We don't know that the "maximum operating temperature" of a transmission line can ever be changed or influenced. Say the "maximum operating temperature" is 100. Two things that affect the temperature of the transmission line are: amount of electrical load, and wind speed/direction. When there's too much electrical load on the line, the temperature will exceed 100 degrees. When there's an average electrical load on the line, maybe the resting temperature is 85 degrees. While operating at this "average load", the temperature of 85 degrees can still be affected by strong & perpendicular winds. If it's a particularly windy day, maybe the line temperature is 75 degrees as opposed to a completely still & neutral day.
C) Says that the electrical load the line can carry WITHOUT reaching maximum increases when wind speed increases. Maybe the average electrical load is actually 50% of maximum capacity (because if we turn it up to 100% then the line temperature will pass 100 degrees temperature). Since wind speed decreases the "resting temperature" from 85 degrees to 75 degrees, we can lightly assume that the average load can be turned up - from 50% to at least 51%.
E) This says that the MAXIMUM OPERATING TEMPERATURE - the one we established to be 100 degrees - is changed by windy degrees. This is unsupported. Maximum operating temperature is just that - the maximum. It's like the limit that comes with the design of the product. You can't change the maximum temperature you can set your oven to, but you can change the temperature of your oven WITHIN that range.
