What Are BW Type Cable Glands and How Do the 2 Part and 4PT Variants Differ?
In modern electrical and power infrastructure, cable glands are essential for ensuring safe, secure, and efficient cable management. Among the many types available, the BW Cable Gland stands out as a trusted solution for armoured cable terminations—especially in indoor installations. At Triera Metals, we specialize in delivering high-quality electrical accessories, including BW type cable glands in both 2 Part and 4PT variants, designed to meet the exacting demands of industrial environments.
In this blog, we explain what BW cable glands are, explore the differences between the 2 Part and 4PT versions, and guide you on choosing the right type for your specific application.
Understanding the BW Cable Gland
A BW cable gland is a brass-based cable termination accessory used primarily with SWA (Steel Wire Armoured) cables. Designed for indoor applications, this type of gland provides:
- Mechanical retention of the cable
- Electrical continuity between the armour and the gland body
- A secure entry point into electrical enclosures
At Triera Metals, our BW cable glands are manufactured from high-grade brass and are available with optional nickel plating to increase corrosion resistance. Our products are meticulously crafted to meet industry standards and are built for dependable, long-term performance.
Key Features and Advantages
BW cable glands find extensive application in sectors such as power transmission, industrial automation, HVAC systems, and large-scale infrastructure projects. Some of their primary benefits include:
- Robust Construction: Keeps cables firmly in place, even under conditions involving heavy vibration.
- Earthing Performance: Provides a reliable earth path for the cable armour.
- Ease of Installation: BW glands are designed for quick, tool-assisted installation.
- Versatility: Suitable for use in switchgear panels, distribution boards, and electrical machinery.
2 Part vs. 4PT BW Cable Glands: What’s the Difference?
Durable Build: Maintains cable stability and prevents loosening in environments with constant or intense vibration. Here’s how they compare:
- 2 Part BW Cable Glands

- Ideal for use in switchboards and internal junction boxes
- Use Cases: Commercial buildings, control panels, basic infrastructure installations.
- 4PT BW Cable Glands
Our 4PT BW cable glands are an enhanced version designed for more demanding environments. These typically include: Gland body, Compression nut, Earth tag, Locknut, (Often) a PVC shroud for additional sealing
Best suited for: Projects requiring superior electrical continuity and protection.
Advantages:
- Provides better strain relief and grounding
- Greater stability under mechanical stress
- Suitable for dusty or partially exposed areas when used with shrouds
- Use Cases: Industrial machinery, heavy-duty infrastructure, energy sector installations.
Choosing the Right BW Cable Gland for Your Project
When selecting between the 2 Part and 4PT cable glands from Triera Metals, consider the following factors:
- Installation environment: Choose 4PT for harsher conditions or where additional grounding and sealing are required.
- Cable specifications: Ensure compatibility with your cable diameter and armouring.
- Compliance needs: Both variants meet general compliance standards, but 4PT glands offer an added layer of protection and performance.
