Some neat things going on there regarding the cable. If I see it correctly, it looks like a few fibers snap at 0:02. Then nothing happens until 0:05. Stepping frame by frame with comma and period, it seems like a few more fibers snap, after which the strain is too much and the cable just explodes.

Cable number 2 goes in a more gradual way.

And on cable 3 there is a prominent wave before it falls to the ground.
