Glands

Cable glands are essential mechanical fittings that secure and seal electrical cables where they enter enclosures, switchboards, junction boxes, and electrical equipment. For licensed electricians working on residential, commercial, and industrial installations across Australia, quality cable glands ensure compliant, safe, and long-lasting cable terminations that meet AS/NZS 3000:2018 standards.​

These critical components serve multiple functions in professional electrical work: they provide strain relief to prevent cable damage from pulling or twisting, create watertight seals to protect against dust and moisture ingress (IP-rated protection), and maintain the integrity of electrical enclosures. Many cable glands also provide earthing continuity for armoured cables, ensuring proper grounding throughout the installation.​

iSupply Electrical stocks an extensive range of cable glands from trusted brands including ABB, Cembre, Cabac, Kopex, and Nicote, with sizes ranging from M12 to M75 to accommodate cables from small data installations to heavy industrial power applications. Whether you’re working with unarmoured cables requiring standard nylon glands, armoured cables needing brass or steel terminations, or specialized applications requiring explosion-proof (Ex) rated glands for hazardous locations, you’ll find the right solution in our Electrical Accessories category.​

Available in both metric and PG thread standards, our cable gland selection includes single and double compression types, quick-connect designs for faster installation, and EMC-rated options for applications requiring electromagnetic interference protection. All products meet Australian compliance requirements and offer the durability and reliability electrical contractors need to complete projects on schedule without callbacks or failures.​

Frequently Asked Questions

What is the purpose of a cable gland in electrical installations?

Cable glands secure and seal the point where electrical cables enter equipment or enclosures, providing critical strain relief to prevent cable damage, creating moisture and dust-tight seals to maintain IP ratings, and offering earthing continuity for armoured cables. They’re mandatory components for compliant electrical installations under AS/NZS 3000:2018 standards.​

What’s the difference between nylon and brass cable glands?

Nylon cable glands are lightweight, corrosion-resistant, and cost-effective for standard indoor applications and unarmoured cables, while brass cable glands offer superior mechanical strength, earthing capabilities for armoured cables, and better performance in harsh environmental conditions or industrial settings. Brass glands are typically required for SWA (steel wire armoured) cable terminations.​

How do I select the correct cable gland size?

Cable gland sizes (M12, M16, M20, M25, M32, M40, M50, M63, M75) indicate the thread diameter in millimeters. Match the gland’s cable diameter range to your cable’s outer diameter measurement—for example, an M20 gland typically accommodates cables with outer diameters from 10-14mm. Always verify the manufacturer’s specifications for the exact cable size range.​

Are cable glands required to meet Australian electrical standards?

Yes, cable glands used in Australian electrical installations must comply with AS/NZS 3000:2018 (Australian/New Zealand Wiring Rules) and relevant IEC standards including IEC 62444 for cable glands in electrical installations. All glands supplied by iSupply Electrical meet these compliance requirements for use by licensed electricians.​

Can cable glands be used in outdoor or hazardous locations?

Cable glands are available with various IP (Ingress Protection) ratings for outdoor use, providing sealed protection against dust and water ingress. For hazardous locations with flammable gases or explosive atmospheres, specialized explosion-proof (Ex) rated cable glands with Ex e or Ex d certifications are required and available in our range.​

What are EMC cable glands and when are they needed?

EMC (Electromagnetic Compatibility) cable glands provide electromagnetic shielding to prevent interference in sensitive electronic equipment and control systems. They’re essential for industrial automation, instrumentation, and telecommunications installations where electromagnetic interference (EMI) or radiofrequency interference (RFI) could affect system performance.
