Chimiro chose chechigadzirwa ichi ibhodhoro reporcelain riri pakutsigira, bhodhoro reporcelain repamusoro rine vacuum interrupter, uye bhodhoro repasi ibhodhoro reporcelain rinotsigira. Rakakodzera nzvimbo dzinoshanda nguva nenguva. Rine mabhenefiti ekuvhara zvakanaka, kudzivirira kukwegura, kuramba kumanikidzwa kwakanyanya, kusatsva, kusaputika, kugara kwenguva refu, kuisa nyore uye kugadzirisa. Rinonyanya kushandiswa kudzora nekudzivirira masisitimu ekunze e35KV transmission uye transformation, uye rinogonawo kushandiswa pakushanda kwakajairika uye kudzivirira magrid emagetsi emumaguta nemaruwa pamwe nemabhizinesi emaindasitiri nemigodi.
