1. Aluminum alloy die-cast housing undergoes high-speed shot blasting followed by high-pressure electrostatic powder coating for corrosion resistance and aging resistance.
2. Stainless steel exposed fasteners provide superior corrosion resistance.
3. The LBZ series features two housing structures: fully flameproof and composite. Internally houses flameproof chamber-specific indicator lights, pushbuttons, universal changeover switches, instruments (other instruments can be installed per user requirements), potentiometers, etc. The LCZ series employs an increased safety enclosure structure, housing explosion-proof components such as indicator lights, pushbuttons, changeover switches, instruments, and potentiometers.
4. Increased safety terminal blocks from domestic or international renowned brands are used, enhancing product safety.
5. Explosion-proof components feature modular design for high interchangeability.
6. Diverse switch functions can be customized per user requirements; switch handles can be equipped with padlocks to prevent accidental operation.
7. Hinges can be added to the enclosure and cover as required, offering an aesthetically pleasing appearance and convenient maintenance access.
8. Cable routing (specify steel pipe routing if required).
1. Suitable for Zone 1 and Zone 2 locations in explosive gas environments;
2. Suitable for Class IIA, IIB, and IIC explosive gas environments;
3. Suitable for Zone 21 and Zone 22 locations in explosive dust environments;
4. Suitable for Class IIIA, IIIB, and IIC explosive dust environments;
5. Suitable for temperature classes T1 to T6;
6. Suitable for hazardous environments in petroleum extraction, refining, chemical processing, power generation, offshore oil platforms, oil tankers, painting, metalworking, and similar applications.
