Is the traffic light weak or strong?
The strong and weak electricity are not completely separate, weak system operation also needs to supply electricity to the power system, power system automation, but also to many weak technology and equipment applied to intelligent control.
Strong current and weak current do not refer solely to the magnitude of the voltage or current of the power supply, but to the whole system
When it comes to the use of power, AC power supplies used by any electrical device are of high voltage.
For example, lighting, air conditioning, power and so on belong to the category of strong electricity, and fire, security, building intelligent systems, these are weak category.
