Product Overview
The FZW28 outdoor high-voltage vacuum sectionalizer is an intelligent protection switchgear specifically designed for 10kV outdoor distribution lines. It integrates vacuum arc extinction, fault detection, and intelligent opening/closing functions, primarily used for branch line protection and zone substation end-point protection on overhead lines. It can accurately identify transient and permanent line faults, automatically isolate fault sections, avoid upstream line tripping and power outages, effectively reduce the scope of outages, and improve distribution network reliability. It is a core device for rural and urban network upgrades and outdoor distribution branch protection.
The product features a fully sealed outdoor structure, vacuum arc extinguishing insulation, and a maintenance-free design. It strictly adheres to high-voltage power industry standards, offering pollution resistance, water resistance, and aging resistance, adapting to complex outdoor weather conditions. It boasts high breaking capacity, reliable operation, intelligent maintenance, and high cost-effectiveness, widely used in outdoor overhead distribution, industrial parks, rural power grids, and zone substation protection scenarios.
Operating Environment
1. Ambient temperature: -40℃ to +55℃, withstands extreme outdoor temperatures and day-night temperature variations.
2. Altitude: ≤1000m (reinforced insulation available for high-altitude areas, adaptable to plateau distribution environments).
3. Relative humidity: ≤95% (at 25℃), fully sealed against moisture and condensation, preventing internal insulation failures.
4. Installation site: Outdoor overhead lines, distribution zones, suburban and rural power grids, outdoor lines in industrial parks. No severely corrosive gases or explosive dust.
5. Protection level: IP65, fully sealed against dust and water, resistant to rain, sand, high temperatures, and severe cold.
6. Installation requirements: Pole-mounted hanging installation, securely fixed with reliable grounding, maintaining safe insulation distances. No violent vibration or impact.
