The manufacturer source is linked for revision checks; preview images are for inspection and the original drawing supplies the design dimensions. The source table supplies the listed product values. The project insulation, mechanical loading and regional requirements must be checked for the selected installation. Use the 1050 HU column on PDF page 11. The download is the complete catalogue, not a standalone DWG or STEP part. ## In plain English ### What the equipment does A station-post insulator supports an energised conductor while separating it electrically from its grounded support. Its end fittings, height and mechanical strength determine how it can be mounted. ### A simple example When positioning 1050 HU on a substation support, use PDF page 11 to compare its mounting interfaces with the structure and conductor connection. The listed Height (in) is 92. ### What the drawings help you do Download PPC_ANSI_Solid-Core_US-Letter-updated-LQ.pdf and open PDF page 11. Find the 1050 HU column; other tables and model rows or columns describe different insulators. This source is a catalogue PDF. A native DWG or STEP file is not included; use Request CAD for an editable model. ### Before using this reference - For 1050 HU, the source records Height (in): 92. Match that value to the conductor-support arrangement. - Compare the 1050 HU column on PDF page 11 with the exact fixing or stud arrangement shown in the catalogue; use the dimensions for this exact reference. - The source also lists Top BCD (in): 5. Check the project requirement against the manufacturer’s specified units and conditions. - BCD or PCD is the diameter of the circle through the fixing-hole centres. Compare both top and bottom fixing patterns with the supporting structure and conductor fitting. - Leakage distance follows the insulating surface. It is different from the overall height; use the height value for the physical layout. ### Where is the 1050 HU information in this download? Open PDF page 11 of PPC_ANSI_Solid-Core_US-Letter-updated-LQ.pdf and find the 1050 HU column. The page preview preserves the manufacturer table; the download contains the complete catalogue. ### Is an editable CAD model included for 1050 HU? This entry provides the manufacturer PDF reference and its model-specific values. A DWG, DXF or STEP model is not attached; request the exact model and preferred format here. ### Terms - CAD: Computer-aided design files used to prepare drawings and models. - Revision: The recorded version of a drawing or model. Concept diagram: Identify the support position → Match the named reference and fixing → Coordinate the structure and conductor A simplified explanation of how this item works. It does not show terminal wiring or an operating procedure. - [PPC Insulators official source](https://ppcinsulators.com/wp-content/uploads/2017/06/PPC_ANSI_Solid-Core_US-Letter-updated-LQ.pdf#page=11) ## Which file should I choose?
