Seems to me a trefoil cable arrangement is related to bundling the hot, return (ground) and neutral wires in a triangular formation so to minimize the path resistance (response time) in case of fault conditions (a short).

What is the advantage of trefoil formation of HV power cable?
trefoil arrangements of same phase mimimise stray loss
Recommended span between trefoil clamp?
usually 1m generally depending on cable size
Why trefoil formation for single core cable?
Voltages are induced in the sheath of cables running in parallel which result in circulating currents flowing in the sheaths. The distances between single core cables running in parallel determine the voltages induced. With single core cables in trefoil formation (touching each other) the distances between the cables are minimum and thus the voltages induced are minimised and hence the circulating currents.The circulating currents cause localised heating.
What is an example with trefoil and the present simple tense?
As trefoil is a noun , you must choose a verb to use with it. For instance, 'I have a trefoil plant at home.'

Can you trefoil same phase cables?
can do trefoil to the same phase cables
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.
