What is the strong current and weak current in the property?

Hello! Accurately speaking, the habit of electronic people is divided into two parts: strong electricity (electricity) and weak electricity (information). There are both connections and differences between them. Generally speaking, strong electricity is treated by energy (electricity), which is characterized by high voltage, high current, high power and low frequency. The main consideration is to reduce loss and improve efficiency. Weak current is mainly information processing, that is, information transmission and control, characterized by low voltage, low current, low power and high frequency. The main consideration is the effect of information transmission, such as information transmission. Strong electricity refers to the voltage of more than 24V, which is called strong electricity, including high-voltage transportation wires, household 220V two-stage wires, industrial production with 380V alternating current, etc ... Weak electricity refers to wires that transmit information such as telephone, video and network cable.
