Method for Quickly Checking the Authenticity of Explosion proof Distribution Box Certificate

The rise of national infrastructure has brought fires to the power transmission and distribution industry. Explosion proof distribution boxes, as a very important electrical equipment, have a high demand. This has led to an increasing number of distribution box manufacturers in China, intensifying competition and inevitably resulting in the emergence of some counterfeit and inferior products in the market. How to accurately determine whether the distribution box is a qualified product is a concern for every customer. Now the editor will give a rough example:

1. Search for the business license of the explosion-proof distribution box manufacturer:

Enter the company name on the website of the "National Enterprise Credit Information Publicity System" to check the business period and scope. Note: If the displayed content is sales and production of explosion-proof distribution boxes, then the company is a production type. If it is displayed as selling explosion-proof distribution boxes, then it is a trading company. In contrast, explosion-proof distribution boxes purchased by manufacturers have relatively high cost-effectiveness in terms of price and after-sales service.

2. Explosion proof distribution box product qualification:

Explosion proof certificate and national industrial product production license. Note: Both certificates must be complete and provided online, as the explosion-proof certificate is specific to the product, and the production license requires a series of hardware and software facilities, such as the number of technical personnel, production equipment, quality system, process inspection, etc. Many companies have explosion-proof certificates for their products, but they do not have a national production license for industrial products. There is a risk of the product being accepted as it does not meet the requirements for qualified explosion-proof products.
