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 cut an 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 unarmoured and flexible cables?
Armored electrical cable contains insulated electrical service wires protected by a flexible steel covering. Unarmored electrical cable has no protective flexible steel covering, its covering is made of plastic.
Define 2XFY in electric cable?

Why is it likely that a separate earth conductor cable is run with armoured cable?
Running a separate earth conductor cable with armoured cable is likely due to safety and regulatory compliance. The separate earth conductor ensures effective grounding, reducing the risk of electric shock and improving overall system safety. Additionally, it provides a dedicated path for fault currents, enhancing protection against electrical faults. Furthermore, using a separate conductor can help maintain the integrity and performance of the main power conductors within the armoured cable.
What is the maximum voltage rating for AC-90 armoured cable?
The maximum voltage rating for AC-90 armored cable is typically 600 volts. This type of cable is designed for use in various applications, including building wiring and power distribution, and is suitable for both indoor and outdoor installations. It's important to ensure that the cable is used in accordance with local electrical codes and standards.

What is the meaning of YRY cable?
Yry means copper round armoured cable
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. There are some situations where conduit can not be bent into the shade needed to make a proper connection to a device. Because of the flexibility if the armoured cable it can be used instead to make a presentable looking job.
What is live in electrical engineering?
"Live" means that there is current running through the cable or wire or system in general.
What is SWB armoured cable?

What is the function of 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.
Can I see a photograph of armoured cable?
yes, but picture can not be enclosed here
What is the meaning of the 2xfy in cable?
Copper XLPE Armoured Power Cables.
What is bend radius of power cable how can you calculate the bend radius of 3c xlpe 240sqmm armoured cable having diameter of 100mm?
The radius of the curve of the inner edge of the bends shall be at least 6 times the external diameter for armoured cable.
