Kushandiswa kwetambo dzemagetsi kwakatanga makore anopfuura zana. Muna 1879, muumbi wekuAmerica TA Edison akaputira jute netsvimbo yemhangura, akaipinza mupombi yesimbi, ndokuizadza nemusanganiswa weasphalt kugadzira tambo. Akaisa tambo iyi muNew York, achipayona pasi pevhu kutumira magetsi. Gore rakatevera, mugadziri weBritish Callender akagadzira asphalt-bepa rakaiswa pamuviri-insulated power cable. Muna 1889, mugadziri wekuBritain SZ Ferranti akaisa mafuta e10 kV{13}}bepa rakaiswa pamuviri{{14}netambo yakavharidzirwa pakati peLondon neDeptford. Muna 1908, UK yakapedzisa 20 kV cable network. Tambo dzemagetsi dzakawedzera kushandiswa zvakafara. Muna 1911, Germany yakaisa 60 kV high{{22}tambo dzemagetsi, zvichiratidza kutanga kwekugadzirwa kwetambo dzepamusoro{23}dzemagetsi. Muna 1913, muvambi wekuGermany M. Hochstedt akagadzira chikamu-tambo dzakavharidzirwa, dzakanatsiridza kugovera kwemagetsi mukati metambo uye kubvisa kushushikana kwakanyanya panzvimbo yekudzivirira, zvichiratidza chiitiko chakakosha mukugadzirwa kwetambo dzemagetsi. Muna 1952, Sweden yakaisa 380 kV ultra-tambo dzemagetsi akakwira panzvimbo yayo yekuchamhembe, zvichiratidza kutanga kushandiswa kwetambo dzemagetsi epamusoro-pamusoro. Pakazosvika makore ekuma1980, 1100 kV ne1200 kV ultra{{37}tambo dzemagetsi epamusoro dzakanga dzagadzirwa.
