防爆燈嘅一般電壓係幾多

Typical Voltage for Explosion-Proof Lights in Factories

Explosion-proof lights in factories are commonly rated for 220V or 380V. 麻麻, 220V係標準, 其中380V唔太常見，通常用于功率要求極高嘅燈具.

Voltage for Mining Applications

用于採礦應用, the standard voltage for explosion-proof lights is usually 127V, with other voltages being exceedingly rare.
