Explosion-proof distribution cabinets/distribution boxes - the guardians of power safety in dangerous environments

In high-risk environments such as petroleum, chemical, coal mining and gas industries where flammable and explosive gases exist, ordinary electrical equipment may become a fatal hazard. Our explosion-proof distribution cabinets and boxes are specially designed for these extreme working conditions. Through exquisite flameproof technology, robust shell structure and strict international certification, they completely isolate electric sparks from hazardous media, providing the most solid guarantee for the safety of your critical equipment and personnel.

Core value: Safety is the sole principle of our design
We are well aware that in dangerous areas, safety is the lifeline. The core value of our products lies in:
Absolute safety isolation: Advanced composite explosion-proof technologies such as flameproof type (Ex d) and increased safety type (Ex e) are adopted. When an electric arc or spark explosion occurs inside the cabinet, its high-strength shell can effectively withstand the internal explosion pressure and prevent the flame from spreading to the external dangerous environment, fundamentally eliminating the occurrence of explosion accidents.
Impeccable and sturdy protection: The box body is welded from high-strength cast aluminum alloy, stainless steel or high-quality carbon steel, with a solid and durable structure. The surface has undergone fine powder coating or special anti-corrosion treatment, featuring an extremely high protection level (IP65/IP66/IP67), effectively resisting moisture, salt spray, corrosive chemicals and external mechanical shock.
Strict compliance certification: The product fully complies with the Chinese explosion-proof standard (GB3836), the EU ATEX Directive (2014/34/EU), and the international IECEx system requirements, and has obtained the corresponding explosion-proof qualification certificates, ensuring that the product can be safely and legally used in both domestic and international markets.
Precise customization capability Based on your specific hazardous area classification (Zone 1, Zone 2, Zone 21, Zone 22, etc.) and gas group (IIC, IIB, IIA), we tailor a complete solution for you, including the number of circuits, brands and specifications of electrical components (circuit breakers, contactors, frequency converters), and the methods of incoming and outgoing lines.

Explosion-proof marking and applicable environment

Our products cover a variety of explosion-proof types and are suitable for different hazardous environments

Explosion-proof type	Explosion-proof marking (example)	Introduction to the Principle	Typical application scenarios
Flameproof type	Ex d IIC T6 Gb	The shell can withstand internal explosions and prevent the spread of flames	Zone 1 and Zone 2 areas, such as the periphery of chemical reaction vessels
Increased safety type	Ex e II T3 Gb	Reinforce components that do not generate arcs under normal operating conditions to prevent the generation of dangerous high temperatures and electric sparks	Zone 1, Zone 2 areas, junction boxes, lamps
Intrinsically safe type (associated equipment)	Ex ia IIC T4 Ga	By limiting the energy of the circuit, it is ensured that it is insufficient to ignite explosive gases in any fault state	Zone 0, Zone 1 zones, controlled by instrument signals
