Selecting the correct cable gland size is essential when working with SWA (Steel Wire Armoured) and armoured cable systems. Whether you are installing a 4 core armoured cable, upgrading industrial wiring, or comparing armoured cable price and performance, the right gland size ensures proper sealing, grounding, and long-term safety.
Most professionals search for a cable gland size chart to simplify selection, but choosing the correct gland for an armoured cable involves more than just size matching. Factors like cable diameter, armour type, environmental conditions, and application all play a critical role. In this guide, you’ll get a complete, easy-to-use size chart along with expert tips to make the right decision.
What is SWA & Armoured Cable?
SWA (Steel Wire Armoured) cable is a strong type of armoured cable used for heavy-duty electrical connections. It has a layer of steel wires that protects the cable from physical damage, making it ideal for industrial and outdoor use.
These cables are commonly used in power cable installations where safety, durability, and long life are important.
| Feature | Description |
|---|---|
| Cable Type | SWA (Steel Wire Armoured) Cable |
| Protection | Steel wire armour for mechanical protection |
| Usage | Industrial, outdoor & underground applications |
| Strength | High durability for harsh environments |
| Common Types | 2 core, 3 core, 4 core armoured cable |
| Application | Power distribution & heavy electrical systems |
Why Cable Gland Size is Important
Selecting the correct cable gland size for armoured cable is one of the most critical steps in any electrical installation. A properly sized cable gland not only secures the cable but also ensures long-term safety, performance, and reliability especially in demanding SWA and power cable applications.
When the right size is used, the cable gland creates a tight seal around the cable, preventing external elements from entering and maintaining the required IP protection rating. At the same time, it provides a strong mechanical grip that holds the cable firmly in place, even in high-vibration or industrial environments.
For SWA (Steel Wire Armoured) cables, correct sizing is even more important because it ensures proper earthing. The gland must securely clamp the armour layer to maintain electrical continuity and safety.
- Ensures complete sealing against dust, water, and moisture
- Provides strong mechanical grip to avoid cable pull-out
- Maintains effective earthing for armoured cables
- Protects cables from vibration, movement, and stress
- Increases overall installation lifespan and reliability
Selecting the right gland is just as important as choosing the right cable. That’s where the cable gland size chart and cable gland selection chart come in. These charts act as quick references to match the outer diameter of a cable with the correct gland size.
Types of Cable Glands for SWA Cables
| Cable Gland Type | Best Use Case | Key Features | Suitability for SWA |
|---|---|---|---|
| Double Compression Cable Glands | Heavy-duty & armoured cables | Dual sealing, strong grip, proper earthing | Highly Recommended |
| Single Compression Glands | Light-duty & unarmoured cables | Basic sealing, simple installation | Not Recommended |
| Brass Cable Glands | Industrial & outdoor environments | Corrosion resistant, durable, long lifespan | Suitable |

Selecting the right gland is just as important as choosing the right cable. That’s where the cable gland size chart and cable gland selection chart come in. These charts act as quick references to match the outer diameter of a cable with the correct gland size.
Why use a Cable Gland Size Chart?
Selecting the right gland is just as important as choosing the right cable. That’s where the cable gland size chart and cable gland selection chart come in. These charts act as quick references to match the outer diameter of a cable with the correct gland size.
-
Ensures a tight and reliable seal
-
Prevents water, dust, or gas entry
-
Avoids loose fittings that may cause cable damage
-
Simplifies installation for engineers and electricians
A cable gland selection chart also highlights which gland type is suitable for armoured, unarmoured, or flexible cables. For example, a brass cable gland is often selected for armoured cables in oil & gas industries, while a waterproof cable gland is chosen for outdoor solar or marine applications.
