  1. Cable Gland Size Chart Armoured and Double Compression Gland Selecting the correct cable gland size chart is one of the most important steps in any electrical installation. A cable gland acts as the entry point for cables into equipment, ensuring safety, sealing, and mechanical protection. If the wrong gland size is chosen, it can lead to poor connections, water ingress, or even electrical hazards. In this guide, we will cover everything you need to know about cable gland size, including: ●Standard cable gland size chart in mm ●Detailed armoured cable gland size chart and unarmoured cable gland size chart ●Reference for double compression cable gland size chart ●Special case for 3.5 core 300 sq mm cable gland size ●Downloadable electrical cable gland size chart PDF for quick access

  2. Whether you are working with single compression, double compression, armoured, or unarmoured cables, this detailed blog will help you select the right cable gland type and size for your project. Cable Gland Size A cable gland size refers to the diameter range of cable that a gland can securely grip and seal. The right size ensures: ●Mechanical protection – prevents cable damage due to pull or twist. ●Environmental sealing – avoids dust, water, and gas entering equipment. ●Electrical safety – maintains proper earthing and shielding in armoured cables. Cable glands are generally specified in millimeters (mm) and linked to the outer diameter (OD) of the cable. For example, if a cable has an OD of 20 mm, you must select a cable gland size that covers the 18–22 mm range. Incorrect selection of a cable gland size can result in loose fitting, poor sealing, or even electrical faults. That’s why engineers always refer to a cable gland size chart before finalizing installations. Cable Gland Type and Size When selecting the correct cable gland type and size, it’s important to consider the application, cable construction, and environment. Different cable gland types are designed for specific uses such as indoor, outdoor, hazardous areas, and flameproof installations. Here are the most common cable gland types: Single Compression Cable Glands ●Used mainly for unarmoured cables.

  3. ●Provides basic sealing and strain relief. ●Suitable for indoor and controlled environments. Double Compression Cable Glands ●Designed for armoured cables. ●Provides sealing at both the inner and outer sheath of the cable. ●Offers extra mechanical strength and weatherproofing. ●Preferred for outdoor and hazardous areas. Brass Cable Glands ●Made of high-quality brass material for durability. ●Suitable for both armoured and unarmoured cables. ●Corrosion-resistant and used in industrial applications. Flameproof / A2F Cable Glands ●Specially designed for hazardous zones. ●Prevents flame propagation inside equipment. ●Commonly used for unarmoured cables in flameproof enclosures. Cable Gland Size Chart PDF For quick reference at project sites, many engineers prefer using a cable gland size chart PDF. Having it in a portable format helps during installation, inspection, or procurement. There are multiple variations available, including: ●Electrical cable gland size chart PDF – covers both armoured and unarmoured cable sizes.

  4. ●Double compression cable gland size chart PDF – for hazardous areas, outdoor installations, and heavy-duty applications. ●Armoured cable gland size chart PDF – for armored cables with metallic sheathing. You can also download the detailed version for offline use, making it easier to select the correct cable gland size without guesswork. Cable Gland Size Chart Types / Series Cable glands are classified by whether the cable is unarmoured or armoured. Each category has its own series, size charts, and clamping ranges. Cable Gland Size Chart for Unarmoured Cable :

  5. For unarmoured cables, glands are usually single compression or flameproof A2F type. These glands provide sealing but do not require gripping metallic armour. A2F Single Compression Cable Gland Size Chart The A2F type is a flameproof gland suitable for unarmoured cables. It ensures safe entry of cables in hazardous zones.

  6. Cable Gland Size Chart Series SCU, SCUB, DCU, DCUB – Size & Clamping Range The SCU, SCUB, DCU, and DCUB series are specifically designed for unarmoured cables, each offering different levels of sealing and mechanical strength.

  7. Cable Gland Size Chart for Armoured Cable

  8. For armoured cables, double compression glands are the standard choice.

  9. These glands grip both the inner and outer sheath of the cable, ensuring excellent strength and environmental protection. Double Compression Cable Gland Size Chart & Armoured Cable Clamping Range For armoured cables, double compression glands are the standard choice.

  10. These glands grip both the inner and outer sheath of the cable, ensuring excellent strength and environmental protection. Cable Gland Size Chart Series DCA, DCAB, SCA, SCAB – Size Section Chart

  11. These gland series are widely used for different armoured cable applications and provide secure sealing as per industry standards. 3.5 Core 300 sq mm Cable Gland Size One of the most common queries in industrial projects is the correct cable gland size for 3.5 core 300 sq mm cable. Since this is a heavy-duty power cable, it requires a gland that can handle a large outer diameter and provide maximum mechanical strength. For a 3.5 core 300 sq mm cable, the recommended gland is usually a double compression armoured cable gland, as it ensures proper clamping on both the inner and outer sheaths. Typical specifications: ●Cable Type: 3.5 Core, 300 sq mm ●Recommended Gland Type: Double Compression (Armoured) ●Clamping Range: Matches OD of approx. 55–65 mm (varies by manufacturer) ●Thread Size: Generally M75 or equivalent Since cable manufacturers may have slight variations in OD, always cross- check with the armoured cable gland size chart provided by the gland supplier before installation. Conclusion electing the right cable gland size chart is essential for safe and reliable electrical installations. From small indoor connections to large industrial power cables, the correct gland ensures sealing, mechanical strength, and long-term durability. In this blog, we explored: ●Standard cable gland size in mm ●Downloadable electrical cable gland size chart PDF ●Detailed armoured cable gland size chart and unarmoured cable gland size chart

  12. ●Specialized references like the double compression cable gland size chart and the 3.5 core 300 sq mm cable gland size By using the proper cable gland type and size, you can avoid common problems such as loose fittings, water ingress, or electrical faults. Always cross-check with the latest cable gland size charts (PDF or manufacturer images) before installation.
