The RW12-12-4 porcelain fuse cutout is an upgraded high-performance outdoor high-voltage protection device, belonging to the RW12 series optimized model, specially designed for 10kV/12kV overhead distribution lines and distribution transformers. It inherits the reliable performance of the RW12 series, adopts high-strength porcelain insulation housing, and is optimized for structural stability and anti-pollution performance, which can effectively protect power equipment from overload and short-circuit faults. As a cost-effective and reliable protection solution, it is widely used in rural and suburban power grids, industrial and mining enterprises, distributed power generation systems (such as photovoltaic and wind power), and can also adapt to harsh outdoor environments such as coastal salt fog and mountainous strong wind areas.
Compliant with international standards such as IEC 60282-2 and national standards GB/T 15166.3, the product has passed strict type tests (including temperature rise, impulse withstand voltage, short-circuit breaking, etc.), ensuring stable operation in harsh outdoor environments such as high temperature, low temperature, humidity and salt fog. It has excellent mechanical performance and electrical insulation, and its service life can reach more than 15 years under normal working conditions.
