Product Description

GENERAL

(H) RW10 - 40.5 outdoor high-voltage current limiting fuse (hereinafter referred to as "current limiting fuse") is an outdoor high-voltage protection appliance, which is applicable to the power system with AC 50Hz and rated voltage of 35kV and is used for overload and short circuit fault protection of power transformers and power lines.

The fuse shall comply with GB/T 15166.2-2008 High Voltage AC Circuit Breakers - Part 2: Current Limiting Fuses and other technical standards.


MODEL AND MEANINGS

USAGE ENVIRONMENTAL CONDITIONS
1. Altitude: ≤ 1000 m. If the altitude is higher than 1000m, the rated insulation level shall be corrected accordingly.
2. Ambient air temperature: maximum 40ºC, minimum - 25ºC, daily temperature difference 25k
3. Temperature: daily average relative humidity ≤ 95%, monthly average relative humidity ≤ 90%
4. Solar auxiliary radiation intensity: 0.1W/cm²
5. Icing thickness: not more than 10mm
6. Earthquake resistance: horizontal acceleration 0.3g
7. Outdoor Wind speed (Wind pressure): 35m/s (700Pa)
8. Pollution level: e-level


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.
