Porcelain pin insulator SDI31

Porcelain pin insulator SDI31

Suitable for installation as a pin insulator on an SOT24 crossarm pin. The conductor can be tied to the top groove or the neck. Type‑tested in accordance with IEC 60383‑1:2023. The semiconductive neck and threads reduce partial discharge risk with bare conductors. Not recommended for covered conductors, as partial discharge may damage insulation. For CC, we recommend composite line post insulators, e.g., SDI88.37M20.
