How many volts is the voltage of a home socket in China?

There are two main voltage and frequency standards in the world. One is 110-120 volts, 60 Hz in North America, and comes with Type A and Type B plugs. The other is the European standard of 220-240 volts and 50 Hz, and the plugs used range from type C to type M.

Their differences are mainly due to historical reasons.

In the United States, Edison insisted on using 110V direct current instead of alternating current in the New York power supply system he built.

In China, the ground voltage is about 220V, that is, it is usually normal in the range of 215-235V, and even lower is no problem.

The voltage of a household socket in China is usually 220 volts.

Including in the range of 215-235V, it is within the normal range. Volts are the International System of Units.

The base unit of voltage is denoted in . It was mainly named in honor of the Italian physicist Alessandro Ford's Volt. Voltage level.

Rated voltage level series of power systems and power equipment.

Summary. Dear, I'm glad to answer for you: the live wire is 220 volts, and the ground wire is 0.

The conventional electricity voltage in our country is divided into 220V and household, and 380V is industrial. Therefore, the socket is generally divided into 220V and 380V, specifically two holes and three holes, generally 220V, we call single-phase electricity, used for household appliances, such as computers, TVs, fans, refrigerators and other common appliances, four-hole and five-hole are generally 380V for power, we call it three-phase electricity, used for industrial appliances, such as motors, industrial equipment and other individual high-power household air conditioners are also three-phase electricity. Generally, the socket cannot be marked with V, but with A.

Most household sockets are available in 10A and 16A. 10A is generally used to supply power for ordinary low-power household appliances, such as electric kettles, washing machines, microwave ovens, etc.; 16A is generally used to supply power to higher-power household appliances, such as air conditioners, electric water heaters, etc. Generally, electrical appliances are 220V.

First, in engineering applications, the material composed of insulating substances with resistivity greater than how many ohms is called insulating materials.

Pro, the resistivity is at 10The insulating material above m is absolutely insulating.

2.According to the physical characteristics, insulating materials are divided into ( ) insulating materials, () insulating materials and semi-solid and solid insulating materials.

Pro, natural insulating materials and synthetic insulating materials can be divided into: gas insulating materials, liquid insulating materials and solid insulating materials according to the physical state.

The voltage of a household socket in China is usually 220 volts. Including in the range of 215-235V, it is within the normal range. Volts are the basic unit of expression of voltage in the International System of Units.

It is mainly named in honor of the Italian physicist Alexandro Ford's house. Voltage Rating: Rated voltage level series of power systems and power equipment.

The home uses 220v

In the transmission of electricity, now the country's highest overhead line is 1000kV According to international practice, the general 1 thousand volts below is called low voltage, 3 35 thousand volts and below is called medium voltage, 63 220 thousand volts is called high voltage, 330 750 thousand volts is called ultra-high voltage. The maximum voltage level of China's built power grid is 750 kV AC and 500 kV DC.

UHV power grid refers to the transmission network with voltage levels of 1000 kV AC and 800 kV DC and above. The adoption of UHV transmission technology will effectively increase the transmission distance, increase the transmission capacity, reduce the transmission loss, reduce the transmission cost, and achieve a wider range of optimal allocation of resources.

The maximum voltage level of China's built power grid is 750 kV AC and 500 kV DC.

The Yunnan-Guangdong 800 kV UHVDC transmission demonstration project started in Chuxiong, Yunnan Province in 2006, which is the world's first 800 kV DC transmission project and the world's highest voltage DC transmission project.

China's civil standard voltage is 220V, and the frequency is 50Hz.

The standard of 220V mains power supply is as follows: between the live line and the neutral line: 220V 10%, between the neutral line and the ground wire: less than 5V and more than 0V, between the live line and the ground hall line: less than 220V 10%.

The common AC frequency in the world is 50Hz (Hertz) and 60Hz (Hertz), and the civil AC voltage distribution ranges from 100V to 380V, and Japan and the United States are 110V.
