standard for round wire concentric lay overhead electrical stranded conductors
- ICEA S-66-524: North American standard for overhead aluminum alloy conductors
- AS/NZS 1531: Australian/New Zealand standard for overhead stranded aluminum alloy conductors
ACSR Conductor Cable
Aluminum Conductor Steel Reinforced - ACSR overhead cables combine high aluminum conductivity with high steel strength, ideal for long-distance, high-voltage, and large-span overhead transmission lines.
Cavo ABC
Cavo ABC (Aerial Bundled Cable) is a compact, overhead insulated power cable widely used for low-voltage power distribution in urban, rural, and residential areas.
ACAR Conductor Cable
ACAR (Conduttore in alluminio, Lega di alluminio rinforzata) i conduttori sono progettati per la trasmissione di potenza aerea ad alta efficienza e la distribuzione in basso & reti di media tensione, combinando l'elevata conduttività dell'alluminio con la resistenza superiore dei nuclei in lega di alluminio per prestazioni ottimali.
