  1. The main frame is made of Q235 profile steel with electrostatic powder coating. The cabinet body has flameproof surfaces on all sides, fixed hinges on the sides, and the cover is fastened to the cabinet body with screws at intervals of 100mm. Accessories are made of 316 stainless steel.。

  2. The functional compartments of the explosion-proof distribution cabinet are isolated from each other, divided into an electrical installation compartment and a wiring compartment, with each compartment serving independent functions.。

Flameproof Type IIC explosion-proof distribution cabinets are suitable for all flammable gases within Class IIB and below.。

  1. The main frame is made of Q235 profile steel with electrostatic powder coating. The cover adopts circular spigot flanges or threaded flanges, with the flange fastened to the cabinet body with screws at intervals of 80mm.。

  2. The Type IIC explosion-proof distribution cabinet features an attractive appearance, high explosion-proof performance, high protection rating, and easy maintenance, making it an ideal power distribution device for explosion-proof low-voltage power supply systems in the petroleum, chemical, and other industries.。

Dust explosion-proof distribution cabinets are suitable for dust environments containing conductive dust. The explosion-proof rating under the new standard is tD, and under the old standard is IIIC.。

Positive-pressure explosion-proof distribution cabinets: PZ grade is suitable for Zone 2 explosion-proof locations, and PX grade is suitable for Zones 1 and 2 explosion-proof locations.。

The main frame adopts a GGD cabinet structure, formed by bending and welding Q235 steel plate, followed by overall shot blasting and internal and external high-voltage electrostatic powder coating. It can also be formed by bending and welding high-quality stainless steel plates such as SUS304, SUS316, or 316L, with overall brushing to a stainless steel natural finish. Alternatively, the external surface can be powder coated according to customer requirements. The external dimensions are not restricted and can be made to any size as required by the customer.。
