Two, industrial plug and socket purchase skills
1. According to the use of power equipment using single-phase or three-phase power to determine the number of poles of the plug and socket. Single-phase power selection 3-pole, three-phase power if the winning line is grounded can choose 4-pole, otherwise you must choose 5-pole. Then, according to the rated voltage of the equipment, operating current level and frequency selection of the appropriate specifications.
2. Rated voltage less than or equal to 50V electrical accessories of the key or keyway position clock, see Exhibit 1-5; rated voltage greater than 50V electrical accessories of the ground position clock, see Exhibit 1-6. can be based on the rated operating voltage and frequency reference selection.
3. You can see the plug sleeve from the jack. In general, the material will be nickel-plated treatment, the surface is smooth, no patina phenomenon, the thickness is generally between 0.5-0.8mm, pulling the copper piece, feel the elasticity; if possible to open the back cover, and then carefully observe the internal structure of the socket, the internal connecting line should be thick, the soldering should be uniform, there can be no false soldering.
Now the use of electrical appliances is very high, some factories will use large industrial appliances, then industrial plug and socket brands and purchase skills what, I think through the introduction of the above small introduction you ah for these also understand it, then if you want to ah yo know more about the decoration of information, please continue to pay attention to it.
