I am sure you must have verified but worth to check again.
If one winding only and two neutral connected -one with NGR and one without, what purpose does NGR servces?
Am I missing something?

Ask the mfr. as to what they are.

For your response when i contact manufacturer he has given reply ie two neutrals provided one is exposed to environment and another one is in the cable box.we have been using cable from neutral to NGR.Depending upon type of termination kits using we have to choose the neutral.If we are using Outdoor termination kit we have to take neutral from the Bushing ann indoor termination kit we have to take it from the box.

Keep the one that connected to NGR. Disconnect the one that is directly bonded to the ground, according to your original post, because that one will simply bypass (short out) the NGR!
