Solar PV farms and wind parks must feed clean energy into the grid through equipment that handles bidirectional power flow, harsh outdoor conditions and frequent switching — all while meeting strict grid-code reliability standards.

CHYF provides ring main unit (RMU) switchgear and gas insulated switchgear (GIS) engineered for collector substations. Sealed, compact and maintenance-light, these units manage the medium voltage interface between renewable generation and the distribution network, with vacuum and SF6 load-break switching for safe, frequent operation.
