Aluminum strip for transformer means that aluminum strip is used as conductive material in the high and low voltage windings of dry-type transformers and oil-immersed transformers.
The common thickness of transformer aluminum strip is 0.2-3.5mm, and the width is 10-1600mm. Normally, Huawei transformer aluminum strips are usually attached with blue plastic film and wrapped with kraft paper.
Aluminum strip for transformers is made of high-quality pure aluminum. It has the characteristics of high conductivity, soft texture, smooth surface and no burrs. It is an ideal material for the production of dry-type transformers and a key raw material for manufacturing transformer windings. It has good electrical conductivity to the aluminum strip. There are high requirements on many technical indicators such as rate, burr curling, side bending, and surface quality.
Since transformer aluminum strips have high requirements on the conductivity of the material and do not require strength, 1000 series aluminum alloy has become the best choice. Common alloys include 1050, 1060, 1070, and 1350.
Aluminum strips for transformers have good elongation and tensile strength, and can fully meet conventional processing requirements (stamping, stretching) and high formability.
Industrial pure aluminum has high plasticity, corrosion resistance, electrical conductivity and thermal conductivity, but its strength is low and heat treatment cannot enhance its machinability. It can be gas welded, hydrogen atomic welded and contact welded, but not easy to braze. It can easily withstand various Pressure processing and stretching and bending.
The temperature resistance level of the aluminum wire paint layer is between 180℃ and 220℃. When the welding problem is solved, the failure rate of transformers produced with aluminum will be smaller. Secondly, my country is rich in aluminum resources and the cost of aluminum wires is low. Production with aluminum The transformer costs less and is more competitive in the market.

High-quality manage manner:
On the same time, we are able to help take pix and shoot motion pictures of aluminum strips for you in case you want. Each product will be absolutely and punctiliously examined earlier than packing and delivery.
3104 aluminum sheet has suitable elongation, good corrosion resistance and good processability. Therefore, we can smelt it into alloys of different hardness according to different application requirements.
Aluminum circle for road sign refers to the aluminum circle used in the production of road signs. Because aluminum circles have strong corrosion resistance and weather resistance, aluminum circles are very suitable for the production of road signs.
Pvdf Coated Aluminum Coil is one type of Color coated aluminum coil, Color coated aluminum coil can be divided into polyester (PE) coated aluminum coil, fluorocarbon (PVDF) coated aluminum coil and epoxy roller coated aluminum coil.
Huawei Aluminum is a large-scale 5052 aluminum foil raw material manufacturer, with 30 years of experience in aluminum foil production and sales.
The 6063 aluminum sheet is a 6000-series aluminum alloy with magnesium and silicon as the main alloying elements. The strength of the 6063 alloy is lower than that of the 6061 alloy, and it has good extrudability, corrosion resistance, and good surface treatment performance.
1/8 aluminum sheet is often used in the manufacture of tanks and ships because of its strong hardness and corrosion resistance, etc.
