Hello, I think that power tower is where aereal power line passes to underground cable to nearby wind power generators (Termination mean cable terminals). I am not shure about line voltage. effectively the voltage is high it can't be 132kV. for that type of generation is used usually medium voltage (probably 20kV) only way to know is going on site and see with the eyes of an electrician (counting insulators in a chain of insulators is one of the methods)
