Download the verified original here. 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 C10-1050 2300 ± 3.5 280 127/4x M16 225/4x18 275/8x18 10 4.6 23 4 column on PDF page 30. 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 C10-1050 2300 ± 3.5 280 127/4x M16 225/4x18 275/8x18 10 4.6 23 4 on a substation support, use PDF page 30 to compare its mounting interfaces with the structure and conductor connection. The listed Lightning impulse withstand voltage, dry [kV peak value] is 1050.

### What the drawings help you do

Download PPC_IEC_Solid-Core_A4_LQ.pdf and open PDF page 30. Find the C10-1050 2300 ± 3.5 280 127/4x M16 225/4x18 275/8x18 10 4.6 23 4 column; other tables and model rows or columns describe different insulators. The following preview page contains the associated outline diagrams. 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 C10-1050 2300 ± 3.5 280 127/4x M16 225/4x18 275/8x18 10 4.6 23 4, the source records Lightning impulse withstand voltage, dry [kV peak value]: 1050. Match that value to the conductor-support arrangement.
- Compare the C10-1050 2300 ± 3.5 280 127/4x M16 225/4x18 275/8x18 10 4.6 23 4 column on PDF page 30 with the exact fixing or stud arrangement shown in the catalogue; use the dimensions for this exact reference.
- The source also lists Switching impulse withstand voltage, wet [kV peak value]: 750. Check the project requirement against the manufacturer’s specified units and conditions.
- BIL or impulse withstand describes a short impulse test value. It is not the continuous operating-voltage rating.
