Tech/Engineering - Electronics / Elect Eng / transformers
Italian term or phrase: asta spinterometrica
From the specs for a heavy duty transformer:

"Il codolo dei passanti sarà cilindrico di diametro 40 mm ed avente una lunghezza di 80 mm realizzato in rame, ricoperto di uno strato preferibilmente di Nichel o, in alternativa, di Argento oppure di Stagno e sarà privo delle aste spinterometriche"

This sounds like "spacer rods" or something along those lines.

Any suggestions?

spark gaps
Explanation:
https://en.wikipedia.org/wiki/Spark_gap
Spark gaps are frequently used to prevent voltage surges from damaging equipment. Spark gaps are used in high-voltage switches, large power transformers, in power plants and electrical substations. Such switches are constructed with a large, remote-operated switching blade with a hinge as one contact and two leaf springs holding the other end as second contact. If the blade is opened, a spark may keep the connection between blade and spring conducting. (The spark ionizes the air, which becomes conductive, allowing an arc to form, which sustains ionization and hence conduction.)

https://en.wikipedia.org/wiki/Spark_gap
Grandi spinterometri con separazioni di diversi metri sono utilizzati in laboratori di fisica ed ingegneria elettrica specializzati in alta tensione.
Questi dispositivi sono ampiamente utilizzati specialmente nelle linee elettriche aeree di media ed alta tensione come dispositivo di protezione dalle sovratensioni di carattere impulsivo di origine atmosferica. In questo utilizzo vengono anche chiamati scaricatori di sovratensioni.
Principalmente esistono due tipi di questi dispositivi di protezione:
A corna
Ad aste
