What Is A Tape Wound Cores?

2023-07-14

At Transmart Industrial Limited, we specialize in the production of tape wound cores and other types of transformer cores. As experienced transformer core manufacturers, we know our products really well. In this article, we will delve into the world of tape wound cores, providing a comprehensive description of what they are, their uses, and their advantages.

Tape wound cores are a type of magnetic core used in various electrical and electronic applications. They are constructed by winding thin, continuous strips or ribbons of magnetic material, typically made of high-quality silicon steel or other magnetic alloys, into a tightly wound coil.

The winding process involves layering the strips or ribbons in a continuous manner, often with adhesive layers in between, to form a compact and uniform core structure. The individual layers are wound in a way that minimizes air gaps and maximizes the magnetic flux carrying capacity of the core.

There are different types of tape wound cores, including nanocrystalline cores, amorphous cores, mumetal cores,  silicon steel cores and many more.



Uses of Tape Wound Cores

The properties of tape wound cores make them indispensable in a wide range of electrical and electronic devices. Let’s look at some of the uses of tape wound cores.

1. Transformers

Tape wound cores are widely used in power transformers, distribution transformers, and specialty transformers. Some of the properties that make these cores ideal for use in transformers include their compact design and efficient magnetism. These properties contribute to high-performance power transfer, voltage regulation, and impedance matching in electrical distribution systems.


2. Aerospace Applications

These cores are also used in the aerospace industry for a wide range of purposes, including power distribution, signal transmission, managing electromagnetic compatibility, and more. The cores contribute to the safety, reliability, and functionality of aerospace systems thanks to their unique properties.


3. Inductors and Chokes

Another common application of tape wound cores is in the production of inductors and chokes. Tape wound cores are utilized in inductors and chokes to store and release energy in electrical circuits. They help filter out unwanted frequencies and reduce electromagnetic interference. In addition, they help maintain stable current flow in applications such as power supplies, filters, and motor drives.


4. Reactors

Tape wound cores are used in reactors used in various applications, including power electronics, renewable energy systems, and industrial machinery. They help control current flow, limit short-circuit currents, and maintain the stability of electrical systems.


5. E-Vehicles

Tape wound cores play a significant role in the development and operation of electric vehicles by enabling efficient power management and reliable electrical systems. E-vehicle manufacturers utilize tape wound cores for a wide range of purposes, including electric motor control, energy storage, managing electromagnetic compatibility, power conversion and more.
