In any electrical network, providing a strong and safe connection between cables and equipment is paramount. That is where brass cable glands are essential. These little but critical devices are employed to secure, seal, and join the end of an electrical cable to the device it is powering. But what are brass cable glands, and how do they operate? Let's find out.
What Are Brass Cable Glands?
Brass cable glands are mechanical parts that are intended to hold in place the termination of a cable onto equipment like junction boxes, panels, or motors. Produced using high-quality brass, they are strong, resistant to corrosion, and conductive. They find wide use in industrial, commercial, and outdoor electrical connections because they can resist harsh conditions and are extremely durable.
Brass is usually selected based on its durability against wear and tear, conductivity, and magnetic non-conductivity. A number of brass cable glands also have nickel plating or other protective coatings for increased performance and durability.
Major Roles of Brass Cable Glands
Brass cable glands are used for various purposes in an electrical system:
Securing of Cable: They securely fix the cable so it cannot move freely and loosen up or get damaged.
Strain Relief: They shield the cable from mechanical stress, thereby ensuring a good electrical connection.
Sealing and Protection: They seal the cable entry point, excluding dust, dirt, moisture, and other contaminants from the enclosure.
Grounding and Bonding: In some applications, brass cable glands also ensure proper earthing and grounding, particularly in armoured cable systems.
How Do Brass Cable Glands Work?
Brass cable glands function through a compression process. This is a brief overview of what happens:
Insertion of the Cable: The cable is threaded through the body of the gland.
Gland Tightening: When the nut on the gland is tightened, it squeezes an internal seal component (commonly rubber or a similar material) around the cable.
Seal and Grip: This compressing action generates a tight seal around the cable and also secures it in place.
Enclosure Protection: The threaded end of the gland is plugged into an electric enclosure so that no foreign particle or fluid gets in through the cable entry.
Through this sealing and cabling mechanism, not just ingress is inhibited but also, the cable can't be removed or damaged easily.
Applications for Brass Cable Glands
Brass cable glands are extensively employed in:
Industrial machinery
Control panels
Lighting outdoors
Power distribution panels
Renewable energy units
Marine and offshore fittings
Their high resistance to corrosion and wear makes them ideal for demanding applications where longevity and safety are essential.
