Ubuvuzi bwo ku ruhande n'uburinganire bw'urutsinga rw'umuringa

Kugira ngo intsinga z’umuringa zikore neza, akenshi zica ziterwa n’ivyo gupfuka: intsinga z’umuringa zipfutswe n’ibiti- (zifise igice c’ibiti ku ruhande) zituma zishobora gutera neza kandi zikabuza gutera ivyatsi, kandi zikoreshwa cane mu bipimo vy’ibikoresho vy’ubuhinga bwa none. Intsinga y’umuringa ipfutse nickel- (ifise igice ca nickel) ihuriza hamwe ubushobozi bwo guhangana n’ubumara n’ubushobozi bwo guhangana n’ugusambuka, bikaba bituma ibereye ahantu hari ubushuhe bwinshi canke ahantu hashobora gusenyuka.
Ku bijanye n’ugukingira, umugozi w’umuringa uzingiwe na PVC, XLPE (polyethylene ifatanye n’umusaraba), umupira canke fluoroplastics, bikaba biwushoboza guhura n’ingero zitandukanye z’umuriro (kuva ku nguvu ntoyi gushika ku nguvu nyinshi cane) be n’ibidukikije (kuva ku nguvu zikomeye cane canke zikomeye cane).
