Before using it
- For 315286-70+L, the source records Leakage Distance, Reference Standard, in. [mm]: 99 [2515]. Match that value to the conductor-support arrangement.
- Compare the 315286-70+L column on PDF page 1 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]: 152 [3861]. 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 315286-70+L on a substation support, use PDF page 1 to compare its mounting interfaces with the structure and conductor connection. The listed Leakage Distance, Reference Standard, in. [mm] is 99 [2515].
