| TU2-10 | LPZ1, LPZ2 miganhu yenzvimbo uye LPZn | Kirasi 3 | Kazhinji yakaiswa mubhokisi rekugovera renzvimbo; kana kuiswa mumidziyo yeruzivo yekombuta, midziyo yemagetsi nemidziyo yekudzora, kana bhokisi rekuvhenekesa riri pedyo, socket box. |
| TU2-40 | miganhu yeLPZ0B uye LPZ1 zone, kana LPZ1 uye LPZ2 zone | Class2 | Inowanzo kuisirwa mubhokisi remagetsi rekugovera zvivakwa, metering box; kana kuiswa munzvimbo yekombuta, mota dzimba, imba yekudzora yekuvaka, imba yekutarisisa, maindasitiri otomatiki, imba yekugezera nedzimwe nzvimbo dzebhokisi rekugovera magetsi; zvakare inogona kuisirwa mubhokisi rekugovera bhokisi rezvitanhatu pasi pechivako, kana bhokisi rekugovera villa. |
| TU2-80 | LPZOA,LPZ0B miganhu yenzvimbo yeLPZ1 | Kirasi1 | Kazhinji yakaiswa mukuboora lined low voltage main distribution cabinet |
| TU2-1 | Inoshandiswa munzvimbo yeLPZ0A,LPZ0B | Kirasi 1 | Inowanzo shandiswa mumheni riskhigher michina sisitimu yekutanga yekutanga surge dziviriro, yakaiswa muyakajairwa bhokisi rekugovera bhokisi rekugovera, kunze kwekugovera bhokisi uye zvichingodaro. |
