Hashingiwe ku rugero rw’umuriro, zishobora guca mu mirongo y’umuriro uri hagati n’uwuri hasi (35 kV n’inyuma), imirongo y’umuriro munini (hejuru ya 110 kV), imirongo y’umuriro munini cane (275-800 kV), n’imirongo y’umuriro munini cane (1000 kV no hejuru). Ikindi kandi, zishobora guca mu mirongo ya AC n’iya DC zishingiye ku nzira y’umuriro.
Bishingiye ku bikoresho vyo kwikingira
1. Intsinga z’amashanyarazi zikingiwe n’amavuta-impapuro: Intsinga z’amashanyarazi zikingiwe n’amavuta-impapuro ni zo zimaze igihe kirekire zikoreshwa. Biratekanye, ni ivyo kwizigirwa, biramara igihe kirekire kandi ntibizimvye. Intambamyi yabo nyamukuru ni uburebure bw’ugushiraho imipaka. Iterambere ry’ubuhinga bwo gukingira impapuro zitagira amazi zitonyanga-ratorera umuti iyo nzira y’uburebure, bituma imirongo y’impapuro zikingira amavuta-ishobora kubandanya ikoreshwa cane.
2. Intsinga z’amashanyarazi zikingiwe n’ipulasitike-: Intsinga z’amashanyarazi zifise igipande c’ipulasitike gikingira. Ivyuma bikoreshwa cane ni nk’ivyo bita polyvinyl chloride, polyéthylène, n’ivyo bita polyéthylène bifatanye n’umusaraba-. Intsinga z’ipulasitike zifise ubuhinga bworoshe, ziroroshe gukora no gutunganya, ziraremereye, kandi ziroroshe gushiramwo no gushiramwo ata n’aho zigarukira ku burebure bwo gushiramwo. Ni co gituma zikoreshwa cane ku nsinga z’umuriro ziri hagati n’iziri hasi kandi ziriko ziratera imbere mu gusubirira intsinga z’impapuro zifise amavuta y’umuriro-. Intambamyi yayo nini cane ni ikintu co gusenyuka kw’ibihimba vy’umubiri (dendrite), ivyo bikaba bigabanya ikoreshwa ryayo ku bijanye n’amashanyarazi menshi.
3. Intsinga y’amashanyarazi y’imipira-ikingira: Igipande c’umuyagankuba gikozwe mu mipira ifatanijwe n’ibintu bitandukanye bifatanya, ivyo bikaba bivangwa neza, bikajanwa ku ntumbero y’umuyagankuba, hanyuma bikajanwa n’ubushuhe-. Ni yoroshe kandi irashobora guhinduka, ivyo bikaba bituma ibereye gushirwa mu bibanza bifise ukwinyiganza kenshi be n’ibice bitobito vy’ugupfukama.
Ivyuma vy’imipira bikoreshwa mu gukingira umuriro harimwo imipira kavukire-styrène-butadiene, imipira ya éthylène propylène, n’imipira ya butyl.
Gushirwa mu migwi hakurikijwe urugero rw'umuriro:
1. Intsinga y’umuriro muto-: Ibereye gushirwa ku mirongo y’ugutanga no gukwiragiza AC 50Hz ifise umuriro ugereranijwe na 3kV n’inyuma, kugira ngo ushiremwo ubushobozi.
2. Intsinga z’umuriro uri hagati- n’uwuri hasi-: (muri rusangi 35kV n’inyuma): Intsinga zikingira PVC, intsinga zikingira polyethylene, intsinga zikingira polyethylene zifatanye n’umusaraba-, n’ibindi.
3. Intsinga z’umuriro mwinshi-: (muri rusangi 110kV n’irenga): Intsinga za PE n’intsinga z’umusaraba-zikingira polyethylene, n’ibindi.
4. Intsinga z’umuriro mwinshi cane: (275{5}}800kV){4}} Intsinga z’umuriro mwinshi cane: (1000kV n’iyirengeye).
