What Are Armored Cables?

Armored cables are electrical cables encased in a protective metal sheath, usually made of steel or aluminum. This sheath shields the cables from physical damage, making them ideal for demanding environments.

You can explore our Armored Wires & Cables section for high-quality options designed to handle these challenging conditions.

When to Use Armored Cables

1. Industrial or Commercial Environments

Armored cables are designed to withstand harsh conditions, such as:

• High temperatures
• Heavy machinery vibrations
• Exposure to chemicals

Example: Factories, warehouses, and manufacturing plants often require armored cables to protect critical electrical systems.

2. Underground or Outdoor Installations

When cables are buried underground or exposed to the elements, the metal sheath of armored cables prevents physical damage from moisture, rodents, or accidental digging.

For underground and outdoor needs, check out our selection of Armored Wires & Cables designed to meet these challenges.

3. High-Traffic Areas

In places where cables are subject to frequent contact, such as offices, schools, or hospitals, armored cables provide extra durability and safety.

Why It Matters: Non-armored cables are more prone to wear and tear in high-traffic environments.

When to Use Non-Armored Cables

1. Residential Projects

Non-armored cables are lightweight, flexible, and easier to install, making them ideal for indoor residential applications like lighting, outlets, and appliances.

Note: Ensure the cables are routed through walls or conduits for added protection. Visit our Wire, Cord & Cable section to explore more options.

2. Budget-Conscious Projects

Non-armored cables are more affordable than their armored counterparts, making them a cost-effective solution for projects with lower environmental risks.

Example: Simple indoor wiring for small office spaces or retail stores.

3. Environments with Conduit Protection

If the cables are already routed through metal or PVC conduits, non-armored cables are a suitable option as the conduit itself provides adequate protection.

Benefits of Armored Cables

• Durability: The metal sheath protects against physical damage and environmental factors.
• Safety: Reduces the risk of electrical shocks or short circuits caused by damaged insulation.
• Compliance: Often required by building codes in industrial and commercial settings.
• Longevity: Designed for longer lifespans in challenging environments.

FAQs About Armored and Non-Armored Cables

Q1: Are armored cables more expensive than non-armored cables?

Yes, armored cables typically cost more due to their protective metal sheath. However, they save costs in the long run by reducing maintenance and replacement needs.

Q2: Can I use armored cables for residential wiring?

While they’re not typically used in residential settings, armored cables can be installed in areas requiring extra protection, such as basements or garages.

Q3: Are armored cables waterproof?

Not all armored cables are waterproof. Look for cables with specific water-resistant ratings for outdoor or underground installations.

Conclusion

Choosing between armored and non-armored cables depends on the project’s specific needs. For high-risk, industrial, or outdoor environments, armored cables are the go-to option for their durability and safety. For simpler, indoor projects, non-armored cables are a cost-effective and practical choice.
