Double Compression (DC) Cable Glands are heavy-duty, industrial-grade connectors used to securely seal and terminate armored cables at both the inner and outer sheaths. They provide superior, IP65-IP68 rated protection against dust, moisture, and corrosion while offering high-strain relief and mechanical strength. These glands are typically made of nickel-plated brass and are essential for safety in hazardous, flameproof, and explosive atmospheres.
Key Features and Benefits
- Double Sealing Mechanism: Compresses both the inner insulation and outer sheath for maximum environmental protection.
- Flameproof & Hazardous Area Use: Suitable for dangerous environments like oil and gas, petrochemical, and mining, offering explosion-proof capabilities.
- Robust Construction: Manufactured from nickel-plated brass to resist corrosion and handle high mechanical stress.
- Increased Safety: Provides excellent armor wire termination and electrical continuity.
- Versatility: Available in various sizes for armored cables and can be used with PVC shrouds for added corrosion protection.
- Brass Body/Gland Barrel: Main housing.
- Armour Clamp and Ring: Secures the cable armor.
- Inner and Outer Seals: Two-stage sealing for protection.
- Check Nut and Washers: Ensures a secure, leak-proof fit.
These glands are often compared to single compression glands, offering, on average, a 30% longer structure for better sealing and retention.
