There are so many models and specifications of power sockets and manufacturers how should we choose to buy it correctly, as manufacturers from the quality, waterproof performance, price, after-sales and manufacturers and other aspects. Industrial plug is suitable for industry, generally divided into 3 core, 4 core, 5 core, etc., current is generally divided into 16A, 32A, 63A, 125A, 250A, 420A, etc., protection grade can be divided into IP44, IP67 these two, for these are more conventional. In general, it is used with industrial sockets and industrial connectors. A switch is arranged between the weatherproof socket resistance and the electromagnetic switch, the fuse and the electromagnetic switch is connected with the power line, the power line is arranged on the electromagnetic switch normally open switch, the electromagnetic switch normally open switch is connected with the jack. The embedded socket is embedded in the integrated communication cabinet and provides dc basic electric power to the communication and data equipment in the same cabinet. It also has certain universality.

First, quality selection

Everyone wants to buy high quality products when buying power sockets, but now there are a lot of manufacturers on the market to produce and sell power sockets, and the quality gap between manufacturers is bigger, so as an ordinary consumer, how do we distinguish the quality of power sockets?

1, look at the appearance

High quality power socket design looks very texture, which can mainly be attributed to its high quality shell has a strong anti-aging and waterproof work ability, if there is not a system power socket looks weak feel do not buy;

2. Look at the certification mark

As a high quality power socket should have relevant quality certification (such as CCC quality certification), I tell you, even if we do not distinguish the quality, just look at the certification mark;

3. Take a test

The best way to test the quality of a system power socket is mainly the actual situation of the enterprise, when we need to buy, we can now take samples from a number of manufacturers can be analyzed and tested, and finally choose the quality of the power socket manufacturers can be better.

Two, waterproof performance selection

Since we have bought the power socket, it shows that we have certain requirements for waterproof ability, the waterproof ability of the power socket is generally marked with IPXX, the first X value is 0 to 6, the second X value is 0 to 8, so the highest waterproof level of the power socket is IP68.

It is recommended that you choose the power socket according to your own actual situation to choose waterproof level, specific choice of which waterproof level of plug socket hard steel according to the use of the environment, we do not put the waterproof level of plug products in the environment beyond its protection ability to use (to avoid safety problems).

Three, the choice of price

Everyone wants to save money on electrical outlets. Here's a reminder that there are places to save money and places to spend money! For example, a normal market price of power socket is 50 yuan, most manufacturers are selling 50 yuan or more than 50 yuan, and there is an enterprise as long as 35 yuan can, so you save money to buy 35 yuan of power socket price feel they made, I want to ask you: power socket manufacturers sell things will lose money? So, under normal circumstances, the price of a power socket fluctuates above cost. If the price of a product is too low, we must not buy it in order to save money, although a high price does not necessarily buy high-quality plugs and sockets, but a low price is less likely to buy high-quality power sockets.
