Thanks for your quotation.
We ask for 2 sets of DS with grounding and 10 sets of DS without grounding. I believe your proposed item 1 and 2 should have been 10 sets and 2 sets, respectively. Please confirm.
The distance between phase of the existing DS is 2400 mm. So, our proposed DS must have the same interphase distance. Please confirm the proposed DS meet this requirement.
Best regards,
