China AAC IEC 61089 All-Aluminum Conductor Suppliers - Factory Direct High Conductivity Power Transmission Solutions

,

Execution Standard: IEC 61089

,

Material: AAC is made from high-quality AL1 aluminum material.

,

Product Application: AAC aluminum stranded conductors are renowned for their excellent electrical conductivity, ensuring efficient power transmission with minimal energy loss. They are an ideal choice for medium and low-voltage distribution networks.

,

AAC (All-Aluminum Conductor) offers a streamlined power transmission solution constructed from premium aluminum to maximize electrical conductivity. Its all-aluminum design eliminates the extra weight associated with steel cores, making it particularly suitable for short-span, low-tension overhead lines. This feature is especially advantageous for urban subnetworks and rural feeder lines where cost-effectiveness and easy maintenance are crucial. As a leading factory in China, we are proud to supply high-performance AAC conductors that meet the demands of modern electrical infrastructure.

    Frequently Asked Questions (FAQ)
    What is the standard lay direction for these AAC conductors?
    According to the technical specifications, the outermost layer of these Aluminum Stranded Conductors (AAC) is twisted to the right, which is designated as a Z-lay configuration.
    How does the number of wires change with the sectional area?
    The wire stranding configuration transitions from 7 wires for smaller sizes (up to 63.2 mm²), to 19 wires (100.1 to 249.6 mm²), 37 wires (314.5 to 560 mm²), 61 wires (631.3 to 1000.6 mm²), and up to 91 wires for the largest conductors (1120.8 to 1499.2 mm²).
    What is the maximum electrical resistance at 20℃ for the smallest AAC size?
    The AAC conductor with a nominal code name of 10 (10.0 mm² sectional area) features a maximum DC resistance of 2.8633 Ω/km at 20℃.
    What is the nominal breaking load range of these conductors?
    The nominal breaking load ranges from 1.95 kN for the smallest size (Code Name 10) up to 240 kN for the largest size (Code Name 1500), reflecting the tensile strength scaling with sectional area.
    How does the linear mass of AAC scale with the conductor size?
    The linear mass starts at 27.4 kg/km for the 10 mm² conductor and increases up to 4160.2 kg/km for the 1499.2 mm² conductor, aligning directly with the volume of aluminum used per kilometer.
