Surge Arrester mounting

[Tscott8201]

Does anyone know of an arrester manufacturer that makes an overhead distribution arrester that is mounted in parallel with a dead end insulator and is therefore suspended under the line instead of mounted to the dead end structure with a bracket.We require arresters on both sides of a normal open point. On a 3 phase double dead end, this means that there are 6 arresters and 3 switches that all need to be mounted on the pole and or cross arm. This causes problems with clearances and in the operation of the switches.

I am pretty sure I have seen this configuration in a catalog, but cannot find it. I have contacted Cooper (They replied back and don't have this) and Hubbell (they have yet to respond). If you know of a product that may meet our needs, please let me know who makes it.

Thanks,
Tom

MacLean makes a ZQPT transmission arrester (formerly Joslyn) designed to be mounted next to an insulator string. See

I've never seen these on distribution lines, however.

Transmission line arrester similar to the link below could be suitable for the application described.
