Conductive Copper Wire for Power Transmission

Product Overview

Our Coiled Copper Wire is manufactured with top-grade copper alloys including C1100, C1220, C11000, C12200, C10100 and C10200, complying with the latest GB/T3953—2024 Copper Wire standard. Featuring flexible temper options and a wide diameter range from 0.016mm to 14mm, our copper wire is supplied in coiled form for easy storage, transportation and on-site processing. With a minimum order quantity (MOQ) of 500 KGS, we cater to bulk ToB demands from new energy, power and transportation industries, while also accepting sample and OEM orders for small-batch customization. Backed by competitive pricing, fast global delivery and professional after-sales service, our High Purity Copper Wire has become a reliable choice for international industrial clients.

Key Benefits & Material Features

Superior Purity & Electrical Conductivity

All our copper wire grades feature a copper content of ≥99.90%, delivering exceptional electrical conductivity of ~100% IACS (International Annealed Copper Standard). This high purity ensures minimal resistance, making the C1100 Copper Wire and C1220 Copper Wire ideal for high-precision power transmission and energy conversion applications. The oxygen-controlled composition also enhances corrosion resistance in atmospheric and aqueous industrial environments, ensuring long-term durability.

Flexible Temper & Dimension Customization

We provide five temper options: O (soft), 1/4H, 1/2H, 3/4H and H (hard), matching different processing and application requirements. The ultra-wide diameter range (0.016~14mm) covers both micro copper wire for electronic components and heavy-duty copper wire for power equipment, meeting diverse industrial needs with one-stop supply.

Industrial-Grade Durability

Our Coiled Copper Wire is processed through precision drawing and annealing, ensuring uniform texture and excellent ductility for cold working and complex shaping. The coiled form maintains the wire’s structural integrity during transportation and storage, avoiding deformation and damage for on-site direct use.

Typical Applications

New Energy & Power Sector

The High Purity Copper Wire is a core material for new energy vehicles (motor windings, battery connections), solar photovoltaic power generation systems (solar panel wiring) and the national smart grid (power transmission lines), thanks to its high conductivity and stability.

Advanced Transportation & IT Industry

It is widely used in advanced rail transit (train power systems) and the new generation information technology industry (high-precision electronic component wiring), where reliable electrical performance and dimensional accuracy are critical.

Power Equipment Manufacturing

Our copper wire serves as a key material for various power equipment (transformers, generators, switchgear), complying with industrial standards for high-load and long-term operation.

Technical Specifications
