Product overview
Ang kagamitan ng RHP type HGIS ay isang bagong uri ng high-voltage power equipment. Ito ay nagsasagawa ng mga pakinabang ng GIS combined electrical apparatus, tulad ng kompakto, mataas na reliabilidad, at mababang pangangailangan sa operasyon at pag-aalamin, habang naisipang naiiral ang busbar bilang isang regular na AIS arrangement para sa on-site installation at koneksyon. Ang disenyo na ito ay epektibong naggagamot ng mga kadahilanan na may kaugnayan sa tradisyonal na kagamitan ng AIS, kasama ang malaking footprint, maraming puntos ng koneksyon, at mataas na trabaho sa inspeksyon at pag-aalamin.
Ito ay angkop para sa 40.5kV hanggang 145kV at ibaba na transmission at distribution systems sa mga power plants, substations, railway stations, ports, at malalaking industriyal at mining enterprises. Ito ay partikular na angkop para sa mga proyekto na may limitadong espasyo tulad ng mga substation sa bundok at urban substations, at maaaring i-install sa loob, labas, o sa bubong.
Product Component

Mga pangunahing tampok
Totoong Solusyon sa mga Hamon sa Operational Reliability ng Disconnector/Earthing Switches;
Advanced Self-Blast Interruption at Modular Structure para sa Mas Mataas na Reliability;
Ang pagtanggal o masiglang pagbawas ng disc-type insulators para sa mas mataas na reliability;
