Before using it
- For 315216-70, the source records Leakage Distance, Reference Standard, in. [mm]: 72 [1829]. Match that value to the conductor-support arrangement.
- Compare the 315216-70 column on PDF page 2 with the exact fixing or stud arrangement shown in the catalogue; use the dimensions for this exact reference.
- The source also lists Leakage Distance, High Leak, in. [mm]: 95 [2413]. Check the project requirement against the manufacturer’s specified units and conditions.
- Leakage distance follows the insulating surface. It is different from the overall height; use the height value for the physical layout.
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 315216-70 on a substation support, use PDF page 2 to compare its mounting interfaces with the structure and conductor connection. The listed Leakage Distance, Reference Standard, in. [mm] is 72 [1829].
