CUSTOMER CASE
Sockets are commonly used electrical devices that are connected to power cords and matched with plugs of the same type. Their interoperability is very strict, and they are usually divided into three types: open type, dark type, and mobile type. Its specifications are two-pole, three-pole, four-pole, 5A, 6A, 1OA, 15A, 25A, etc. There are many types of power sockets used at home and abroad.
Different countries or regions use different specifications, such as British standards, American standards, German standards, Japanese standards, and Chinese standards. There are differences in national standards. Most of the European production adopts British standards, and the jacks are national-shaped. Most of the American regions use American standards. Most of the jacks are flat or curved. Flat ring sockets have better contact performance than round sockets, so our country The flat contact structure is adopted. According to the national flag standard GB1002-80 "Single-phase plug socket type, basic parameters and dimensions" and GB1003-80 "Three-phase ring head socket type, basic parameters and dimensions" regulations, from July 1981 From 1st, it is not allowed to reproduce, purchase and install non-national standard round-pin socket plugs and other derivative products (except dual-use sockets).
Therefore, the use of circular ring seats does not meet the national standards. The type and size of plugs and sockets in my country are basically the same as those of Guan Guo and Japan, but the specifications are different. The spacing of sockets and the thickness of the plugs of sockets above 1OA increase with the increase of the ampere level.
When wires need to be laid in the ceiling of a combustible material structure, effective protective measures should be taken. Generally, metal pipes should be used for wiring, and the metal pipe must be well grounded. It is not allowed to install capacitors, Electrical switches and other flammable and explosive electrical appliances.
