从China供应商批量进口Aluminum Alloy Bare Conductor(Aaac)

Zhengzhou Zms Cable Co., Ltd. manufactures aluminum alloy bare conductor (AAAC) for overhead power transmission and distribution networks. The conductor employs aluminum alloy strands rather than pure aluminum, yielding higher tensile strength than equivalent all-aluminum conductors (AAC) while retaining favourable conductivity. Typical alloy compositions include aluminum with magnesium and silicon additions (Al-Mg-Si), heat-treated to achieve mechanical properties specified under IEC 61089 and ASTM B399. The bare construction means no insulating jacket, so installation requires appropriate clearances and tower designs for the rated voltage.

The Al-Mg-Si alloy chemistry provides natural corrosion resistance through a stable oxide film, reducing the need for protective coatings in most environments. Strand counts vary by conductor size, with common constructions ranging from 7-strand for smaller cross-sections to 19, 37, or 61 strands for larger capacities. Typical ultimate tensile strength for standard AAAC alloys reaches 295-330 MPa, compared to 160-200 MPa for pure aluminum. Electrical conductivity at 20 degrees Celsius standardises at 52.5% IACS for the most common alloy grade, a slight compromise versus pure aluminum (61% IACS) offset by the ability to use longer spans and fewer support structures.

Utility companies and regional grid operators constitute the primary buyers, with project contractors and EPC firms serving as intermediaries for large infrastructure builds. AAAC suits medium to long span applications, coastal or polluted industrial atmospheres, and areas where conductor sag must be minimised. Buyers should confirm the specific alloy designation (6201-T81 or 1120 grade), stranding class, and whether testing certificates cover tensile elongation, DC resistance at 20 degrees Celsius, and wrapping tests per IEC or ASTM protocols. The supplier's listing mentions ISO certification but does not specify which standard or scope; buyers should request the certificate number and validity directly.

Zhengzhou Zms Cable Co., Ltd. is located at Changzhuang Village, Fumin Road, Zhengzhou 450042, Henan Province, China. The supplier holds an imported tier designation on the platform and a harbor trust tier, which represents a baseline verification level rather than an comprehensive audit. Notably, the response rate shows as 0.00 with zero average response hours recorded, indicating no engagement data is available through the platform. Buyers should treat this as an unknown communication pattern and initiate direct contact to gauge responsiveness.

The company profile available through the listing does not disclose manufacturing capacity, year of establishment, workforce size, revenue figures, or specific client references. No information about in-house testing laboratories, third-party inspection partnerships, or export licensing is provided. The listing mentions ISO certification without specifying the standard (ISO 9001, ISO 14001, etc.) or certifying body. Buyers are advised to request the certificate copy, scope statement, and validity period directly from the supplier before advancing to quotation or sample stages.
