Import Bare Acsr Overhead Conductor Acsr 490/65 — Buy in Bulk from Supplier in China

Bare ACSR Overhead Conductor 490/65 consists of aluminum wires stranded around a high-strength steel core, offering a balance of electrical conductivity and mechanical strength for overhead transmission lines. The 490/65 designation refers to the cross-sectional area of aluminum (490 mm²) and steel (65 mm²), providing a typical current rating of 800 - 1000 A at 75°C ambient temperature, depending on span and sag conditions. The conductor is designed for medium to long-span applications where lightweight and high tensile strength are critical, such as rural electrification or sub-transmission networks.

The aluminum used is standard 1350-H19 grade for electrical applications, while the steel core is typically galvanized to class A or C for corrosion resistance in temperate climates. Stranding follows a concentric lay configuration, with aluminum layers in opposite directions to neutralize torque and reduce fatigue under wind load. The conductor’s lightweight design reduces tower loading by up to 20% compared to copper alternatives, a key advantage in mountainous or flood-prone regions where structural integrity is paramount.

Utilities and EPC contractors source this conductor for 66 kV to 220 kV lines, where its typical sag characteristics at 1000 m spans allow for efficient tower spacing. The conductor is supplied in wooden or steel drums, each coil weighing 1800 - 2200 kg, depending on drum size. Buyers confirm external diameter, breaking load, and elongation at 1% proof stress before bulk orders, as these parameters directly impact line design and regulatory compliance.

Zhengzhou Zms Cable Co., Ltd. operates from Changzhuang Village, Fumin Road in Henan Province, China, specializing in overhead conductors for power transmission and distribution. The supplier is classified under the imported tier, indicating a focus on export markets, with a harbor trust tier suggesting baseline verification for international trade. No response rate or average response time data is available at this time, so buyers are advised to confirm lead times directly.

The company’s product range includes ACSR conductors tailored for utilities and infrastructure projects, with custom sizing options to match project-specific current and span requirements. While the listing does not specify certifications, the conductor is described as compliant with industry standards for conductivity and mechanical performance. Buyers should request third-party test reports for tensile strength, elongation, and corrosion resistance to validate claims.
