Called safe voltage in the power system voltage below 36v, the following voltage 1kv called low-voltage, more voltage 1kv called high-pressure, direct supply line to the user known as distribution lines, such as user voltage 380/220v, known as low-voltage distribution lines, said strong electricity in the home decoration (which is home to the highest voltage). Strong electricity generally refers to the AC voltage above 24V. Such as household lamps, sockets, etc., the voltage in the 110V to 220V. Household electrical lighting, electric water heater, heater, refrigerator, TV, air conditioning, audio equipment and other electrical appliances are strong power electrical equipment.
Intelligent systems for construction equipment monitoring systems, security systems, communication networks, information networks and systems, automatic fire alarm and fire fighting linkage and other systems, centralized monitoring, control and management constituted for the purpose of an integrated system; families within a variety of data acquisition , control, management and communications control, or network lines, known as intelligent line (that is, home decoration as weak). Weak generally refers to the DC circuit or audio, and video lines, network lines, telephone lines, the DC voltage less than 24V. Phones, computers, televisions, household electrical signal input (cable line), audio equipment (output line) and electrical appliances are weak electrical equipment.
