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.
Can 3 phase power and single phase be ran in the same conduit?
Yes they can. There are regulations that cover most jurisdictions regarding how different cables can be contained. It is important that you are knowledgeable about your local requirements before starting the work.
How you convert the value of single phase power to value of 3 phase power?
Electric power is measured in watts. It does not matter if it is single phase or three phase. All things being equal, for the same load, the power measured in a single phase circuit or a three phase circuit, will be the same.
Is it possible to extend the service of a 3 phase generator rated at eleven KVA and 8000 Amperes 150 to 200 meters down line with power cables?
Yes, it is possible to extend the service of a 3-phase generator with power cables. However, the length and gauge of the cables need to be considered to ensure there is no significant voltage drop over the distance. It is recommended to consult with an electrician or engineer to determine the appropriate cable size for the desired length.
Why you use only single phase and three phase supply?
Single phase requires 2 wires - a hot, and a return (both wires of the same size. Three phase requires three (same size), and if it is grounded will require a forth (doesn't normally carry current so it can be small). Two phase requires three wires (two phase conductors of one size, and a return that can handle double the current of the phase conductors), or four wires (same size for all, effectively two separate single phase supplies). It isn't economical is the bottom line. It costs ~the same (in wire) for two phase as three, and you get 50% more power delivering capability with three phase.

Are dog run cables the same as dog tie out cables?
No, dog run cables and dog tie out cables are not the same. Dog run cables are typically longer and allow more freedom of movement for the dog, while tie out cables are shorter and restrict the dog's movement to a specific area.
