Classification:
Keywords: dry-type transformer series | oil-immersed power transformer series | special transformer series | box-type transformer series
Immediate ConsultationProduct Introduction
XGN2 indoor AC metal-enclosed switchgear (referred to as switch cabinet) is used in three-phase AC 50Hz systems below 12kV for receiving and distributing electrical energy, especially suitable for frequent operation scenarios. Its bus system is a single bus (which can derive a single bus with bypass and double bus structure).
XGN2 box-type fixed AC multi-closed switchgear is a plateau-type product derived from ordinary switch cabinets, suitable for use in high-altitude areas.
Product Features
This switch cabinet complies with national standard GB3906 "3-35kV AC metal-enclosed switchgear" and international standard IEC298 requirements, and has a complete "five prevention" interlocking function.
The main switch of this switch cabinet uses ZN28A-10 series vacuum circuit breakers with CD17 series electromagnetic and CS17/CS19 series spring operating mechanisms. According to user needs, ZN28-10, ZN73 and other integrated circuit breakers can also be used. The isolating switch uses GN30-10 large current isolating switch and GN30-10 rotary large current isolating switch series products.
