Cable Gland Chart Size in Every Sizes

Choosing the correct cable gland size can be confusing for many. To simplify this process,>Pioneer Powers will provide a comprehensive guide to help you understand cable gland chart sizes and make informed decisions. This blog aims to clear all doubts regarding cable gland size selection.

What is a cable gland?

A cable gland is a mechanical cable entry device used to secure electrical cables, especially in permanent installations. Unlike household plugs that can be disconnected quickly, cable glands are designed for long-lasting connections. They are widely used in various industries, such as electrical power, control, data and telecommunication, and instrumentation, where secure and reliable cable connections are crucial. Cable glands come in different types and sizes to suit various applications and environmental conditions.

Usage of cable gland:

Cable glands primarily serve two purposes: Connection Protection and Strain Relief.

• Connection Protection: Cable glands prevent dust, moisture, and other environmental hazards from entering electrical equipment. They protect the outer cable sheath, ensuring the wiring and electrical enclosure remain intact and safe.
• Strain Relief: During installation, cable glands secure the cable at a fixed angle, providing strain relief and preventing disconnection due to tension or movement.

Cable glands can be made from brass, steel, plastic, or aluminum and are used across various industries for securing electrical connections. Understanding the appropriate cable gland chart size is essential for their proper use.

Steps to Choose the Right Cable Gland Size

Cable Gland Validation:

• Determine the type of cable, its design, and material characteristics (e.g., armored or unarmored, single or multiple strands).
• If the cable is armored, specify the armor's type, dimensions, and composition, inspect its short circuit fault current rating, measure the inner bedding's diameter, the lead covering's diameter, and the overall cable diameter.
• Identify environmental conditions and requirements (e.g., protection against water, dust, gas).
• Consider the material of the mating electrical equipment to avoid using joints made of different metals.
• Determine if any protective plating is needed for the cable gland.
• Verify the cable entry hole's type and dimensions on the corresponding electrical apparatus.
• Check the site standards or the ingress protection rating of the electrical equipment.
• Confirm the type of cable gland needed (e.g., single/double seal, material).
• Ensure IP66 (or IP67/IP68) conditions call for an entry thread seal.
• List additional fixing components needed, such as locknuts, earth tags, shrouds, etc
• Verify the cable entry hole's type and dimensions on the corresponding electrical apparatus.
• Verify the cable entry hole's type and dimensions on the corresponding electrical apparatus.



By following these steps, you can accurately identify the correct cable gland and necessary accessories for a secure connection.

How to select gland from the Cable Glands Size Chart:





The cable gland size chart helps determine the nominal cable gland size based on the cable's overall diameter, armor diameter, and cable sheath thickness.

• The rows in the table represent the cross-sectional area (mm²) of the cable.
• The columns indicate the number of cable cores.
• Find your cable size in the rows and count the number of cores using the columns. The corresponding cell will show the suitable cable gland size.

For example, a 16mm² cable with 4 cores requires a cable gland size of 25, while a 95mm² cable with 3 cores requires a size of 40.

Installation and Maintenance of Cable Glands through Cable Gland Chart Size

Before installation, ensure you have all necessary accessories, such as earth tags, locknuts, PVC shrouds, and measuring tools. Follow these steps:

1. Preparation: Wear PPE and gather tools like digital measuring devices, dedicated spanners, electrical scissors, armor-forming tools, hacksaws, and safety knives.
2. Installation:
• Turn off circuits before working with cable glands to avoid electrical hazards.
• Avoid mixing components from different manufacturers.
• Detach the nut from the cable gland, peel the outer sheath to the appropriate length, and lay the cable evenly around the gland.
• Insert the gland into the cable and secure it with a spanner.

Proper installation ensures a secure connection and prevents damage to electrical equipment.

People Also Ask (FAQs):

1. How to choose cable gland size?

Only these few steps are to be taken care of while choosing cable gland size chart i.e check what type of cable you want according to that see what is your size requirement and then finally you can find the best fit cable gland.



2. How to calculate gland size for cable?

Identify what type of cable you might use armoured or unarmoured. Depending on that check the size and material of the required cable mentioned in its description. Finally, don¹t miss out on identifying the overall diameter of the cable (A or B) which will be specified in the product table. Just as mentioned in the example given above.



3. How many types of cable glands are there?

There are four types of cable glands. We provide A1/A2 Industrial cable gland, CW Industrial cable gland, BW Industrial cable gland also Single and Double compression cable glands.



4. What is a cable gland chart size, and why is it important?

Cable gland chart size is a table chart that helps to understand the dimensions of the overall cable gland. It is important because by referring to the cable gland chart size you can easily know the diameter and thickness of the cable gland and buy accordingly.



5. How do I choose the right cable gland size for my application?

You simply have to refer to the cable gland chart size for instance if your cable gland is of polycab then make sure you refer to the polycab cable gland size chart. Similarly, based on the types of cable glands refer to cable gland chart size.



6. What are some common materials used in cable glands?

In cable glands accessories like earth tags, locknuts, PVC shrouds and PVC-covered copper or aluminum tape/strips can be used while installing.



7. What is the difference between a cable gland and a cable connector?

Only technical distinction is made in terminology as cable gland is often referred as cable connector, both functions the same.



8. What are some key considerations when installing a cable gland?

Make sure you don¹t lose the fittings while installing as people tend to miss that thing and forget to recheck it.



9. How do I maintain and inspect my cable glands?

Once the installation process is finished you can have an inspection when you think there is any electrical damage done. Make sure you inspect sealing performance, armour clamping, and reliable earth continuity.
