Which is better, the champion socket or the bull socket?

Precautions for purchasing sockets:

Look at the brand first: buy products produced by large and medium-sized enterprises first. For example, Klebo passed the national quality supervision and spot check for five times in a row and was listed as a national key new product.

Second, look at the signs: it depends on whether the product has the "CCEE" and "CCC" safety certification marks, and whether the product has the detailed address and telephone number of the manufacturer or supplier. The national standard clearly stipulates the rated current, which is divided into six grades, namely 6A, 10A and 16A. If there are other mark grades, it is a non-standard product.

Third, look at the plug: China's national standards stipulate that the plug form is flat, and the two poles are grounded, commonly known as three-pole plug. Cylindrical plugs are outdated products, and consumers should never buy them.

In addition, you should also pay attention to the following aspects when purchasing:

First, you should go to large shopping malls and supermarkets to buy well-known brands of power plugs and sockets;

Two, should check whether the logo on the plug and socket is complete, including the name of the enterprise, specifications, rated current value, power nature symbols and related warnings. ;

Three, should choose the corresponding plug socket according to the power of electrical appliances, two kinds of household appliances with higher power should not be inserted into the same socket;

4. After the plug is inserted into the socket, it should be in good contact without looseness, and it can be pulled out without too much effort;

5. Don't plug high-power household appliances into sockets with low rated current;

6. When the specifications and sizes of the plug and the wall socket do not correspond, do not artificially change the size or shape of the plug;

7. When the power cord or plug is damaged and needs to be replaced, please ask a professional to replace it;

Eight, found that the socket temperature is too high or arcing, ignition, poor contact between plug and socket, plug inserted too loose or too tight, should stop using and replace in time.
