Know more about Cable Gland Chart Size for better choice!

Many people get confused with the chart sizes and the proper selection for the cable gland. So to make it more understandable and easy, we have provided you with the Cable gland chart size for better understanding. Here in this blog, we have tried to solve your all doubt about making a decision regarding cable gland chart size.

What is a cable gland?

A Cable Gland is described as a mechanical cable entry module. Usually, they are used to secure the electrical cables which are used in the long-lasting connections, unlike household plugins that are disconnected quickly. Most industries make use of electrical equipment to a certain extent by using cable glands. Cable glands are available in different types and sizes and are accordingly used in different conditions and applications.

Usage of cable gland:

Mostly the cable gland is used for two purposes: Connection Protection and Strain Relief. Connection Protection: With the help of cable glands it makes sure that the outside dust particles do not get accumulated on the electrical equipment. The outer cable sheath is protected by the cable gland protecting the wiring and electrical enclosure from environmental hazards such as dust, moisture, etc.

  • Strain Relief:
  • During the installation process, the cord grip secures the cable at a fixed angle. Due to this, the connection supplies strain relief and powerful opposition so as to prevent disconnection.

    A Cable Gland is made up of various brass, steel, plastics or aluminum material which is then used for glanding in many industries such as electrical power, control, data and telecommunication, instrumentation, etc. for electrical purposes. For proper usage of cable gland one must know cable gland chart size.

    So before you choose any cable gland, you need to first identify the conditions of the terminating end. Also, it is better to watch out for their standard ratings and protections for the right connection to establish. This is only viable when you are able to determine the suitable cable gland chart size as per your requirement.

    Let us know the steps involved in choosing the right cable gland chart size for your equipment. In the beginning you should verify your cable gland.

    Cable Gland Validation:

  • 1) Determine the type of cable, its design, and its material characteristics. Basically to know whether it is armored or not, single or multiple strands, etc.

  • Identify the following if the cable is armored:

    1. Specify the cable armor's type, dimensions, and composition.

    2. Inspect the cable armor's short circuit fault current rating.

    3. Calculate the inner bedding's diameter.

    4. The diameter of the lead covering should be measured.

    5. Verify the overall cable diameter's precise dimensions.

    6. Identify the environmental conditions and requirements, such as safeguards against the intrusion of water, dust, or gas.

    7. To avoid using joints made of different metals when using metal cable glands, take into account the material of the mating electrical equipment.

    8. Take into account whether the cable gland needs any protective plating.

    9. Determine the kind and dimensions of the cable entry hole on the corresponding electrical apparatus.

    10. Verify the site standards or the electrical equipment's ingress protection rating.

    11. Verify the type of cable gland needed for the application (single/double seal, material, etc.).

    12. Confirm that IP66 (or IP67/IP68) conditions call for the use of an entry thread seal.

    13. List the additional fixing components, such as locknuts, earth tags, shrouds, etc., that are necessary.

    Now that you are able to figure out all these steps, it will be easy for you to identify the correct cable gland and accessories needed for a useful connection. It becomes easy for you to proceed to the next step in knowing how to select a gland from the cable glands chart size.

    How to select gland from the Cable Glands Size Chart:

    Now let us check out how to select a cable gland from the cable glands size chart. As shown in the image, we have a size chart for standard cable glands. The nominal cable gland size is determined by the cable's overall diameter, armour diameter, and cable over sheath thickness.

    1. In the table you will see the cable glands size chart.

    2. The values in the rows represent the cross-sectional area (mm2) of the cable, and those in the columns represent the number of cable cores.

    3. Choose your cable size from the values in the rows.

    4. After that, count the number of cores in the cable using the columns that list them.

    5. The corresponding cell or box that matches the two aforementioned values displays the cable gland size that is suitable for the cable.

    For instance, we determine that the appropriate cable gland size is 25 for a 16mm² cable with 4 cores, similarly for a 95mm² cable with 3 cores the perfect cable gland size would be 40. The cable gland can accommodate a variety of cable diameters, and the choice of a specific type of cable gland is made using the provided datasheet or catalog.
