Product Details
Retractable fuse HRW9
Mainly used for short circuit and overload protection of power lines and transformers, it also has the function of opening and closing no-load lines and low load currents.
Basic functions
Short Circuit Protection: Copper or silver fuses can quickly melt and interrupt short circuit current, protecting transformers and power lines.
Overload protection: achieving delayed melting due to the thermal accumulation effect of fuses, meeting the requirements of equipment overload.
Physical isolation: Drop melting tube provides a clear breaking point to ensure safe maintenance.
Benefits
Strong Weather Resistance: Ceramic insulators are UV and salt spray resistant, suitable for coastal areas and industrial pollution areas.
Seismic Design: Withstand 8 degree seismic intensity and strong wind environment (wind speed ≤ 35m/s).
Typical Application Scenarios
High-voltage power lines: 35 kV power line branch nodes and protection of the high-voltage side of the transformer.
New energy installations: Short circuit insulation of collection lines in wind farms and photovoltaic plants.
Industrial Substation: Overcurrent protection for high voltage equipment and off-load line switching in industrial and mining applications.
The HRW9 fuse, with its high reliability, flexible operation and wide adaptability to environmental conditions, has become the main protective device in the 35 kV power system. Selection requires a comprehensive assessment of line power, environmental conditions, and switching requirements.
