Abstract (en)

[origin: CA2151825A1] A surge voltage protector (1) for high voltage has a porcelain housing (2) with safety shields (3, 4, 7, 8). In the central area along the longitudinal axis of the surge voltage protector (1), safety shields (3) with a larger diameter may alternate with safety shields (4) having a smaller diameter. The surge voltage protector (1) has blow-out apertures (5) at its ends, and gas under high pressure flows out of these apertures in the event of a-short-circuit current. To protect the safety shields from damage, the safety shields (7, 8) that are closest to the blow-out apertures (5) are constructed with smaller diameters than the other safety shields.
