Cat8 is then what you want. Each tp is shielded individually. They are thick and hard, however, and bulky. If your setup is stationary cat8 is an excellent choise.
Let me check the mosfets.
It may. Depending on the distance.
This is a recent thread.
Discrete mosfets have never been in shortage. Challenge is to design the board, as they require drivers and an MCU to drive them. Any mosfet would work. If you need high voltage, high current mosfet, there is one I really like, it’s available for SMT, you don’t have to burn your fingers soldering it:
JLC part number C108964, 300A / 100V
If you are not constrained for space, this is the sledge-hammer that could drive a 12-inch nail spike into a railroad tie. Six of those could power a golf cart.
