Pfungwa yekutakura shongwe, transmission conductors inotsigirwa nezvikamu zveshongwe dzekutumira. Mitsetse yemagetsi yakakwira inoshandisa “shongwe dzesimbi,” nepo mitsetse yakaderera yemagetsi, seyanoonekwa munzvimbo dzinogara vanhu, inoshandisa “matanda emapuranga” kana “matanda ekongiri.” Pamwe chete, ivo vakaungana vanonzi "shongwe." Mitsetse yemagetsi yakakwira inoda chinhambwe chakakura chekuchengetedza, saka inoda kumiswa pahurefu hwakakura. Nhare dzesimbi chete dzinokwanisa kutsigira makumi ematani emitsetse. Danda rimwe chete harigone kutsigira kureba kana huremu hwakadaro, saka mapango anowanzo shandiswa kune yakaderera voltage mazinga.

Pane kazhinji nzira mbiri dzekuona iyo voltage level:

1.Pole nhamba plate yekuziva nzira

Pashongwe dzemitsetse yakakwira-voltage, mapolen number plates anogaroiswa, zvichinyatsoratidza zvakasiyana-siyana mazinga akaita se10kV, 20kV, 35kV, 110kV, 220kV, uye 500kV. Nekudaro, nekuda kwekugara kwenguva refu kumhepo nezuva kana kwezvakatipoteredza, mahwendefa enhamba anogona kusajeka kana kunetsa kuwana, zvinoda kunyatsotariswa kuti uverenge zvakajeka.

2.Isulator tambo yekuziva nzira

Nekutarisa huwandu hwetambo dze insulator, iyo voltage level inogona kuve yakatemwa.

(1) 10kV uye 20kV mitsetse inowanzoshandisa 2-3 insulator tambo.

(2) 35kV mitsetse inoshandisa 3-4 insulator tambo.

(3) Pamitsetse ye110kV, 7-8 insulator tambo dzinoshandiswa.

(4) Pamitsara ye220kV, nhamba yetambo dze insulator inowedzera kusvika 13-14.

(5) Pachiyero chepamusoro-soro che500kV, nhamba yetambo dze insulator dzakakwira kusvika pa 28-29.
