A Safety Protection Expert Designed for Extreme Environments
Military-grade Sealing Protection (IP67)
- Fully Sealed: Blocks dust completely to keep the equipment clean.
- Waterproof: Handles short-term immersion in water, like heavy rain or floods.
- Materials: Uses EPDM silicone rubber for durability and temperature resistance.
- Uses: Works well in tough places like coasts, deserts, and wet areas.
Super Anti-Pollution Capability (Class E/Level IV)
- Industry Leading: Effectively handles industrial dust, salt spray, and chemical pollutants.
- Innovative Design: Nano-coating technology enhances self-cleaning efficiency by 40%.
- User Value: Reduces maintenance frequency by 80% and extends equipment lifespan.
Smart Diversion and Drainage System
- Biomimetic Diversion Channel Design: Rapid drainage to prevent water accumulation and corrosion.
- Self-Cleaning Structure: Prevents accumulation of bird droppings and fallen leaves, inhibiting microbial growth.
- Data Support: Laboratory simulations show no corrosion after 20 years of acid rain exposure.
Dual Explosion-Proof Protection
- Independent sealed chamber to isolate electric arcs from the external environment.
- Intelligent pressure relief channel for directional release of overpressure to prevent explosions.
- Technical Highlight: Verified through 100,000 pressure cycle tests.
