High-Conductivity Aluminum Strip for Transformer Winding

As a leading manufacturer specializing in aluminum processing and exporting aluminum strips, Haomei Aluminum focuses on the core needs of the global transformer industry. We are dedicated to creating high-conductivity aluminum strips specifically for transformer windings. With high-purity materials, precise specifications, and superior performance, we provide global transformer manufacturers with cost-effective and reliable conductor solutions, facilitating efficient upgrades in the power transmission sector.

Our high-conductivity aluminum strips for transformer windings are made from 1060-O high-purity aluminum with an aluminum content of no less than 99.6%, making them the preferred material for transformer windings. With comprehensive specifications, thicknesses range from 0.08mm to 3.0mm, widths from 10mm to 1500mm, and lengths can be flexibly customized to customer orders. Tolerances are strictly controlled within ±0.01mm, and edges can be chamfered for a burr-free and curl-free finish. It perfectly adapts to the winding requirements of transformers of different power ratings and types, providing precise matching for both small distribution transformers and large power transformers.

Core characteristics of our transformer aluminum strip closely match winding requirements, balancing performance and practicality.

The product’s most prominent advantage is its high conductivity, exceeding 61.5% IACS, far surpassing industry standards. This enables efficient current conduction and significantly reduces energy loss in transformer windings.

It also possesses excellent thermal conductivity, with a thermal conductivity coefficient of 227W/(m·K), quickly dissipating heat generated during winding operation and extending transformer lifespan.

The soft, O-state properties endow the product with excellent plasticity and ductility, making it easy to bend and wind, and resistant to breakage and deformation. This allows it to be adapted to complex winding processes.

Furthermore, it possesses good corrosion resistance, maintaining stable performance even under harsh conditions such as humidity and high temperatures, requiring no additional coating protection.

As an export-oriented enterprise, we have established a closed-loop quality control system covering the entire process from raw material procurement to finished product delivery. Every batch of products is traceable to its source.

Raw materials are selected from high-purity aluminum ingots of 99.6% or higher, undergoing rigorous composition testing to eliminate impurities. Production employs high-precision cold rolling and annealing processes, with full automation control.

The annealing process strictly follows a standard curve of 200℃×2h heating + 350℃×4h holding, ensuring a smooth, scratch-free, and oxide-free product surface.

Finished products undergo multiple tests, including conductivity, mechanical properties, and dimensional accuracy, conforming to international and domestic standards such as IEC 60287 and GB/T 3880. Certified by the ISO9001 quality system, their quality is stable and reliable. For many years, they have been exported to numerous countries and regions in Europe, America, and Southeast Asia, gaining widespread recognition from global customers.

Primarily used in the primary and secondary windings of transformers, high conductivity aluminum strip for transformer winding plays a crucial role in current conduction and energy conversion, particularly suitable for the high and low voltage windings of dry-type, resin-cast, and oil-immersed transformers. Compared to traditional copper strips, our high-conductivity aluminum strip maintains similar conductivity while weighing only 1/3 of copper strips, significantly reducing the overall weight of the transformer and facilitating transportation and installation. Costs are reduced by more than 30% compared to copper strips, effectively helping customers control production costs and enhance product market competitiveness. With its superior performance and high cost-performance, it is widely used in transformer manufacturing for various scenarios, including high-rise buildings, underground facilities, commercial centers, and humid coastal areas, providing a solid guarantee for the stability of power transmission.
