[0002] As a key equipment box that carries electrical components, the electrical cabinet plays a pivotal role in the rapid development of today's society. It is not only widely used in many industries such as chemical industry, environmental protection, electricity, metallurgy, industry, nuclear power, fire safety monitoring and transportation, but also the key to ensure the normal operation of these industries. With its solid steel structure, the electrical cabinet provides solid protection for the internal components, ensuring that they can work stably in various environments.
