Izintambo ezivalekile ze-PVC kanye nezintambo zihlukaniswe ngezintambo ezingafakwanga umgoqo wezintambo eziqinile, izintambo ezivalekile zocingo oluqinile, izintambo eziguquguqukayo ezingafakwanga umgoqo, izintambo eziguquguqukayo ezivalekile ezisetshenziswa kabanzi, izintambo zokufaka kanye nezintambo ezivikelwe, izintambo eziguquguqukayo ezivalekile ezisetshenziswa ngokukhethekile Izintambo, izintambo ezivalekile ze-PVC ezingashisi/ezingashisi umlilo kanye neminye imikhiqizo.
1. Inqubo yokukhiqiza evuthiwe, kulula ukuyibumba nokuyicubungula
2. Uma kuqhathaniswa nezinye izinhlobo zezinto zokuvikela ikhebula, ucingo oluvikelwe nge-PVC kanye nekhebula akubizi nje kuphela, kodwa futhi kuhlukile ngombala wobuso, ubumnyama obukhanyayo, ukuphrinta, ukusebenza kahle kokucubungula, ubulukhuni, ukunamathela komqhubi, izakhiwo zomzimba zomshini kanye nezakhiwo zikagesi zentambo uqobo, njll. Zonke izici zingalawulwa ngempumelelo; inezakhiwo ezinhle kakhulu zokuvimbela ilangabi, ngakho-ke izintambo ezivikelwe nge-PVC kanye nezintambo zingafinyelela kalula amazinga okuvimbela ilangabi achazwe ezindinganisweni ezahlukene.
3. Intambo ngokuvamile ingaphakathi kwebanga lesisindo elibekiwe. Igobolondo elisetshenziswa kuntambo yendwangu liyi-polyvinyl chloride insulation. I-wire insulation kufanele ibukeke ibushelelezi futhi icacile ngokunyathelisa okungaphezulu. Uma ibonwa kusukela ekugcineni kwentambo, i-insulation kufanele ilingane futhi ingabi yi-eccentric.

Izintambo zikagesi ze-PVC ezifakwe uthango nezimboziwe zilinganiselwe ku-0.6/1kV
Isakhiwo, isisindo, ukumelana komoya wekhebula lamandla elilodwa elingu-0.6/1kV
Izimo zokubeka ikhebula kanye nomthamo wokulayisha isikhathi eside ovunyelwe
Ukufakwa
Izinga lokushisa lokufaka akufanele libe ngaphansi kuka-0℃, uma izinga lokushisa elizungezile lingaphansi kuka-0℃, ikhebula kufanele lishiswe.
Irediyasi yokugoba yekhebula akufanele ibe ngaphansi kwezikhathi eziyi-10-15
Ngemva kokufakwa, ikhebula kufanele likwazi ukumelana nokuhlolwa kwamandla kagesi imizuzu eyi-15. 3.5Kv dc
Emoyeni
Ikhebula eliyinhloko le-sinale elihambisanayo, ibanga eliphakathi kwesikhungo sekhebula liyi-imes ezimbili (zezintambo, ezinqamula indawo yesigaba somqhubi <185mm kanye no-90 mm (zezintambo, ezinqamula indawo yesigaba somqhubi >240mm').
