Cable Glands

Cable glands are connectors used to secure and seal the ends of cables to terminals, enclosures or electrical equipment. They can be used on all types of cables including: telecommunication, data and electrical. Cable glands are designed to attach cables in place and prevent them from being twisted or pulled out. They provide additional support against cable strain and prevent dirt, dust and moisture from entering.
There are two main types of cable glands. Singe compression cable glands are typically used for smaller installations within buildings and double compression cable glands which are used in factories and power plants where stronger seals are required. Double compression glands have double sealing and double compression at the cable core and on the outer sheathing.
Cable glands are generally made of metals or plastics. Metallic cable glands can be made of stainless steel, aluminum or nickel-plated brass. They provide long-term durability, rigid stability and thermal and electrical conductivity. They are ideal for applications where mechanical strength and chemical stability are required. Plastic cable glands can be made of polyamide or nylon. They are resistant to grease, weak acids and salt water. They are an ideal choice for industries with corrosive environments.

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.
