National Armoured Cable

120MM refers to the overall size/diameter of the cable, including its armour, while 4C indicates four copper conductors inside the sheath. This configuration supports multiple conductors for live, neutral, and earth connections in a single run.

The armour provides mechanical protection against impacts, abrasion, and environmental exposure. It helps prevent damage from external forces and improves reliability in challenging environments.

It's suitable for a variety of applications, including indoor and outdoor installations, exposed outdoor areas, underground routes where permitted, and environments where protection against physical damage is important.

Plan the route with appropriate bends and avoid sharp kinks. Use suitable conduit or glands at terminations, secure the cable with appropriate clamps, leave slack where needed for movement, and follow standard electrical installation practices for cutting, stripping, and terminating 4C copper conductors. Use correct tools and avoid damaging the armour during installation.

The cable is designed to resist fire and corrosion, and to minimize electrical interference in sensitive applications. Its rugged armour and copper conductors meet general safety and durability expectations for industrial and outdoor use, aligning with common electrical protection standards.

If you’re considering alternatives on Fepy, you can also review: Armoured Cable 4C 100mm (https://fepy.com/product/armoured-cable-4c-100mm) and Armoured Cable 4C 150mm (https://fepy.com/product/armoured-cable-4c-150mm). These offer similar four-conductor copper construction with armour but in different outer sizes to fit your project requirements.

Determine the required current load and distance, then select a cable with adequate conductor cross-section (4C copper) and a length that minimizes joints while allowing for bends and slack for termination. The 120MM size suits many general-purpose installations, and Fepy typically offers various lengths to match your layout.

Periodically inspect the armour for visible damage, ensure terminations are intact and sealed, and replace any damaged sections promptly. Keep the cable route clear of sharp edges and avoid repeated flexing or bending beyond recommended limits.

Yes, the design emphasizes fire resistance and durability in challenging conditions, making it appropriate for environments where fire safety and reliability are important.

National Armoured Cable combines a robust armoured jacket with four copper conductors for reliable power transmission, plus a reputation for quality. Its 120MM size and available length options provide flexibility for many installations, and you can compare against other 4C armoured cables on Fepy (for example, 100mm and 150mm variants) to choose the best fit for your project: 100mm option: https://fepy.com/product/armoured-cable-4c-100mm; 150mm option: https://fepy.com/product/armoured-cable-4c-150mm.
