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.
Epoxy resin contact boxes are cast insulating housings installed around the moving/static contacts of vacuum circuit breakers in medium‑voltage switchgears. They insulate the contact area, increase creepage distance, prevent phase‑to‑phase and phase‑to‑earth flashover, and guide the moving contact path. Optimized inner shape for good electric‑field distribution, low partial discharge, high resistance to arcing damage. Complies with IEC 60243‑1.
Epoxy resin wall bushings are cast insulation components used where busbars pass through the metal partition walls of switchgear compartments. They provide reliable insulation between live busbar and earthed metal panel, and guarantee required creepage distance both inside and outside the partition. High mechanical strength, low partial discharge, excellent surface insulation performance. Complies with IEC 60137.
MV combined current‑voltage sensors are epoxy‑cast measuring components for 12 kV 24kv and 36kv switchgears, replacing conventional CT/PT. They convert primary current and voltage into low‑level analog or digital signals for protection, metering and monitoring. Features high accuracy class, wide linear range, good transient performance, small size and light weight. Complies with IEC 60044‑7 / IEC 60044‑8.
