Typical Cable Glands
The different components of a CW type Steel Wire Armour cable gland.
Examples include shrouded cable glands leading into a flow meter and split cable gland KVT for directing pre-terminated cables.
A cable gland, which is frequently referred to in the U.S. as a cord grip, cable strain relief, cable connector, or cable fitting, is a crucial device used to attach and secure the ends of electrical cables to various equipment.Types of cable gland provides strain relief and an appropriate connection method suited for the specific type and description of the cable involved. This includes mechanisms for establishing electrical connections with the cable's armor or braid, as well as any lead or aluminum sheaths, if applicable. Cable glands are typically utilized for cables with diameters ranging from 1 mm to 75 mm.
Cable glands are essentially mechanical devices for cable entry, used extensively across various industries, especially in electrical instrumentation and automation systems. They accommodate all types of electrical power, control, instrumentation, data, and telecommunications cables. Acting as sealing and termination devices, cable glands help maintain the characteristics of the enclosure through which the cable enters. These devices are constructed from various materials including plastics, steel, brass, and aluminum for industrial applications. To withstand water exposure, cable glands designed for such conditions often include synthetic rubber or other elastomeric seals. Certain types of cable gland may also play a role in preventing the infiltration of flammable gases into equipment enclosures, particularly for electrical equipment used in hazardous locations.
Despite the common terminology that refers to cable glands as "connectors," it is crucial to differentiate them from quick-disconnect, conducting electrical connectors.
For managing pre-terminated cables—those fitted with connectors—split cable glands prove to be an excellent option. These glands are composed of three parts: two halves and a split sealing grommet, fastened together with a hexagonal locknut, similar to conventional cable glands. With split cable glands, pre-assembled cables can be routed without needing to remove the plugs, achieving ingress protection ratings as high as IP66/IP68 and NEMA 4X.
Another alternative involves using split cable entry systems that typically consist of a robust frame accompanied by several sealing grommets, providing a mechanism to guide multiple pre-terminated cables through a single wall cut-out.

Understanding Cable Glands and Their Applications
Cable glands are essential components within electrical systems, offering vital protection and stability to cables across various environments. Their multifunctional nature includes sealing, securing cables, shielding against corrosion, and preventing the ingress of flammable gases.
The following sections highlight the primary functions and advantages of cable glands, contributing to the durability and reliability of your electrical installations:
Seal and Secure
Cable glands effectively seal cable ends, blocking moisture, dust, dirt, and other contaminants that can jeopardize electrical connections. This sealing capability is crucial for maintaining the overall integrity of the electrical system, particularly in challenging environments.
Protect Against Corrosion
By safeguarding sensitive electrical wiring from corrosive elements, cable glands significantly prolong the lifespan of cables while ensuring consistent performance. This protective feature is especially pertinent in industrial settings where cables may be exposed to harsh chemicals and environmental conditions.
Prevent Flammable Gas Ingress
In hazardous environments, cable glands serve to thwart the ingress of flammable gases, minimizing the risk of explosions or fires. This safety attribute is imperative for protecting both equipment and personnel.
Ensure Mechanical Stability
Cable glands offer mechanical support and strain relief, ensuring that cables remain securely connected to plugs, terminals, enclosures, or other electrical devices. This stability helps avoid accidental disconnections and diminishes the potential for cable damage.
