All About Waterproof Cable Glands

Waterproof cable glands are used to maintain the cutouts of your enclosure by keeping it waterproof. Usually, cable glands are used in NEMA 4X or IP rating. In this article, we will discuss what is a waterproof cable gland and how it can affect the features of your enclosures.

What is a Waterproof Cable Gland?

Waterproof cable glands are a device that is used to connect cables and wires inside the electrical enclosure. This helps in the maintenance of seal that is located in the entrance of cable and wires of the enclosure by keeping it watertight. Cable glands comes in either of these two compositions: it can either has a separate gasket and cable seal, or these two can be integrated together into the body of the gland. Usually, the body of the cable gland is composed of a body and a nut. After glands are assembled, it is not installed within the circular cutout located in the enclosure. The end result will be the gland will capture the wall of the enclosure located between the body and nut creating watertight seal to avoid ingress.

Cable glands can come in different types, materials used, and sizes. In this article we will discuss the features of the cable glands, the material that can be used to manufacture it and the application of waterproof cable glands. These can be found in the market today:

One of the features of waterproof cable glands is that it can withstand harsh environments and it can also be explosion-proof and can inhibit flames. It can also offer UV stabilization and EMI/RFI shielding.

Waterproof cable glands are usually manufactured using aluminum, plastic, nylon, stainless steel and brass. The material will be used to make cable glands will largely depend on the application and type of electrical enclosure that will be used. For example, to avoid corrosion in cable glands steels such as aluminum and stainless steel can be used.

The usual applications of cable glands can vary depending on the need of the application. The applications may vary depending on the industry where it will be used. Cable glands can be customized to fit the need of the company because it can have custom cutouts to accommodate varying size of the cables. There are several industries where you can find waterproof cable glands such as: waste water treatment plants, manufacturing plants, marine offshore companies and so much more.

How Waterproof Cable Glands Work?

Throughout several industries, waterproof cable glands are the best item to go to when engineers need cable wires entering the enclosure to be protected from water ingress, especially when they need the equipment inside the enclosure to be protected. It can protect the enclosure from any type of ingress – water, dust, and other foreign materials. Engineers can specify if an enclosure needs waterproof cable glands. A hole is needed to add on the enclosure. Then, engineers will assemble the waterproof cable gland together. The nut and gasket are placed inside the electrical enclosure and the body goes out exteriorly from the enclosure. After this, the cable is threaded through and to seal it tight, screw the nut and body together to create a waterproof tight seal.
