Aluminum strip for transformer

Aluminum strip for transformer

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 transformer

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.

Aluminum strip for transformer common alloys

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.

Advantages of using aluminum strip for transformers

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.

Transformer structure

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.

Second: Aluminum coil winding

So as tu make sure the first-class of aluminum coil,the side remedy is made at the gadget

Third: Aluminum coil constant

The detection width and thickness deviation of the aluminum coil are consistent with the technical requipments of the customer,add a paper sleeve to the scrolls and connect aluminum coil with glass fiber tape

Huawei quality control system

We pay greater attention to great aid, supply scope, inspection, testing fashionable, cargo packing, after-sales service.
We have surpassed ISO9001 pleasant control gadget certification.

Aluminum strip for transformer

High-quality manage manner:

• 1) Checking the raw fabric of aluminum after they reach our manufacturing unit- Incoming quality manipulate.
• 2) Checking the information before the production line operated.
• 3) Have complete inspection and routing inspection in the course of slitting manufacturing-In system great control.
• 4) Checking the aluminum strip after they’re produced- very last great manipulate.
• 5) Checking the aluminum strip before shipment.

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.
