Conditions of use
A. Elevation not more than 2000 meters
B. ambient temperature: - 40 40 +40.
C. Maximum wind speed not exceeding 35m/s
D. Power Frequency: 48Hz-62Hz
E. Lightning arrester is allowed to swing and suspension mode is considered according to tower shape.
Most suitable
1. Transmission lines with low lightning resistance and high lightning trip-out rate
2. In arid and rainless hilly and mountainous areas, it is unsuitable to maintain them.
3. Towers and areas with high grounding resistance
4. Long-span river-crossing poles and towers
5. Operating overvoltage is high, so it is necessary to restrict the situation before entering substation.
6. Seriously polluted areas
