CW cable gland is widely used for terminating armoured cables in indoor electrical installations where mechanical strength, cable retention, and earth continuity are essential. Known for their robust design, CW cable glands are a preferred choice in commercial and industrial wiring systems across global markets.

At Volt Metal Industries, we manufacture and export Brass CW Cable Glands designed for consistent performance, dimensional accuracy, and long service life.

What Is a CW Cable Gland?

A CW cable gland is a type of armoured cable gland used mainly with Steel Wire Armoured (SWA) cables. It provides:

• Secure clamping of the cable armour.
• Effective mechanical cable retention.
• Reliable earth continuity through armour clamping.
• Protection against cable pull-out and vibration.

CW glands are typically used in dry, indoor environments where high ingress protection is not the primary requirement.

Key Features of Brass CW Cable Glands:

• Designed specifically for armoured cables (SWA).
• Strong and durable brass construction.
• Accurate armour clamping using a cone and ring mechanism.
• Suitable for indoor electrical panels and enclosures.
• Compatible with multiple thread types (Metric, ET, NPT, PG).
• Long-lasting performance under mechanical stress.

Parts of a CW Cable Gland:

A standard Brass CW Gland consists of the following components:

1. Gland Body – Houses the internal components and mounts to the enclosure.
2. Armour Clamping Cone – Grips the cable armour securely.
3. Armour Clamping Ring – Supports uniform clamping around the armour.
4. Compression Nut – Applies compression to lock the armour.
5. Lock Nut – Secures the gland to the panel or enclosure.

Optional accessories include earth tags and PVC shrouds, depending on application requirements.

CW Cable Gland Size Selection (Overview):

CW cable gland sizing depends on:

• Overall diameter of the armoured cable.
• Armour thickness and wire size.
• Entry thread requirement of the enclosure.

A detailed CW cable gland size chart helps installers select the correct gland for a secure fit and proper armour termination.

Applications of CW Cable Glands:

CW cable glands are commonly used in:

• Electrical switchgear and control panels.
• Indoor industrial wiring systems.
• Commercial buildings.
• Power distribution boards.
• Machinery and equipment wiring.

They are especially suitable where mechanical protection and earthing are more critical than weatherproof sealing.

CW vs BW Cable Glands – Key Difference:

• CW Cable Gland: Designed mainly for indoor use; focuses on armour clamping and earth continuity.
• BW Cable Gland: Provides basic armour clamping but is generally used in less demanding applications.

For environments requiring environmental sealing or outdoor use, other gland types such as E1W or double compression glands are recommended.

Why Choose Brass CW Glands?

• Excellent mechanical strength.
• Good electrical conductivity for earthing.
• Corrosion resistance.
• Easy installation and long service life.

Brass CW glands remain a trusted choice for installers and EPC contractors worldwide.

CW Cable Gland Manufacturer, Supplier & Exporter – Volt Metal Industries:

Established in 1987, Volt Metal Industries is a manufacturer and exporter of Brass CW Cable Glands and cable gland accessories. We supply consistent-quality glands suitable for domestic and export markets, supporting bulk requirements and customised specifications.

Frequently Asked Questions (FAQs):

1. What is a CW cable gland used for? A CW cable gland is used for terminating armoured cables in indoor installations, providing mechanical retention and earth continuity through armour clamping.
2. Is a CW cable gland suitable for outdoor use? CW cable glands are primarily designed for indoor use. For outdoor or weather-exposed applications, weatherproof or double compression cable glands are recommended.
3. What cables are compatible with CW cable glands? CW glands are mainly used with Steel Wire Armoured (SWA) cables in low and medium-voltage installations.
4. How do I choose the correct CW cable gland size? Select the gland based on the overall cable diameter, armour thickness, and enclosure entry thread size. Referring to a CW cable gland size chart ensures correct selection.
5. Are Brass CW Glands better than other materials? Brass CW glands offer superior strength, conductivity, and durability compared to many alternative materials, making them ideal for industrial applications.
6. Do CW cable glands provide waterproof protection? No. CW cable glands are not designed to be weatherproof. They focus on armour clamping and earthing rather than ingress protection.
7. Can CW cable glands be supplied in bulk for export? Yes. Volt Metal Industries supplies CW cable glands in bulk quantities for export markets and large project requirements.

Final Thoughts:

CW cable glands remain an essential component in armoured cable installations where strength, safety, and reliability are required. With proper sizing and installation, Brass CW Cable Glands provide long-term performance for indoor electrical systems.
