How to choose high quality explosion-proof positive pressure cabinet?

There are no fewer than a dozen or even hundreds of explosion-proof electrical products that are currently on the market, and for such a large number of product manufacturers, there are not many manufacturers who can come up with complete design documents for explosion-proof positive pressure cabinets . Not much regular explosion-proof manufacturers. Explosion-proof electrical products are related to people's lives and property safety, and product design work is the basis of explosion-proof electrical products. Some manufacturers do not have to design, even the most basic explosion-proof knowledge and requirements are not clear, they begin to manufacture, not to mention Said to engage in product testing, preparation of product drawings and documents. Some manufacturers often buy a prototype, make products according to the painting and scoop, put it on the market, as product standards, drawings, explosion-proof certificate, test report, etc. simply do not. If it is really needed, it should be dealt with by means of copying, fraudulent use, and borrowing. This product is certainly not qualified, therefore, the majority of customers want to choose a formal explosion-proof positive pressure cabinet manufacturers.

As the manufacture of explosion-proof electrical products, there is a complete production system, which will never be reduced due to the entry into the market economy. It is only in the market economy that these tasks are faster and take less time. There are also some companies that use their own products nameplate or use other manufacturers' products to fight their own nameplate, the reason is that they do not have the technical ability to do the basic guarantee, can not reach the basic requirements for the production of explosion-proof electrical products, in a huge With interest, it is quite risky. Some companies neglected to understand the integrity of product design data, and other product files were incomplete, improper use of technical personnel or simply no technical management personnel, leaving the product with many problems. To give a simple example: The product specification and product are marked with explosion-proof rating IIBT6, while the product standards and test reports, product certificate of conformity is marked as IIBT4. Errors like this can be seen everywhere. Other products found problems in the tests. They were only temporarily processed. Zhengzhou Hualong Hualong Explosion-proof Electrical Co., Ltd. has 5 professional engineers and 12 senior technical engineers. Therefore, you do not need to worry about products.

As an electrical product, no matter what the application, the most important assessment index is how the electrical performance, especially explosion-proof electrical products, due to its structural particularity, so its higher electrical performance requirements. There are many companies that tend to focus only on explosion-proof structures and neglect electrical performance indicators. This is dangerous. In China, there have been many accidents caused by poor electrical performance, which led to arc short circuit, burned through the steel shell or caused damage to the shell. The end result of these accidents was caused by poor electrical performance. Therefore, our company has professional inspection personnel responsible for the electrical performance of explosion-proof electrical products.
