Underground cables are 'armoured' in order to protect them against mechanical damage. This armour takes either of two forms: (1) steel tape, or (2) wire. Wire armour tends to be used on cables with a larger diameter, as it makes them more flexible compared to cables with tape armour.

In both cases, the armour is spiral-wound towards the outer part of the cable along its length and is, itself, protected with a hessian or plastic outer layer.

How do you choose armoured cable?

The use of armoured cable is determined by the application that needs an electrical source of voltage. It is a metal sheath cable classification. Armoured cable is used in applications that need mechanical protection usually below a certain elevation. Armoured cable is also usually used on surface wiring. If you have access to an electrical code book there is a whole section on armoured cable. In the CEC the section about armoured cable starts at 12-600 to 12-618.


What is the difference between armoured cable and un-armoured cable?

The difference between and armoured and un-armoured cable is in their outer layers. Armoured cable has additional outer protective layer of steel or aluminium while un-armoured has a PVC or nylon outer sheath.


What is the difference between armoured unarmoured and flexible cables?

Armored Cable: Armored electrical cable contains insulated electrical service wires protected by a flexible steel covering. Unarmored Cable: Unarmored electrical cable has no protective flexible steel covering, its covering is made of plastic.

What are the advantage of using copper wire armoured cable?

The advantage of using armoured cable over rigid conduit systems is the flexibility of the cable.

what are cable glands?

Cable Glands cover the whole spectrum of armoured and non-armoured cable and applications from general industrial through increased safety, deluge, flameproof and explosion proof. The Cable Glands are available in Brass as standard with Stainless Steel, Plastic and Aluminium, as an optional material on certain designs. Generally they are used by oil and gas units, electrical cable sealing companies and marine applications. Depending on the applications they are many type of cable gland available like indoor cable glands, outdoor cable glands and cable gland accessories like PVC shrouds, lock nuts and cable ties.

What is an armored wire?

A cable with a steel sheath.AnswerArmoured cables are cables designed to by laid underground. An armoured cable is a cable whose conductors are protected from mechanical damage by an outer layer of steel tapes or wire. The armour itself is protected against corrosion by an outer waterproof layer. The steel tape or wire is wound around the cable to maintain its flexibility.
