Product overview
Ang RHP type HGIS electrical apparatus mao ang bag-ong tipo sa high-voltage power equipment. Gitun-an kini sa mga advantage sa GIS combined electrical apparatus sama sa compactness, high reliability, ug low operation and maintenance requirements, samtang innovatively gitun-an gihapon ang busbar isip conventional AIS arrangement alang sa on-site installation ug connection. Efektibo kini gitapos ang drawbacks nga gikasagol sa traditional AIS equipment sama sa large footprint, numerous connection points, ug high inspection and maintenance workloads.
Kini mahimong gamiton sa 40.5kV hangtod 145kV ug uban pang transmission and distribution systems sa power plants, substations, railway stations, ports, ug large industrial and mining enterprises. Particular kaayo kini nga maayo alang sa mga proyekto nga may limitadong espasyo sama sa mountainous substations ug urban substations, ug mahimong i-install indoor, outdoor, o sa rooftops.
