Power and signal transmission cannot compromise on protection. The insulating layer protects against electrical and thermal damage, but in many applications, it doesn’t have enough mechanical strength. Cables in industrial machinery and underground installations are often subjected to mechanical load. Without proper shielding, they cannot last long in such environments.
Armoured cable has evolved as a preferred choice to protect against the impact or crushing forces. Let’s understand its design, purpose, and how it has transformed the way electricity or signals are transmitted.

Understanding the Armoured Cable Design
Harsh conditions in industrial environments or underground installations often damage the cables due to mechanical forces. The typical insulation fails under pressure and impact. Armoured cable was invented to overcome this limitation. In its design, a metal sheath is added between the conducting wires and the outer insulation. This is called the armour layer, which adds strength to the cable. Steel wire armour is a common type used in vast applications.
How To Choose An Armoured Cable?
To identify the best armoured cable for your specific project, here are some factors to consider:
Current Capacity and Size
Calculate the total load and match it with the current capacity and the thickness of the cable.
Cable Length
Voltage drop leads to energy loss. Thick cables reduce the energy loss caused during long cable runs.
Number of Cores and Conductor Type
Note the number of cores you need based on your installation. Copper and aluminium are the two conductors that you need to pick.
Safety Features
Decide whether you need FRLS grade or zero halogen minimum smoke armoured cable.
Benefits of Armoured Cables in Transmission
Here are the top benefits of armoured cables in current and signal supply:
- Protects the cable from accidental digging, rodents, and pressure from soil underground.
- Ensures an uninterrupted power supply or signal transmission by absorbing stress.
- Long cable runs can be installed within an infrastructure without needing a conduit.
- Reduces the need for cable repairs and replacement because it prolongs the lifespan of the cable.

FAQ's
This question is frequently searched by consumers and professionals looking to compare brands before buying wires or selecting a supplier for construction or industrial projects. The most mentioned companies in top-10 industry lists include Rajdhani Cables, Polycab Wires Pvt. Ltd., V-Guard Industries, KEI Industries, Finolex Cables, Sterlite Technologies Ltd, Syska Wires, Plaza Wires, Goldmedal Electricals, RR Kabel Ltd.
Users often search this when they want to know what factors to consider — such as conductor material, insulation type (PVC, XLPE), safety standards (BIS/ISI/IEC), and resistance properties — before buying cables.
This question ranks high because many buyers want to know what BIS, ISO, IEC, RoHS etc. stand for and how they ensure safety, durability, and compliance when selecting cables.
People often search for cable classifications such as power cable, control cable, LV/MV/HV cable, fire-resistant cable, telecom cable, etc., to understand which type is suitable for their needs.
This is a popular beginner question — especially among homeowners or DIY installers — because many don’t know how wires and cables differ in structure, conductors, uses, and electrical properties.
