How to Install a Multi Hole Cable Glands
If you need to terminate the ends of multiple cables all at once, a multi hole cable gland is a useful accessory. It lets you do so while providing your cables with protection from moisture, dirt, dust and other contaminants. It also provides them with strain relief, preventing excessive amounts of stress from being placed on their connections.
A multi hole cable gland is a series of threaded parts that fit together to grip the cable and secure it to a panel or enclosure. They come in different sizes, and are used in a wide variety of applications. The number of cable glands you need will depend on the number and size of wires you are connecting.
There are various types of multi-hole cable glands available, including double compression glands and PG or CW type steel wire armour glands. Choosing the right one for your cable will ensure that you get the best performance and protection from environmental threats. It will also help you save time and effort since you won’t have to do the installation process repeatedly.
Before you purchase a multi-hole cable gland, you must first know the diameter of the cables you want to connect. You can do this by checking the data sheet or measuring them yourself. You should also determine if the cables are armored or unarmored. An armored cable is much thicker than an unarmored one, so it needs more support. It can also be exposed to dangerous environmental contaminants, such as gas, dust and moisture.
The next step is to choose the proper size of the gland. This will be based on the diameter of the cable, as well as its thickness and outer diameter. You can also use the data sheet to find out the recommended gland size for your cables.
Once you have selected the correct gland for your cable, you can install it. First, you should cut the cover of the gland. This is necessary to expose the galvanized steel wires inside. Then, you can insert the cable and then put on the rubber sealing ring, nozzle nut and the collar onto the cable. You can then use spanners to tighten the parts of the gland.
You should always inspect your multi-hole cable gland regularly for signs of wear and tear. Once they begin to wear out, they will no longer provide the same levels of protection as they did when they were new. If you notice that they are not performing as they should, it is best to replace them. Otherwise, they may leak contaminants into your cable’s connections, causing them to fail.
