Genera

(H) RW9-40.5 series outdoor high-voltage current-limiting fuses (hereinafter referred to as "current limiting fuses") are outdoor high-voltage protection appliances, which are applicable to the power system with AC 50Hz and rated voltage of 35kV, and are used for overload and short-circuit fault protection of power transformers and power lines.

The fuse complies with technical standards such as high voltage AC fuses Part 2: current-limiting fuses (GB / t15166.2-2008).

Model And Meanings


Main Advantages

1. The insulating porcelain sleeve or silicone rubber composite sleeve is designed with a large creepage distance, strong pollution resistance, and environmental adaptability, and good insulation performance, which can meet the operation requirements in high-altitude areas.
2. Fuse tube replacement is simple and convenient.
3. Good fast fusing performance and large breaking capacity.
