Shenhai Explosion-Proof
An explosion-proof positive pressure cabinet, also known as a positive pressure explosion-proof distribution cabinet, is a type of distribution cabinet designed for hazardous environments. It features explosion-proof, corrosion-resistant, dustproof, waterproof, and heat-dissipating functionalities. The cabinet boasts an IP65 protection rating and an explosion-proof grade of Ex px IIC T6.
Basic Structure:
The explosion-proof positive pressure cabinet utilizes a GGD-type cabinet structure, divided into two main sections: the positive pressure chamber and the control chamber, with wiring rooms included. Depending on their relative positions, these cabinets are available in three different shapes: vertical (top and bottom), horizontal (left and right), and piano-type structures. The opening method varies with the structure; the vertical cabinets have front and rear doors, with the upper and middle sections serving as the positive pressure chambers and the lower section as the control chamber. The horizontal cabinets feature left-right and front-back opening doors, while the piano-type cabinets have side and rear openings.
Internal Structure:
Internally, the explosion-proof positive pressure cabinet uses a baseplate mounting approach, equipped with cable trays and operating mechanisms. Its layout can be customized based on the installed instruments and electrical components. The cabinet is made of carbon steel with a powder coating, 2.5mm thick, or 304 stainless steel with a brushed finish, also 2.5mm thick, coated with explosion-proof anti-fingerprint paint. The fasteners and door handles are made of 316 stainless steel, featuring a protective door with explosion-proof glass windows.
