Nitrogen is placed in transmission lines to:

Keeping transmission lines dry and clean is essential for maintaining insulation and preventing arcing at high RF power. Dry nitrogen is inert and has very low moisture content, so it’s used to purge and fill lines to displace humid air. By pushing moisture out, the dielectric strength of the line is preserved and the risk of arcing or corona is reduced. This practice doesn’t directly affect skin effect, or the standing-wave ratio, which are determined by the line’s geometry and impedance. The primary purpose is to prevent moisture from entering the line.
