Structural Characteristics
- Rectangular integral explosion-proof cavity structure
- Multiple cable inlet and outlet ports with independent sealing glands
- Internal fixed terminal row, orderly wiring layout
- Detachable upper cover, equipped with anti-loosening fasteners
Working Principle
The external cable enters the explosion-proof cavity through the sealed gland and is connected to the internal terminal row to realize circuit convergence and branching. When electric spark or local overheating occurs inside the cavity, the closed explosion-proof shell and labyrinth structure confine the danger inside the equipment, isolate the ignition source from the external flammable medium, and ensure the safety of the hazardous area.
Advantage Highlights
- Integrated multi-terminal design, realize centralized wiring and save on-site layout space
- High-strength explosion-proof and high-level protection, wide environmental adaptability
- Anti-corrosion shell treatment, long service life in chemical environment
- Standardized structure, convenient for batch installation and later maintenance
Applicable Industries
Oil field, natural gas station, petrochemical plant, chemical reaction workshop, fuel storage area, explosive dust production workshop
Model Series
