What is a single core cable?
A single core cable means it has one wire going through the outer casing.Like a 3 pin plug has 2 or 3 which are (blue)-Neutral,(Brown)-Live and maybe (Green/Yellow)-Earth which would be 2 or 3 core.
Can aluminum be used as a gland plate?
yes,for non Ferrous application and in the places where a single core cable is used. Else it not required to use a Aluminium gland plate
Why aluminium armour is required for single core cable?
To prevent for circulating the magentising current.
What is the difference between single core and multi core wires?
Single core has one single piece of metal wire, maybe copper or aluminium, with insulation around it. It is not very good if you want the cable to flex and bend as it is more likely to just bend and stay there in the new position. Multiple-strand cable has lots of thin wires and this makes it more flexible and likely to spring back
Where core cable and pair cable is used?
Assuming you're taking about 'twin core and earth' cable - it's commonly used to supply power to high-current devices such as cookers and immersion heaters.
What is the difference between 2 core and 3 core wire?
A two core cable is used where an earth is not required. A three core cable is used where an earth is requred. Specialised three core cables are available for 3 phase and two-way switching applications.
How many dewa cable from transformer to mdb?
11 CABLES 630 mm2 single core
Does a 4corex630 sq mm cable carry the same current as a single core 630 sq mm cable?
4-core 630 mm-sq cable sounds like 4 cores each of 630 mm-sq as used on 400 kV power lines, in which case it carries 4 times the current.
When you clamp a single core cable carrying about 500A with an aluminum cable clamp do you have to take care of any effects due to Eddy currents and If so what can you do to minimise these effects.?
Assuming the single core cable forms part of a three phase circuit (i.e. you are clamping three single core cables) it is best to install the three cables close togther in what is called "trefoil" formation. This harmonises the Eddy currents of each phase.
Why single-core cable armoured with steel wire or tape must not be used for a c circuit?
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
Which types of fiber optic cable would have a core size of 8nm and a cladding size of 125nm?
Single-mode Fiber
Do you class a twin and earth cable as a two core or a three core cable?
2
