额定电压的确定：电灯额定电压的选择，主要应从人身安全的角度出发来考虑。在触电机会较多危险性较大的场所，局部照明和手提照明（如机床照明）应采用额定电压为36伏以下的安全灯，并应配用行灯变压器降压。春晨YCB扁电缆卷筒电缆对于安装高度能符合规程规定（一般情况下灯头距地面不低于2米，特殊情况下不低于1.5米），触电机会较少，触电危险性较小的场所，YCB扁电缆一般采用额定电压为220伏的普通照明灯，这样不需降压变压器，投资小，安装方便。春晨YCB扁电缆卷筒电缆

Determination of rated voltage: the selection of rated voltage of electric lamp should be considered from the perspective of personal safety. In places with more chances of electric shock and greater danger, local lighting and portable lighting (such as machine tool lighting) shall adopt safety lamps with rated voltage below 36 V, and shall be equipped with portable lamp transformer to reduce voltage. For places where the installation height can meet the regulations (generally, the distance between the lamp cap and the ground is not less than 2 meters, and in special cases, it is not less than 1.5 meters), the chance of electric shock is less, and the risk of electric shock is less, the general lighting with rated voltage of 220 V is generally used, so that the step-down transformer is not needed, the investment is small, and the installation is convenient.
