Nidaamka beddelka kaydadka khaaska ah-fudud in lagu beddelo kaydadka iyada oo aan waxyeello u geysan saldhigga SPD.

Calaamadeynta heerka kala-goynta 'varistor' (calaamadda cagaaran-casaanka cagaaran) oo muujineysa bedelka lama huraanka ee wali kartoon shaqeynaya kahor guuldaradeeda ugu dambeysa iyo furitaanka SPD.
