Electricity travels across long distances or through rough environments; it needs more than just a regular wire to handle – the armor. When some sit behind walls, armoured cables withstand the harshest conditions. But what is an armored cable, and how does it differ from regular cables?
Engineered for strength and safety, it powers outdoor systems, runs through construction zones, and operates in industrial settings. Bury underground or lay through conduit, and see how your power stays protected and uninterrupted.
Continue reading and you’ll see what makes armored cable unique, where it’s used, and why it might be the right choice for your next project.
What is an Armored Cable?
Armored cable, also known as a strip wire armored cable, is a type of electrical cable made specially to withstand harsh environments. What makes it different from regular cables? Not like the regular ones that have a conductor and insulation, armor cables go a step further, adding an extra protective layer that’s tough and metallic, to wrap around and guard it from external damage – Physical damage, rough weather, chemical corrosion, and more.
Constructed with copper or aluminum conductors, XLPE insulation, PVC sheath, and steel armor layer, it serves as a strong barrier to protect the inner core of the cable and make sure that the electricity flows smoothly. This is why they are commonly available in outdoors or in demanding conditions.
Where and When to Use Armored Zabe Cable?
Armored cables handle tough environments, making them the right choice for areas with high risk of physical damage and external stress. Featuring a protective metal layer to guard the inner conductors from possible threats, it eliminates the need for additional conduit in many cases (check before proceeding).
Have you wondered how electricity travels inside exterior walls, stairwells, underground runs, barns, basements, and more similar places that demand durability? It’s what armored cables do. Different types of armored cables serve different purposes. For example,
- PVC armored cables for moisture-prone environments
- Fire alarm cables for alarm systems to keep on working during harsh cases
- Marine-grade variants to work for maritime conditions.
- XLPE-armoured cables for high-voltage setups (handle up to 1000V in configurations like 6mm 3-core)
As you now know, the answer to “what is an armored cable?”, you need to recognize the right type for your cabling needs.
What are the Types of Armored Cable?
Steel Wire Armored Cable
This is a common type of armored cable made of steel and is mostly used in multi-core cables. As this cable is of built strength, it is used in applications like underground systems, outdoor lighting installations, and power networks.
Aluminum Wire Armored Cable
This uses aluminium armour instead of steel and is lighter in weight. Applications where lower weight is beneficial use this cable to transmit power over long distances. It is non-magnetic, used in single-core cables, and is used instead of steel wire-armed cable to prevent overheating in AC systems.
Aerial Bundle Cable
This type of armored cable has multiple conductors with armouring and insulation. They are mainly used in secondary overhead lines on poles or as feeders to residential premises.
Steel Tape Armored Cable
This cable is with steel tape armouring and has a thin protective layer. It is used in applications where cables are installed indoors or buried in limited spaces that need protection.
How to Install Armored Cables?
Armored cable installation needs to be precise! This is especially important when working with high voltage applications. Follow the guidelines or the manufacturer’s instructions to install the cable, and here is a general guide to do it.
- Identification of the Right Cable
Choosing the right cable is the main step for safe and efficient electrical setup. Therefore, identify the right voltage rating for your application.
- Preparation of the Junction Box
Get the junction box ready before laying the cable. It should be clean, accessible, and secured properly.
- Measuring Cable Length
Measure the distance between connection points to find out the length of armored cable. Make sure you don’t waste it.
- Cable size cutting
Cut the armoured cable to the correct length after measuring. You can use the appropriate cutting tools for clean and even cuts.
- Installation of the Anti-Short-Circuit Liner
Fit an anti-short-circuit cylindrical lining at the point where the cable enters the junction box. This is to protect the cable from any short circuits caused by contact with metal edges.
- Connector Attachment
The appropriate connector should be securely attached to the end of the cable for a strong connection to your junction box.
- Wiring Completion
Connect the cable to the junction box. Double-check that all terminals are properly tightened. Look for the bend radius of the cable to not exceed at any point during the installation.
What are the Benefits of Armored Cable?
Protection: Armored cables do not get easily damaged and so can be installed in harsh environments.
Safety: The extra layer of insulation prevents electrical faults and short circuits, reducing the risk of electrical shock and fire hazards.
Versatility: Applies to various applications, and can be used underground, overhead, and outdoors.
Durability: Withstands harsh conditions for a long period of time, and so is in areas with high foot traffic.
Cost-Effective: More expensive than regular cables but with less maintenance and longer lifespan, they are a cost-effective solution.
