Functional Features
- Safe cable connection and line branching in explosive hazardous areas
- Mechanical protection and dust-proof, water-proof for internal circuits
- Explosion-proof flame-retardant structure, prevent internal explosion from spreading to the external environment
- Stable electrical connection, anti-loosening and anti-vibration
Performance Parameters
- Rated Current: Standard load current matching the model
- Explosion-proof Clearance: Comply with international explosion-proof standard clearance requirements
- Shell Compressive Strength: Withstand internal explosion impact without rupture
- Insulation Performance: Long-term stable insulation under rated voltage
- Anti-aging Performance: Shell material resistant to ultraviolet and chemical aging
Material Composition
- Main shell: Cast aluminum alloy for explosion-proof use (special anti-spark treatment)
- Internal terminal parts: Brass with anti-corrosion coating
- Sealing parts: Nitrile rubber / fluororubber explosion-proof sealing ring
- Fasteners: Stainless steel anti-rust bolts
Structural Characteristics
- Integral cast explosion-proof shell, thickened wall structure
- Multi-channel cable entry ports with sealed cable glands
- Split upper and lower shell structure, convenient for wiring and maintenance
- All joints adopt labyrinth explosion-proof structure + double sealing
Working Principle
After the cable enters the shell through the sealed cable gland, it is connected to the internal terminal to complete circuit conduction. When internal short circuit or spark occurs accidentally, the thickened explosion-proof shell and labyrinth structure limit the explosion energy inside the cavity, block the flame and high-temperature gas from spreading outwards, so as to avoid triggering external flammable gas or dust explosion.
Advantage Highlights
