Types of Armoured Cables and How to Select the Right One

Armoured cables are among the top choices when it comes to providing safe, durable, and reliable power transmission for residential, commercial, and industrial applications. Their durable construction protects against mechanical damage caused by harsh environments or underground installations as well as mechanical wear-and-tear. As one of the leading cable manufacturers in India, Dynamic Cables Limited offers a wide range of high-quality electrical wires and cables designed for long-term performance.
In this guide, we explain the different types of Armoured Cables, where they are used, and how to choose the right one for your specific requirement.

What Are Armoured Cables?

Armoured Cables are power or control cables reinforced with steel or aluminium armouring. This additional layer provides superior mechanical protection for the cable, making it suitable for underground, outdoor and industrial installations \- including industries, utilities, EPC contractors and large infrastructure projects. Industries often turn to them.
As a trusted wire and cable manufacturer, Dynamic Cables Limited ensures that every cable is built with precision, to strict quality standards, and with superior materials.

Different Types of Armoured Cables

1. Steel Wire Armoured (SWA) Cables

These are among the most common types of Armoured Cables used for electrical power transmission. The steel wire layer offers high tensile strength, making SWA cables ideal for underground installations and industrial zones. They are suitable for medium mechanical stress conditions.

2. Steel Tape Armoured (STA) Cables

STA cables feature an armor layer made of steel tape for superior resistance against crushing forces, making them an excellent solution for fixed installations such as ducts or trenches. STA is perfect for power distribution networks as well as heavy-duty industrial applications.

3. Aluminium Wire Armoured (AWA) Cables

AWA cables are typically used for single-core power cables to reduce losses caused by steel armouring. Aluminium armouring provides excellent mechanical protection at reduced weight and cost, and AWA cables are often preferred by electrical cable wire manufacturers for large-scale installations.

4. Armoured Control Cables

Control circuit and machinery operations use these cables, designed specifically to protect against mechanical damage and interference, making them perfect for automation systems, power plants and industrial machinery.

5. PVC and XLPE Armoured Cables

Both PVC and XLPE insulation options are available in Armoured Cables.

• PVC Armoured Cables: Suitable for standard applications, budget-friendly, and easy to install.
• XLPE Armoured Cables: Offer higher temperature resistance, improved current-carrying capacity, and durability.

Dynamic Cables Limited, a leading electrical cable manufacturer in India, offers a range of variants suitable for diverse industrial needs.

How to Select the Right Armoured Cable?

Choosing the right Armoured Cables depends on the following key factors:

✔ 1. Application & Installation Environment

Is the cable intended to be installed underground, connected to industrial machinery, or externally wired? To meet heavy-duty conditions STA or SWA cables are often preferred.

✔ 2. Voltage Rating

Different projects require different voltage levels. Check whether you need LV, MV, or HV cables.

✔ 3. Conductor Material

Copper conductors offer high conductivity, while aluminium options are more cost-effective.

✔ 4. Insulation Type

PVC or XLPE insulation is selected based on temperature, load, and application requirements.

✔ 5. Certification & Quality Standards

To select cables manufactured from reliable wire and cable suppliers that adhere to ISO standards, conduct quality checks regularly, and offer full technical support services, it is wise to invest in cables produced from companies who comply with them and which meet these criteria.
