Isifinyezo

Isigaba sesithathu esihlanganisiwe sombani wokubamba uhlobo olusha lombani olusetshenziswa kakhulu ukuvikela i-transformer, switch, bas bar, electrometer, parallel compensating capacitor Ku-35kV system kagesi, futhi ingakhawulela amandla amaningi omoya, i-vacuum circuit breaker, isigaba emhlabeni, isigaba ngesigaba.
Isigaba esithathu esihlanganisiwe se-lightnihg arrester siqukethe ababani bethu bonyazi ngohlobo lwezinkanyezi ezine, Ngakho-ke itcan ukuvikela isigaba ngasinye emhlabeni nesigaba ngesigaba kusuka ku-over-voltage, ngenxa yohlaka lwayo oluhlakaniphile, ukusebenza kwalo kulingana nababamba umbani abayisithupha, futhi ukuxazulula inkinga ukuthi ababamba umbani bangakwazi 'ukuvikela isigaba sigaba kahle kakhulu. Ukuboshwa kombani okuhlanganisiwe okungaba yigebe noma kungabikho uchungechunge.
