Special topic on weak current engineering

Weak current engineering is a classification of electric power applications. Electric power applications can be divided into two categories: strong electricity and weak electricity according to the strength of the power transmission power. The electricity used in buildings and building complexes generally refers to weak current of AC 220V50Hz and below. It mainly provides electric energy to people and converts electric energy into other energy sources, such as air conditioning electricity, lighting electricity, power electricity, etc.
