In industrial electrical installations, ensuring a tight seal and secure cable entry is crucial. This is where the Double Compressor Gland comes into play. Specially designed for armored cables, this gland type offers superior sealing and mechanical grip. In this blog, we'll explain what a double compressor gland is, how it works, and where it’s most commonly used.
What is a Double Compressor Gland?
A double compressor gland is a type of cable gland designed to seal and hold armored cables. It contains two compression points:
One for the inner sheath of the cable.
Another for the outer sheath.
This dual compression ensures extra safety and environmental sealing—making it suitable for harsh industrial environments.
Key Features of Double Compressor Gland
Dual sealing for enhanced protection
Suitable for indoor and outdoor use
Provides excellent strain relief
Available in brass, nickel-plated brass, and stainless steel
Supports IP66/IP68-rated sealing
Compatible with SWA (Steel Wire Armored) cables
Applications of Double Compressor Glands
Double compressor glands are widely used in:
Power distribution systems
Oil and gas industries
Petrochemical plants
Heavy machinery control panels
Hazardous and flameproof areas (when certified)
Benefits of Using a Double Compressor Gland
Enhanced Sealing: Two compression points reduce the risk of water, dust, or gas entry.
Mechanical Strength: Withstands cable movement and external force.
Electrical Continuity: Ensures proper earthing in armored cable setups.
Long-Term Reliability: Less risk of loosening over time.
Installation Tips
Always check the cable size and match with the gland size.
Tighten both compression seals firmly for effective protection.
Use flameproof or explosion-proof certified glands in hazardous areas.
Why Double Compressor Glands Are Preferred in Industry
Compared to single compression glands, double compressor glands offer a higher degree of safety and reliability. Especially in critical environments where performance and protection cannot be compromised, they are a preferred choice by engineers and electricians.
Conclusion
The double compressor gland is an essential component in armored cable installations, offering high-level sealing, strain relief, and environmental protection. For industrial settings where durability and safety are paramount, investing in the right cable gland can make all the difference. Always ensure you're using quality-certified glands that meet your application’s requirements.
