Gukoresha insinga z'amashanyarazi byatangiye mu binyejana byinshi. Mu 1879, Umunyamerika wavumbuye TA Edison yazengurutse jute mu nkoni y'umuringa, ayizingira mu muyoboro w'icyuma, hanyuma ayuzuza uruvange rwa asfalt kugira ngo akore umugozi. Yashyizeho uyu mugozi i New York, abanza gukwirakwiza amashanyarazi mu nsi. Umwaka ukurikira, Callender wavumbuye Ubwongereza yahimbye asfalt - impapuro zatewe - insinga z'amashanyarazi. Mu 1889, SZ Ferranti wavumbuye umwongereza yashyizeho amavuta ya kV 10 - impapuro zatewe - insinga yatewe hagati ya London na Deptford. Mu 1908, Ubwongereza bwarangije umuyoboro wa kabili 20 kV. Intsinga z'amashanyarazi zagiye zikoreshwa cyane. Mu 1911, Ubudage bwashyizeho insinga za voltage 60 kV -, byerekana intangiriro yiterambere ry’insinga ndende -. Mu 1913, umudage wavumbuye umudage M. Hochstedt yateje icyiciro - cyakingiwe insinga, cyateje imbere ikwirakwizwa ry’umuriro w'amashanyarazi muri kabili kandi gikuraho imihangayiko igaragara hejuru y’izuba, ibyo bikaba ari intambwe ikomeye mu iterambere ry’insinga z'amashanyarazi. Mu 1952, Suwede yashyizeho insinga z'amashanyarazi 380 kV ultra - ku rugomero rw’amashanyarazi rwo mu majyaruguru, ibyo bikaba ari byo byashyizwe mu bikorwa bwa mbere insinga za ultra -. Mu myaka ya za 1980, insinga z'amashanyarazi zifite ingufu za 1100 kV na 1200 kV ultra -.
