與普通接線盒相比，防爆接線盒有哪些優點？

Explosion-proof junction boxes are specialized devices designed to operate safely in environments prone to flammability and explosions. Understanding their working principle begins with grasping what constitutes an explosive environment, typically characterized by combustible air, dust, or liquid media. The fundamental strategy in these boxes is isolating the internal electrical components from the external atmosphere, which may contain explosive dust or gases. This isolation prevents any internal electrical sparks from igniting external combustible materials.

優勢：

1. High Strength: These junction boxes are built to withstand harsh environments, ensuring durability and reliability.

2. Precision Engineering: They require a high level of finish on mating surfaces, with strict dimensional specifications to maintain the integrity of the seal.

3. Rigorous Sealing: All internal and external leads are meticulously sealed. This precise sealing guarantees that any sparks within the junction box will not ignite external combustible materials, thus preventing 燃燒 and explosions.
