This variable frequency power cabinet is the core equipment of the shore power system for ports and docks. It is specially designed to convert conventional onshore grid power into stable, high-quality power that meets the operating requirements of moored vessels.

This shore‑based socket box is installed on docks/berths, specially designed to supply electric power from on‑shore grid to moored vessels (cold‑ironing).

Epoxy resin post insulators are cast‑type solid insulation components made of high‑quality epoxy resin. They provide mechanical support, insulation and creepage distance for busbars and live parts inside medium‑voltage switchgears. Good mechanical strength (bending failure load), high partial‑discharge resistance, excellent hydrophobicity and anti‑tracking performance. Suitable for indoor use up to 12 kV, complying with IEC 60243‑1, IEC 60695. Custom height, creepage distance and mounting dimensions available.
