Why single-core cable armoured with steel wire or tape must not be used for a c circuit?

∙ 10y ago
Current in the single core cable would induce a magnetic current in the steel cable, though a transformer effect.
This would heat the steel armored strands, and the circuit would increase more electrical power from the load supply point.
The earthing of the cable glands would complete the circuit and the return current would flow in the earth bonding cable between the two points.
This is called Eddy currents generated in the cable by the twist of the steel armored around the central core, current flowing in one direction

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.
What are the advantages and disadvantages of using steel wire armoured cable?
The advantage is that it is strong and can stand up to many types of weather. Disadvantage is that it will get rusty easy.
What is sta cable?
Steel tape armoured(STA) is only used for buried cables or ordinary wear tube, common ground, tunnel laying. For the last of the cable package to protect. Steel tape armoured is one kind of armored cable. General use the left double gap around the package, the lapping gap is not greater 50% of the bandwidth. And the inner steel strip gap should be close to the middle part of the outer strip. Steel tape armoured commonly used galvanized steel and painted steel armor, common specifications can be divided according to the thickness: 0.25mm,0.3mm,0.5mm,0.8mm. Galvanized layer should be uniform and complete, no peeling, cracking, corrosion. The coating layer of painted steel strip should be uniform and continuous, allow a slight sagging, bruises, but may not have a large loss or missed.
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.
What is the difference in armoured and unarmoured cables?
Cables are two or more wires running side by side and bonded and there is armored and unarmored cable. Armored cables are protected by flexible steel covering while the unarmored cable is only covered by plastic.
What are armoured truck tire made of?
synthetic rubber and steel.

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.
What is the definition of a steel wired armoured cable in electrical engineering?
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.
