  LED 防爆燈的結構形式

  2023-11-20 技術規格

  The design of explosion-proof lighting fixtures must be tailored to the specific zone and area of explosive gas environments. For instance, in Zone 1 areas, flameproof (explosion-proof) lighting fixtures are mandatory; in Zone 2, both flameproof and increased-safety fixtures can be used for fixed lighting, while portable lighting must be...

  提高安全性的電氣設備繞組

  2023-11-18 技術規格

  In enhanced-safety electrical equipment, such as explosion-proof motors, transformers, electromagnetic wires, and ballasts for fluorescent lamps, a portion includes internal windings. The requirements for these windings, both mechanically and electrically, are higher than those for standard windings. Generally, the insulated wire used for winding these coils should be double-insulated, and...

  提高安全性 電氣設備電線連接

  2023-11-18 技術規格

  For enhanced-safety electrical systems, wiring connections can be categorized into external electrical connections (where external cables enter the enhanced-safety enclosure) and internal electrical connections (between components inside the enclosure). Both types of connections typically utilize copper-core cables due to their high mechanical strength, low resistance, and superior conductivity. External Electrical...

  提高安全性 電氣設備外殼保護

  2023-11-18 技術規格

  Enhanced-safety electrical equipment must be encased in a properly designed enclosure. This casing is crucial not only for assembling electrical components but also for shielding them from external threats such as solid particles, moisture, and water. These elements pose a serious risk as they can lead to short circuits, insulation...
