2. Features
1. Upgraded heavy-duty multi-sealing structure with double-seal design specifically for armored cable wiring ensures the inner cable sheath is sealed effectively, delivering IP66/IP67/IP68-rated explosion-proof, waterproof, and dustproof performance; Ex db ⅡC Gb / Ex eb ⅡC Gb / Ex tb ⅢC Db certification guarantees containment of internal ignition and prevention of flame propagation.
2. High mechanical strength body materials (nickel-plated brass, SS304, SS316L) with PA6 anti-rotation washers provide excellent corrosion and salt-spray resistance, reliable cable retention, and vibration resistance in demanding industrial conditions; multiple thread options (M, NPT, G, PG) support flexible wiring configurations.
3. Fully compatible with LD Electric explosion-proof enclosures and equipment for seamless integration; the double-seal structure with anti-loosening functionality ensures secure armored cable entry, offering customizable specifications and materials to meet specific project requirements across diverse on-site conditions including rail transit and offshore platforms.
