Porcelain pin insulator SDI31

Suitable as a pin insulator for the SOT24 crossarm pin. The conductor can be tied either in the top groove or around the neck. Type-tested according to IEC 60383‑1:2023. The insulator’s semiconductive neck and threads prevent possible partial discharges with bare conductors. When installed on MV CC conductors, the semiconductive neck must be connected to the conductor potential. For MV CC conductors, composite line post insulators are recommended, e.g. SDI88.37M20.
