HRW12 12/24 kV outdoor switch-fuse
Specially designed for short circuit and overload protection of distribution lines and transformers, with the function of splitting and combining load currents, suitable for protecting power equipment on overhead lines and in harsh environments
Basic functions
Short Circuit Protection: The fuse melts quickly, isolating short circuit currents and protecting distribution transformers and transmission lines.
Overload protection: achieving delayed melting due to the thermal accumulation effect of fuses, corresponding to the overload characteristics of the equipment.
Load current switching: Supports manual switching of rated load current (≤ 200A), with isolating switch function.
Benefits
High Reliability: Elastic auxiliary contact paired with arc-extinguishing cover enhances the stability and safety of opening and closing.
Long service life: Mechanical service life ≥ 2000 opening and closing operations, suitable for frequent operating scenarios.
Typical Application Scenarios
Distribution transformer protection: Short circuit and overload protection on the high voltage side of 12/24 kV transformers.
Branches of overhead power lines: short circuit insulation and load switching on branches of distribution networks.
Protection against adverse conditions: protecting power lines in high mountain, windy and coastal areas
The HRW12 fuse, with its optimized arcing characteristics, high mechanical life and environmental adaptability, has become the main device for short-circuit protection and load switching in 12/24 kV distribution networks, suitable for power grid scenarios with high stability and safety requirements.
