How do cable glands work?
The cable gland is a complex component consisting of a central housing, lock nut with washer and seal, connecting cone, compression/packing nut, two-part housing (in some models), electrical grounding tab, insulator, and rubber seal. Once the cable has been threaded through the cable gland and secured in place, it creates an airtight seal that protects the cable from external elements such as moisture or dirt.
The most common uses of cable glands
Cable glands are sometimes called collets, mechanical cable entries, cable connectors, or cable accessories and provide a protective enclosure around the ends of cables to secure connections and prevent damage or strain.
They provide a way to connect and disconnect wires and a way to protect them from wear and tear. There are many different types of cable glands, each with a specific purpose. These high-security sealing and termination devices are most commonly used in the following applications:
Cables laid outdoors must be protected from rain and other adverse weather conditions. To ensure maximum protection, appropriate environmental protection measures should be taken.
Damage and corrosion must be prevented when electrical equipment and cables are used in offshore environments where they may be exposed to salt water. Appropriate protective measures should be taken to ensure that electrical connections remain functional and safe. Such measures include sealing, capping, and waterproofing of all applicable components.
In hazardous, explosive, or dangerous industrial environments, extra care must be taken. These areas require specific safety procedures to ensure the safety of personnel and equipment. Extra care must be taken to ensure safe and secure operations in these spaces.
In dusty industrial environments, electrical equipment must be kept away from them for safety reasons. In these situations, keeping a safe distance is the best way to protect yourself and those around you.
It is important to take protective measures when unarmored or unprotected cables may come into contact with hazardous or corrosive materials. Proper protective structures should be implemented to keep these valuable assets safe.
If your application involves any of these risks or requirements, it is important to consider the various cable gland types and choose the one that provides the appropriate level of safety and protection. For example, you may need a watertight cable gland to prevent water ingress or a metallic cable gland made of brass, aluminum, or steel for robust performance.
