surge arrester (3)
The image shows a surge arrester, an electrical device used to protect electrical equipment from voltage spikes. The arrester has a vertical, cylindrical shape with multiple gray, circular flanges stacked along its length, diminishing in size towards the top. The top of the arrester has a metal cap with a connection point, possibly for grounding. There's a white insulating bracket with a winding, indicating its mount to a structure, and at the bottom, there is a black attachment, likely for connecting to a power line. The background is plain white, highlighting the surge arrester.

Porcelain-housed Arrester

Porcelain-housed arresters, available in sizes like Y10W-72 to Y10W-228, are designed for electrical protection with a porcelain exterior. They operate effectively within -40℃ to +40℃, withstand up to 1.1kW/m² solar radiation, and altitudes up to 2,000m. Suitable for 48-62 Hz power supplies, they ensure safety under continuous operating voltages, endure earthquake intensities up to 8 degrees, and resist winds up to 35 m/s.
