煤礦風機必須有煤安全證書

喺易爆嘅環境中, 使用防爆電氣設備勢在必行, 並且必須附有有效的防爆認證. 在地下部署之前，需要為煤礦指定嘅電氣設備獲得煤礦安全認證, a mandate in line with China’s labor safety regulations.

Beyond the coal sector, industries such as petrochemicals, 冶金, and military manufacturing also rely on explosion-proof electrical equipment to maintain a safe production environment and avert potential explosive incidents.
