TheZn85-40.5 IndoorPandhuan sirkuit sirkuitApa piranti pangayoman daya medium medium (MV) sing dirancang kanggo telung phase AC 50Hz, 40.5kv sistem listrik. vacuum circuit breakerdelivers high-performance switching capability for load current, overload current, and fault current scenarios. Its compact structure, outstanding electrical and mechanical properties, and long service life make it a preferred solution for reliable, frequent operations under harsh conditions.
Fitur utama saka zn85-40.5 breaker sirkuit vakum
- Desain Arc-Extinguishing Advanced: Kamar mateni Arc kanthi mandhiri silinder insulasi epoksi, njamin insulasi listrik sing apik banget, lan creepage sing kurang, lan suda volume produk.
- Compact and User-Friendly Layout: The vacuum interrupters, drive mechanisms, and primary conductor systems are vertically arranged in an upper-lower configuration, which reduces the device’s depth and makes it suitable for modern compact switchgear cabinets.
- Maintenance-Free Solid-Sealed Pole: The insulating cylinder integrates vacuum interrupters and current path components into one solid-sealed structure. This design allows for long-term operation without the need for routine maintenance.
- Flexible Installation: The breaker is available in both fixed and withdrawable configurations, suitable for XGN-40.5, KYN61 switchgear, and compact box-type substations.
- Compliant with Standards: Fully compliant withIEC 62271-100, ensuring reliable performance in medium voltage switching applications globally.
