1.Industry overview

As an important pillar of modern industry, the electrical industry undertakes the key tasks of power production, transmission, distribution, use and power conversion. With the transformation of the global energy structure and the concept of sustainable development, the electrical industry is ushering in unprecedented development opportunities. Especially in the context of global energy structure transformation and sustainable development, the electrical industry has become an important force to promote green and low-carbon development. In order to promote the development of the electrical industry, the quality and quantity of equipment necessary for the electrical industry should be improved. At the same time, the insulation material required in electrical equipment has also increased significantly.

2.Introduction of electrical equipment in the electrical field (takedry-typetransformer as an example)

The working principle and structure of the transformer determine that it must use insulation materials. The transformer performs the functions of voltage conversion, impedance conversion, isolation and voltage regulation through the principle of electromagnetic induction. Its internal structure includes iron core, winding and insulation materials. Core materials such as silicon steel sheets are used to improve magnetic conductivity, while the windings are isolated by insulating materials to prevent current leakage and short circuits ‌.

Insulating materials play a vital role in transformers, ensuring their safe operation and long-term stability.

3.Insulating material solutions for use in dry-type transformers in the electrical field

There are many kinds of insulating materials. Which kind of insulation material is low cost and can protect the transformer well, which needs us to carefully screen. After a lot of research and investigation, we put forward the solution of using 3240 epoxy  fiber glass laminate in dry-type transformer.

The benefits of this solution are as follows:

1.Resistance to mechanical stress: 3240 epoxy fiber glass  laminate has excellent mechanical strength for applications requiring durability and resistance to mechanical stress.

2.Prevent current flow, prevent short circuit: This laminate has high electrical insulation performanceand can prevent current flow, prevent short circuit.

3.Use in high temperature environment: 3240 epoxy fiber glass  laminate is resistant to high temperature and can not deform or lose performance in high temperature environment.

4.Use in harsh chemical environments: The laminate is resistant to various chemicals to ensure stability and performance in harsh chemical environments.

5.Customization: This material is easy to cut, drill and form, and can be customized and adapted to the specific requirements of various applications.
