Before using it
- For C20-950 2100 ± 3.5 310 225/4x18 254/8x18 325/8x18 20 8.4 42 6, the source records Lightning impulse withstand voltage, dry [kV peak value]: 950. Match that value to the conductor-support arrangement.
- Compare the C20-950 2100 ± 3.5 310 225/4x18 254/8x18 325/8x18 20 8.4 42 6 column on PDF page 28 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 C20-950 2100 ± 3.5 310 225/4x18 254/8x18 325/8x18 20 8.4 42 6 on a substation support, use PDF page 28 to compare its mounting interfaces with the structure and conductor connection. The listed Lightning impulse withstand voltage, dry [kV peak value] is 950.
