What are transformer copper foils strips?
The transformer copper foils strips are the most important part of the transformer manufacturing.
It is mainly used to connect with the transformer core and output terminals.
The foil strip made of high-quality oxygen-free copper, which has good conductivity, has small contact resistance and low temperature rise, and can effectively reduce power loss and ensure long-term stable operation of the transformer.
By using high-quality insulated materials such as polyester film, polyesterimide film and polypropylene film, the transformer copper foils strips can be made into a double-sided coated product by vacuum coating technology.
It has good electrical insulation performance and high mechanical strength. It can meet the requirements of winding in transformers under different voltage grades.
Transformer copper foil is the first and important process of transformer manufacturing. It is not only the basic raw material for producing transformer windings, but also an important part to determine its quality.
The size, shape and thickness of the copper foil are directly related to the process properties of the transformer.
The transformer copper foil refers to a kind of special rectangular copper strip with specific width, thickness and length.
The surface of such strip is relatively smooth and flat, and its cross section is usually rectangular or trapezoidal.
The production method of this strip mainly includes cold rolling method, hot rolling method and casting method.
In addition to being used in power transformers, copper foil strips are also used in current transformers, instrument transformers and other products that require precise winding requirements.
What are the applications that copper foils strips for transformers can be used?
Transformer copper foil strip has high quality, stable performance and good price.
Therefore, it is widely used in the production of transformer winding.
Transformer winding refers to the process that windings made by transformer copper foil strips are wound on the core body or coil frame.
There are also some other common applications of transformer copper foil strip below.
- PCB industry: It is applied to the manufacturing of printed circuit boards (PCBs) which are used in various electronic products.
- Radial lead inductors: The radial lead inductors use copper foil strips to wind the coils. They apply to electrical equipment such as telecommunications devices (telephones, fax machines).
- Copper foil tape: Copper foil tape uses copper foil strips as raw materials, and it has a wide range of applications in the field of electromagnetic shielding and grounding.
- Copper belt: The copper belt is a thin belt made by rolling a thin layer of pure copper on the surface of auxiliary material with a certain thickness. It is widely used for making flexible printed circuit board (FPC) and other electronic products.
What are the advantages of using copper foils strips for transformers?
Transformer copper foils strips are used to make transformers and other related products that use copper conductors. The purpose of the transformer is to change the voltage or phase of an alternating current, while the phase-shifting transformer is used to introduce a constant phase shift between the input and output circuits.
Here are some of the benefits of using these foils:
- High conductivity – With a good electrical conductivity, you can be assured that your transformer will work properly.
- Low thermal resistance – This reduces the chances of a fire because it helps ensure that all parts remain cool during operation.
- Durable – They are made from materials that can withstand high temperatures and stresses, which makes them more durable than other types of foils.
- Cost effective – These types of foils are more affordable than some other options on the market today, which makes them a great option for anyone looking to save money on their project.
How to buy copper foils strips for transformers?
If you want to buy copper foils strips for transformers, you should know, there are many suppliers and manufacturers produce copper foils and supply to many industries like transformer industry.
But in fact, not all the suppliers have the ability to produce good quality products, some of them just choose cheaper materials but with high price which is not a good choice for users.
Here is a quick guide on how to choose a good supplier.
- First, you should ask the manufacturer whether they can do the inspection themselves before delivery. Most of the large manufacturers have their own inspection team, they will strictly inspect all the goods before delivery.
- Second, you should ask if they use 100% pure raw material to produce your goods, because there are some suppliers use recycled raw material or mixed raw material which may cause problem during using.
- Third, it is better to visit their factory by yourself and check the production line and warehouse by yourself. It will be great if you can check their production process and production equipment. Because it is very important for you to know how they control the quality from process till delivery.

Copper Coils
It may seem that a copper coil is a simple piece of coiled wire that can be wound and put to use. As with any form of industrial product, copper coils have to be precisely engineered to fit an application. The winding process has to be completed with precision to ensure the proper distance between the wires and the diameter of the opening.
Each product that uses copper coils requires that a certain number of turns be made to provide the correct amount of resistance. Inaccurate calculations can lead to inefficiency and possible failure of the coil or device. For this reason, the engineers at Metal Associates guarantee that they have closely examined the specification of an application such that the diameter, spacing, wire thickness, and number of turns exactly matches the design of the product where the copper coil will be used.
