Chimiro chetambo dzemagetsi emugungwa
Kazhinji, tambo yemagetsi ine conductor (cable core), insulating layer (iyo insulating layer inogona kumira nevoltage yegridi), yekuzadza uye yekudzivirira layer (yakagadzirwa semiconductor kana simbi zvinhu), sheath (kuchengetedza iyo insulation. zvinhu zvetambo) kubva mukati kuenda kunze.) uye zvimwe zvikamu zvikuru, hutano hwekushanda kwayo kwekudzivirira huchakanganisa zvakananga kushanda kwakachengeteka uye kwakagadzikana kwegadziriro yose yemagetsi.Naizvozvo, IEEE, IEC/TC18 uye mamwe mazinga epasi rose akanyatso tsanangura mashandiro etambo.
Cable conductor
Nekuda kwehunhu hwemhando yepamusoro yemagetsi conductivity uye yakakwira mechanical simba yemhangura conductor, mhangura inoshandiswa seyo conductor musimboti zvinhu mumatambo emagetsi emugungwa.Waya.Cable conductors yakakamurwa kuita compression mhando uye isiri-compression mhando zvinoenderana nemaitiro ekugadzira.Iyo compacted cable conductor ine compact structure, iyo inogona kuchengetedza zvinhu uye kuderedza mari, asi imwe chete conductor haisisiri denderedzwa renguva dzose, sezvinoratidzwa mumufananidzo 1. Mukuwedzera kune vatungamiri vane zviduku zviduku, cable conductors inowanzovharwa, iyo inogona kuve nechokwadi chepamusoro kuchinjika uye kwakasimba bendability yetambo, uye haina kutarisana nekukuvara kwekuisa insulation uye deformation yepurasitiki.Kubva pamaonero echimiro chetambo, maconductors anogona kukamurwa kuita fan-shaped, denderedzwa, gollow denderedzwa zvichingodaro.Zvinoenderana nehuwandu hwetambo conductor cores, tambo dzinogona kukamurwa kuita single-core tambo uye akawanda-core tambo.Ona GB3956 yezvirongwa zvakananga pahuwandu uye dhayamita yezita.
Cable insulation
Iyo insulation yemhando uye nhanho yetambo dzemagetsi emugungwa inoita basa rakasimba muhupenyu hwesevhisi hwetambo maererano nechimiro.Iwo matambo emagetsi emugungwa akakamurwa zvichienderana neanowanzo shandiswa ekudzivirira marudzi, sezvakaratidzwa mumufananidzo.Ukobvu uye michina zvimiro zvemhando dzakasiyana dzekuvharira tambo dzinotsanangurwawo zvakajeka muGB7594.
