In 35kV distribution networks, transformers and overhead lines require reliable short-circuit/overload protection; ordinary small-current fuses cannot meet 200A high-load scenarios. RW5-35/200A Outdoor Drop-out Fuse is specially designed for high-current protection. Core advantages:
-
200A High Current, Strong Breaking Capacity
- Rated current 200一個, meets protection for 35kV large/medium transformers and heavy-duty lines
- Rated short-circuit breaking 8kA, quickly cuts off short-circuit current, prevents over-level tripping and equipment burnout
- Built-in arc-extinguishing tube, fast arc quenching, no re-ignition, no chopping overvoltage, protects system insulation
-
High Outdoor Weather Resistance & Strong Insulation
- Silicone rubber composite/porcelain insulator, creepage distance 600mm, Class Ⅳ pollution, suitable for heavy pollution areas
- UV-resistant, salt spray-resistant, moisture-resistant, ice-resistant, adapts to coastal, plateau, mining areas
- 環境溫度 -40℃ ~ +40℃, altitude ≤4000m
-
Safe & Reliable, Visible Disconnection
- Fuse tube drops automatically after fuse melting, visible disconnection point, safe for maintenance
- Spherical contacts, excellent conductivity, low heat, long life, reliable contact
- Solid structure, wind-resistant, earthquake-resistant, misoperation-proof, maintenance-free outdoors long-term
-
Application Scenarios
- Primary protection for 35kV distribution transformer high-voltage side
- Sectional/branch protection for 35kV overhead lines
- Substations, pad-mounted transformers, switching stations, wind farms, solar power stations
- 35kV systems for urban/rural grid renovation, industrial parks, mines, railways
