Cable Glands

More Information about Cable Glands

In addition to providing strain relief for cables, these components offer sealing properties to protect against elements like dust and dirt. This makes them useful for a range of industries, including telecommunications and various types of electrical equipment and systems.

Different gland types are designed to work with a specific diameter and type of cable. The diameters range widely, accommodating everything from slender wire to thick, armored cable. Specialized types, like cord grips, provide an extra layer of strain relief, ensuring that the cable doesn't pull out from the enclosure. Also, the glands often come with accessories like hexagonal locknuts for added security.

The type of sealing also varies, depending on the specific requirements. Some cable glands are designed to offer a high level of sealing, particularly suitable for hazardous areas or environments that demand a robust seal.

Split Cable Glands

Split cable glands serve as a secure and reliable method for routing pre-terminated cables and wires through an enclosure, panel, or bulkhead.

Unlike traditional cable glands that require the cable to be inserted from one end, split cable glands have a split design that allows them to be installed around pre-terminated cables without the need for cutting or splicing. These cable glands consist of three parts (two gland halves and a split sealing grommet). This makes them ideal for retrofitting or upgrading existing installations where cables are already terminated and cannot be easily removed.

FAQs

What cable type can be used with plastic glands?

Plastic cable glands can be used with a wide range of cable types, including PVC, rubber, and nylon cables. They are commonly used in indoor applications where the cable is not exposed to extreme temperatures or harsh environmental conditions.

Maintaining NEMA 4 Rating When Making Enclosure Penetrations

Cutouts are very common when modifying enclosures for push buttons, indication lights, conduit entries or mounting hardware. Cutting into an enclosure runs the risk of eliminating the protective nature of the NEMA rated attributes. Proper steps must be followed in order to preserve the NEMA rating of an enclosure.

Devices mounted to the enclosure must have the same NEMA rating as the enclosure

 This means that if the devices are installed to the manufacturer's specifications, they will be able to maintain the NEMA rating of the enclosure. 

Water tight conduit hubs must be used when running wire through a cutout in an enclosure

 There are many different types of conduit hubs that are used to secure conduit to an enclosure. However, only certain conduit hubs are rated for a watertight seal. By using water tight hubs, the NEMA rating of the enclosure is maintained.

Bonded washers are necessary when mounting hardware to an enclosure

 If standard mounting hardware is used, the NEMA rating of the enclosure will no longer be maintained. Bonded washers have rubber gaskets that make a watertight seal around the drilled hole. It is also important to make sure the material used for the bonded washer matches the material of the enclosure. Stainless steel enclosures require stainless steel bonded washers.
