Encapsulation essentially creates a protective “shell” around the components by fully enclosing them in a compound or another non-metallic enclosure with adhesion. Encapsulation prevents ignition of the explosive gases or vapors due to potential sparking, arcing or excessive heat. Although reliable, bolted enclosures are very heavy and take time to open and close due to the large number of bolts. The explosion-proof distribution box is the "invisible guard" that ensures the safe operation of the power system in these special environments. What is an explosion-proof distribution box? An explosion-proof distribution box is a special electrical equipment designed for flammable and explosive. They're designed to meet two critical challenges: contain internal explosions and prevent external ignition sources from interacting with volatile atmospheres.
