Import Aluminium Parallel Groove Clamp Pg571 B — Buy in Bulk from Supplier in China

The Aluminium Parallel Groove Clamp PG571 B from CROP Technology Group is a mechanical connector designed for overhead line applications, specifically for joining bare or insulated aluminium conductors. The PG571 series includes variants such as PG571-0A, PG571-1A, PG571-1B, PG571-2A, and PG571-2B, each tailored to conductor ranges between 16 to 240 sqmm. The clamp uses 2 or 3 bolts depending on the model, with dimensions like 42 to 70 mm in length, 36 to 62.5 mm in width, and radii from 5.5 to 10.5 mm. For insulated aerial bundled conductors, the insulation must be stripped before installation, and a UV-resistant plastic PG cover is required to restore insulation integrity.

Constructed from electrical-grade aluminium, the clamp ensures high conductivity and corrosion resistance, with DACROMET-finished screws as standard and hot-dip galvanised options available. The design accommodates aluminium-to-aluminium, copper-to-copper, and copper-to-aluminium connections, with tinned variants for enhanced performance in mixed-metal applications. Typical industry standards for such clamps include compliance with IEC 61284 for mechanical and electrical performance, as well as material purity levels of at least 98.5% aluminium for optimal conductivity.

This clamp is widely used in utility and transmission line installations where reliable mechanical and electrical joints are critical. Buyers typically include electrical contractors, utility companies, and infrastructure developers sourcing wholesale quantities for large-scale projects. The product is shipped in standard packaging with no special storage requirements, as it is fire-resistant and non-hazardous. Lead times and bulk trade terms are available upon request, with the supplier based in Yueqing, Zhejiang, a major hub for electrical components manufacturing in China.

CROP Technology Group is based in Yueqing, Zhejiang Province, China, with its registered address at No.77, Zhongji Road in the Yuecheng Industrial Zone. The company operates as an imported-tier supplier, specialising in electrical components for overhead transmission and distribution systems. Its product range includes clamps, connectors, and fittings designed for utility-grade applications, with a focus on aluminium-based solutions for conductor joining and termination.

The supplier’s profile indicates a harbor trust tier, but no verified response rate or average response time is currently available. This suggests limited engagement activity on the platform, though the company’s physical presence in a major manufacturing hub for electrical hardware provides a baseline of credibility. The listing does not provide details on certifications, production capacity, or client history, so buyers are advised to request these directly for validation.
