Before using it

For C12.5-1050 2300 ± 3.5 295 127/4x M16 225/4x18 254/8x18 275/8x18 12.5 5.75 28.75 6, the source records Lightning impulse withstand voltage, dry [kV peak value]: 1050. Match that value to the conductor-support arrangement.
Compare the C12.5-1050 2300 ± 3.5 295 127/4x M16 225/4x18 254/8x18 275/8x18 12.5 5.75 28.75 6 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.

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 C12.5-1050 2300 ± 3.5 295 127/4x M16 225/4x18 254/8x18 275/8x18 12.5 5.75 28.75 6 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.
