Nowadays, some friends who often travel to European countries are relatively familiar with industrial plugs. Industrial plugs are suitable for industry, generally divided into 3-core, 4-core, 5-core, etc. The current is generally divided into 16A, 32A, 63A, 125A, 250A, 420A, etc., and the protection level can be divided into IP44 and IP67, which are relatively conventional. Generally, it is used with industrial sockets and industrial connectors. A socket into which one or more circuit wiring can be inserted, through which various wiring can be inserted to facilitate connection with other circuits. Embedded socket is embedded in the integrated communication cabinet, which is a power supply device that provides basic DC power for communication and data equipment in the same cabinet. It also has certain versatility. However, many people will have some problems when purchasing this product, so they can't buy the right product. This article will give you some tips about purchasing industrial plugs, so that you can have a better understanding of this product.I. Regular shopping mallsWhen purchasing industrial plugs, we will try to choose some ordinary shopping malls, such as some large shopping malls or some reputable specialty stores. The quality of products in these places is relatively high. In some roadside shops, the quality of such products that may be sold has not passed the inspection, and there are likely to be some unqualified products.2. Famous brandsFor all products, the brand effect is very important, because after a long period of market testing and customer certification, a product will be popular among brands and become a well-known brand, so the same is true of industrial plug products, because in China, the popularity of this product is not far away, only some well-known brands may have a long history in developing this product, and the technology is quite mature, so the quality and performance of the product are definitely better than the products that want to join the industry profitably now.III. Certification marksHigher quality industrial plugs must have passed the quality appraisal of some certification centers and possessed some certification marks. Therefore, when purchasing products, we must check some certificates and certification marks of products, and the relative performance with certification marks must be guaranteed.IV. Product qualityIn addition to some product certification, we can actually do some simple operations on the product to judge the relative quality of the product, and carry out experiments on some plug-ins. We can confirm that the insertion and contact of the product are good and won't loosen, etc. It is convenient to pull out the product without using too much force. Some contact situations are that the product quality is relatively poor, which we must avoid in the process of purchasing.V. Application of productsIndustrial plugs are consistent with all plug and socket products in terms of power, but they also need to match the correct power usage. Just like we buy any product, we should choose the right one. Before buying industrial plugs, we should also consider the power of the electrical appliances that the product is used to connect with and some practical requirements. For some high-power electrical appliances, 16a plugs are needed, while for some low-power electrical appliances, 10a plugs are enough. In this respect, we must carefully analyze the demand, otherwise, in the subsequent use process, due to load current, voltage, etc., there will be power failure, explosion and other dangerous situations.
