Hot - urupapuro rw’icuma ruteye igomwe: Uruhande rw’ivyuma vy’agaciro n’ibigereranyo vyerekana amashurwe y’urubura ({1}} nk’amashurwe ya zinc (diameter 1{3}}5mm), mu gihe uburebure bw’icuma c’agaciro ata n’ifeza - Ifeza, n’igice c’ivyuma bitandukanye ({6}} gray) kiboneka ku bice vyo ku ruhande. Bimeze nk’ibiteye ubwoba ku bijanye n’ugukorako, kandi ibintu bimwebimwe birafise amavuta arwanya umugese ku ruhande.
Electro- urupapuro rw’icuma: Uruhande rw’ifeza rukayangana- y’umukara, ata n’amashurwe ya zinc, afise ubushobozi bwinshi. Igipande ca zinc ku bice vyo mu ruhande ni gito cane (hafi kitaboneka), kandi ibice bimwebimwe vyerekana ibara ry’umuhondo ry’umuco inyuma y’uguvugwa n’uguca (chromate dication).
