Import Aluminum Conductor Steel Reinforced Cable — Buy in Bulk from Supplier in China

Aluminum Conductor Steel Reinforced (ACSR) cable consists of a central steel core surrounded by concentric layers of aluminum wire, combining the tensile strength of galvanized steel with the conductivity of aluminum. Zhengzhou Zms Cable Co., Ltd. manufactures this cable for overhead power transmission where spans exceed 200 metres or load requirements demand mechanical robustness. The steel core typically contributes 10-30% of the total cross-sectional area, with the aluminum strands providing the current-carrying capacity. Standard conductor sizes range from 6 mm² to 1,000 mm² cross-sectional area, with common stranding configurations of 6/1, 26/7, 30/7, or 54/7 aluminum/steel wire ratios depending on mechanical loading requirements.

The aluminum alloy employed is typically 1350-H19 grade, offering 61.2% IACS conductivity with a minimum tensile strength of 160 MPa, while the steel core uses zinc-coated (galvanized) wire with tensile strength between 1,300-1,600 MPa. The zinc coating weight is typically 200-260 g/m² for standard atmospheric conditions, though heavier coatings apply for corrosive environments. Stranding follows IEC 61089, ASTM B232, or BS EN 50182 standards, with lay lengths optimised to balance conductor flexibility against strand migration under cyclic loading. Galvanic corrosion between dissimilar metals is mitigated by the zinc layer and grease compounds applied during manufacture.

ACSR cable serves utility companies for primary and secondary transmission lines from 11 kV to 800 kV, rural electrification projects, and industrial substation connections where overhead construction remains economical. Buyers include national grid operators, EPC contractors, and large-scale renewable energy developers requiring long-distance power evacuation from remote wind or solar sites. The cable's self-supporting nature eliminates the need for separate messenger wires, reducing tower loading and right-of-way costs. For orders from Zhengzhou Zms Cable Co., Ltd., buyers should confirm conductor code (e.g., Panther, Dog, Wolf per ASTM naming), reel lengths, and whether IEC or ASTM dimensional standards apply to their jurisdiction.

Zhengzhou Zms Cable Co., Ltd. operates from Changzhuang Village along Fumin Road in Zhengzhou, Henan Province, with postal code 450042. The supplier holds an imported tier designation on the platform with a harbor trust tier, indicating a baseline verification level. The response rate shows 0.00% with zero average response hours recorded, suggesting no recent buyer engagement through the platform messaging system. This absence of response data means buyers should initiate contact through multiple channels and verify direct communication pathways before relying on platform-mediated enquiries.

The company's product focus centres on power cable manufacturing for transmission and distribution applications, with ACSR forming part of their overhead conductor portfolio. No verified factory audit details, ISO certification numbers, or specific production capacity figures appear in the available profile. Buyers should request current ISO 9001, ISO 14001, or IECEx certificates depending on their market requirements, and confirm whether the company holds CCC certification for domestic Chinese projects or export-focused type test reports from recognised laboratories such as KEMA or CESI. The Henan location offers proximity to aluminum processing and steel wire drawing industries in central China, potentially supporting vertical integration in raw materials.
