Brief introduction:


◆　Explosion-proof power distribution control cabinet has the explosion-proof technologies, such as positive pressure,explosion suppression, and encapsulation. Inside the cabinet, it can install various kinds of non-explosion-proof instrumentations, control instruments, display instruments, and low-voltage apparatus. It is widely used in explosive atmospheres (II Class B Area 2) in petroleum and chemical industry.
◆　Explosion-proof power distribution control cabinet will bring clean inactive gas into the plemum by the intelligent control system and pressure control system inside the cabinet. It will form micro-positive pressure to prevent the hazardous gases outside the cabinet from entering the cabinet to reach the explosion-proof purpose.
◆　Explosion-proof power distribution control cabinet has been approved by the explosion-proof inspection agency and obtained the CQC certificate. The certificate number is CQC2008010301312226, CQC2012010301570364.
