Ito ay may mga katangian ng simple structure, flexible operation, reliable interlocking, at convenient installation. Ito ay maaaring magbigay ng satisfactory technical solutions para sa iba't ibang aplikasyon at users.

Karakteristik

• 11kV-class SF₆ high-efficiency insulation: Gumagamit ng SF₆ gas bilang insulating medium, na may insulation strength na maipapadala nang maayos sa 11kV high-voltage level at excellent arc-extinguishing performance. Ito ay maaaring stable na i-block ang current leakage sa high-voltage environments, na nagbabawas ng risks ng mga faults tulad ng short circuits at flashovers, at nag-aasikaso ng reliable operation ng medium at high-voltage power grids.

• Compact high-voltage adaptive design: May small at compact structure na may maliit na footprint, na siyang partikular na angkop para sa space-constrained 11kV high-voltage distribution scenarios tulad ng urban distribution stations at industrial parks. Ito ay simplifies ang installation layouts habang nag-iimprove ng site utilization.

• Multiple safety protection mechanisms: Nakakamit ng complete mechanical at electrical interlocking devices upang maipatupad ang strict prevention ng misoperations at incorrect switching; built-in SF₆ gas leakage monitoring system na nagbibigay ng real-time warnings ng leakage risks. Ito ay sumasailalim sa international high-voltage equipment safety standards, na nag-aasikaso ng safe operation at maintenance.

• Low-maintenance at long-life characteristics: Ang fully sealed gas chamber design ay effective na nag-iisolate ng dust, moisture, at corrosive substances, na nagbabawas ng erosion ng internal components ng external environment. Ito ay nag-aasikaso ng long-term maintenance-free operation na may service life na higit sa 20 taon, na nagbabawas ng whole-life-cycle cost.

• Flexible power distribution compatibility: Suportado ng multiple wiring methods tulad ng ring network at radial types, at maaaring mabilis na konektado sa 11kV-class transformers, cables, at iba pang equipment. Ito ay sumasailalim sa topological requirements ng iba't ibang medium at high-voltage distribution networks, na nag-aasikaso ng diverse power supply scenarios kasama ang urban power grids at large industrial plants.

• Balance of environmental protection at economy: Ang SF₆ gas ay recyclable at reusable, na nagbabawas ng resource waste; ang equipment ay may mababang operating energy consumption, at ang long-term usage costs ay controllable, na nag-aasikaso ng balance ng environmental protection requirements at project economic benefits.
