At the MV-LV boundary, cable trenches, fire walls, and protection panels depend on the same installation date as the transformer set-down.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">For substation transformer delivery, the purchase order should reference measurable logistics parameters\u2014shipping weight, overall dimensions, center of gravity, oil status (filled or dry), lifting points, and required escorts\u2014rather than a calendar promise alone.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Cross-check public product scope on <a href=\"https:\/\/shenhengglobal.com\/es\/\">Shenheng Power<\/a> and confirm final transport and civil limits with your utility or consulting engineer.
