RMR 24kV RMU: SF6-insulated, stainless steel-tanked (≤0.1% annual leakage, 30y life), non-extensible/extensible/modular, safe, ideal for power distribution.
Discover maintenance-free solid insulated ring main units for 12kV solar plants – reliable, compact, and built for renewable energy.
RMU berinsulasi gas OMR memiliki semua bagian aktif bertegangan tinggi yang disegel secara hermetis di dalam tangki gas baja tahan karat. Unit ini dirakit dan diuji sepenuhnya di pabrik, dengan tapak yang ringkas serta kebal terhadap debu dan kelembapan luar ruangan.
GIS RMU luar ruang ini dapat disediakan untuk sistem tegangan menengah 11kV, 22kV, dan 33kV, dengan kombinasi bay yang fleksibel untuk modul ring-in, ring-out, dan proteksi trafo.
Mekanisme pegas manual merupakan standar untuk operasi lokal. Aktuator bermotor dapat dipilih untuk mendukung pembukaan/penutupan jarak jauh, dipasangkan dengan indikator gangguan dan sistem SCADA untuk manajemen gangguan otomatis.
Struktur tangki tertutup mengisolasi komponen tegangan tinggi internal dari polusi eksternal. Selungkup anti-korosi merupakan standar, cocok untuk lingkungan kabut garam pesisir, kelembapan tinggi, dan lokasi luar ruangan yang berdebu.
Indikator lintasan gangguan, monitor densitas gas, dan modul komunikasi bersifat opsional. Perangkat ini memungkinkan penentuan lokasi gangguan, pelacakan status gas, dan pengunggahan data jarak jauh ke sistem otomasi distribusi.
