Okukozesa waya z’amasannyalaze kutandikira mu kyasa ekisukka mu kimu. Mu 1879, omuyiiya Omumerika T. A. Edison yazinga jute ku muggo ogw’ekikomo, n’aguyingiza mu payipu y’ekyuma, n’oluvannyuma n’agujjuzaamu omutabula gwa kolaasi okukola waya. Yassa waya eno mu New York, ng’atandikawo enkola y’okutambuza amasannyalaze wansi w’ettaka. Omwaka ogwaddako, omuyiiya w’e Bungereza Callender yayiiya waya y’amasannyalaze eyali efuuse kolaasi-empapula ezifukiddwa-eziziyiza. Mu 1889, omuyiiya Omuzungu SZ Ferranti yateeka waya ya kV 10 ey’amafuta-empapula ezifukiddwa-eziziyiza wakati wa London ne Deptford. Mu 1908, Bungereza yamaliriza okukola omukutu gwa cable ogwa kV 20. Waya z’amasannyalaze zeeyongera okukozesebwa ennyo. Mu 1911, Girimaani yassaawo waya za vvulovumenti enkulu-eza kV 60, nga kino kye kyatandika okukola waya za vvulovumenti eya waggulu-. Mu 1913, omuyiiya Omugirimaani M. Hochstedt yakola waya eziriko phase-shielded cables, ezaalongoosa ensaasaanya y’ekifo ky’amasannyalaze munda mu waya era ne zimalawo tangential stress ku insulation surface, ekyalaga ekintu ekikulu mu kukulaakulanya waya z’amasannyalaze. Mu 1952, Sweden yateeka waya za 380 kV ultra-high voltage ku kyuma kyayo eky’amasannyalaze mu bukiikakkono, nga kino kye kyasooka okukozesa waya za ultra-high voltage. Emyaka gya 1980 we gyatuukira, waya z’amasannyalaze aga vvulovumenti eya waggulu ennyo eza kV 1100 ne kV 1200 zaali zikoleddwa.
