(H) RW10-40.5
Drop Type Fuse Series
Outdoor / High Voltage / Current Limiting Fuse 

Technical Parameter

Altitude:  ≤ 1000m. lf the altitude is higher than 1000m, the rated insulation level should be adjusted accordingly.
Surrounding air temperature: maximum 40 ºC, minimum -25 ºC, daily temperature diference of 25K.
Humidity: Daily average relative humidity ≤ 95%, monthly average relative humidity ≤90%.
Solar radiation intensity: 0.1W/cm2.
Pollution level: not less than level d.
lce thickness: ≤ 10mm.
Outdoor wind speed (wind pressure): 35m/s (700Pa).
Earthquake tolerance (horizontal acceleration): 0.3g.

This special T type lightning arrester is designed for medium and high voltage overhead distribution lines, transformer terminals and outdoor power equipment. It helps limit lightning surge and switching overvoltage, supporting insulation coordination and overvoltage protection for power distribution networks and line protection applications.
