Technical Standards & Architecture
What Is Included in a XinHuan Transformer Submittal Package?
Every project submittal drawing generated by XinHuan complies with international drafting standards (ISO 5456 / ANSI Y14.5) to ensure seamless review and fast sign-off by utility engineers and consulting firms.
1. Dimensional Views & Clearances
- Front elevation, side elevation, and top plan views
- High-voltage (HV) & low-voltage (LV) terminal bushing center-to-center phase clearances
- Overall physical envelope dimensions ($L \times W \times H$ mm)
- Safe electrical clearance radius to surrounding civil walls
2. Civil Foundation & Mounting Footprint
- Base channel mounting gauge (e.g. 550mm, 660mm, 820mm, 1070mm track pitch)
- Foundation anchor bolt hole coordinates and diameters
- Bi-directional roller wheel orientation (longitudinal / transverse)
- Jack lifting pads and top crane lifting lug load ratings
3. Electrical & Mechanical Schedule
- Vector group connection diagram (Dyn11, YNd11, Yyn0)
- Off-circuit / On-load tap changer switching table with % voltage steps
- Weight schedule: Core & coil weight, oil volume weight, total shipping weight
- Bilingual rating plate legend and terminal marking nomenclature

Technical Questions
Frequently Asked Questions — Transformer CAD Drawings
Yes. For retrofit and substation replacement projects, we frequently customize high-voltage and low-voltage bushing heights, phase center-to-center spacing, cable box orientations (top, bottom, or side entry), and terminal flag drilling patterns to achieve 100% drop-in alignment with existing civil busbars and cable trenches.
Yes. In addition to 2D AutoCAD (.DWG / .DXF) files, we export 3D solid STEP (.stp) and IGES (.igs) files that can be directly imported into Autodesk Revit, Navisworks, SolidWorks, and Bentley Substation software for 3D clash detection and spatial clearance verification.
Simply submit your project single-line diagram (SLD) and tender technical requirements via our online RFQ portal or email [email protected]. Our engineering department will assign a dedicated design engineer and supply the full submittal package (GA drawing, electrical schematic, loss guarantee sheet, and type test certificates) within 24 hours.
