Aplikasi
Actastheprotectingandcontrollingunitfororgridequipmentsandindustrialminingenterprises'equipments,LW8-40.5 type outdoor SF6 circuit breaker minangka piranti ruangan sing digunakake ing AC 50HZ telung fase 40.5KV sistem daya.Iku ditrapake kanggo lokasi sing perlu Kerep operasi ing dirating saiki utawa ing sirkuit cendhak bola-bali on/off.Ngandhut trafo saiki kanggo pangukuran lan pangayoman, bisa langsung ngganti SW2-35 kurang mbobol sirkuit lenga lan macem-macem jinis mbobol sirkuit lenga karo krenjang transisi.Uga bisa digunakake minangka dasi mbobol lan ngoper kahanan klompok kapasitor karo CT14 jinis mekanisme spring.
