Import Aluminium Parallel Groove Clamp — Buy in Bulk from Supplier in China

The Aluminium parallel groove clamp supplied by Zhejiang Tianhong Electric Power Fitting Co., Ltd is designed for tap-off connections of aluminium alloy conductors, built to DIN48201 standards and compatible with ACSR conductors per DIN48204. It features a high-strength aluminium alloy construction that resists corrosion, with a parallel groove geometry that locks conductors securely to prevent electrical failures in high-load environments. The clamp is rated for overhead power line applications where mechanical stability and conductivity are critical.

Manufactured from aluminium alloy with typical conductivity ratings above 60% IACS, the clamp supports a standard range of conductor sizes from 16 to 300 mm², accommodating both solid and stranded variants. The groove spacing adheres to typical industry tolerances of ±0.5 mm to ensure consistent pressure distribution, while the bolt and nut assembly uses standard M10 or M12 fasteners for field installation. Surface treatment involves a typical hot-dip galvanization or anodizing process to enhance durability in outdoor conditions.

This clamp is primarily used in power distribution networks, substations, and renewable energy projects where reliable conductor joints are essential. Buyers typically source it in bulk for large-scale transmission and distribution builds, with packaging offered in standard 20 kg cartons or palletized loads. Lead time and MOQ should be confirmed directly with the supplier, as these vary by order size and current production schedules. The design simplifies on-site assembly, reducing labour costs in time-sensitive projects.

Zhejiang Tianhong Electric Power Fitting Co., Ltd is based in Wenzhou, Zhejiang Province, at No.82, Yuedu North Road, Changhong, Liushi. The company specializes in the production of electrical power fittings, with a focus on components for overhead transmission and distribution systems. Its product range includes clamps, connectors, and suspension hardware designed to meet international standards such as DIN and IEC.

The supplier operates within the imported tier and holds a harbor trust tier status, indicating a verified presence in the market. While the listed response rate is currently 0.00, the company’s profile confirms its role as a dedicated manufacturer of electrical fittings. Buyers should verify current production capacity and quality control processes directly with the supplier, as these details are not provided in the available data.
