2. Features
1. Upgraded reinforced multi-sealing structure with optional silicone seal material delivers IP66–IP68-rated waterproof and dustproof performance; while the inner cable sheath is not explosion-proof sealed (no explosion-proof performance for cable entry), the gland body carries Ex db ⅡC Gb / Ex eb ⅡC Gb / Ex tb ⅢC Db certification, providing robust mechanical and environmental protection for non-armored cable entry in hazardous locations.
2. Corrosion and salt-spray resistant body materials (nickel-plated brass, SS304, SS316L) with PA6 anti-rotation washers deliver high mechanical strength, reliable cable retention, and excellent vibration and anti-loosening performance in demanding industrial conditions; multiple thread options (M, NPT, G, PG) support flexible wiring configurations across diverse installations.
3. Fully compatible with LD Electric explosion-proof enclosures and equipment for seamless integration; offers customizable specifications and materials to meet specific project requirements, with the upgraded reinforced design and anti-loosening functionality particularly suited for rail transit, offshore, and heavy-duty industrial environments where long-term cable retention and environmental sealing are essential — note that this series is intended for non-armored cables only and does not provide explosion-proof cable entry performance.
