Is there something special about these? What are the benefits?
I have 2-3 cables with integrated fuse

aha...Thank you Sir.
I was planning to visit their showroom over the weekend anyways...you have just confirmed it.

The first post illustrates a UK-type flat-pin (they call them "square-pin, don't know why, perhaps just because they are not round!) plug. These are used in UK and Singapore.

Just some basic protection against higher current than they are designed for. The thin wire in the fuse will heat up and burn/melt thereby breaking off the circuit and stopping the flow of current to the equipment.
What do you mean you have cables with in-built fuses? can you send a picture or link to one?
Very good plug. Available in MX showroom at Laxmi Industrial Estate, Andheri West. Not even costly.

According to what I have been told, the fuse in a plug is not to protect the equipment or the user: fuses protect upstream. The fuse in the plug will blow before the circuit breaker blows, the circuit breaker will blow before the main breaker blows, and the main breaker will blow before your local transformer explodes.
Oh wait, include the cable in that too: it all helps to prevent the upstream cables from burning out.

Then, what about the equipment downstream ... No protection ? Do those spike busters help , the ones that are available with 6 power sockets and claim to be protective ?

Right. No protection --- which is why those spikes are our enemy and mortal dread!
I don't understand....how will the cables and circuits upstream burn out? My equipment is not sending any power upstream.
I've heard of too much water coming down from the dam and submerging what comes in the way.....water going up to damage the dam is unheard of.

If it shorts out, or the voltage drops so far the current increases enormously, then your equipment will draw that much power.
On top of this, the people who understand Alternating Current might have something to add about the upstream/downstream analogy. My understanding doesn't go that far.
If the wires short, the circuit would just trip at the mains. If the voltage drops, the current would actually decrease, not increase.
Here's an article that explains fuses and surge protector. How do surge protectors and fuses work? - Explain that Stuff
Basic and simple, but good explanation.

This may depend on what kind of equipment it is, but... If an electrical device is doing a certain amount of work, at a given voltage it will draw a given current; at half the voltage it will drawn twice the current, because it needs the same amount of energy to do the same amount of work.
