I-polymer insulator yokuthumela umbani
Incazelo Yomkhiqizo
>>>
Ngaphansi kwesimo esivamile sokusebenza, ukugqunywa kwesivikelo seposi sombani sidlula kuphela ku-capacitive current (izinga elincane), futhi ingxenye eyinhloko ye-Zinc Oxide resistor isesimweni sokungaqhubi ngalesi sikhathi. Ngaphezu kokuhlukaniswa kwezikhala zomoya, ama-insulators awazange adlule okwamanje, anciphisa ukuguga kwejazi elihlanganisiwe kanye nesibopheli. Ngaphezu kwalokho, ijazi eliyinhlanganisela linendawo eqinile ye-hydrophobicity kanye ne-anti-aging, futhi linokumelana okuhle kakhulu nokuvuza nokuklwebheka nokuguguleka kukagesi, futhi linamandla aphezulu okudonsa kanye nokuguquguquka. Isibambi sombani asidingi ukuhlanzwa nokuhlanzwa ngesikhathi sokusebenza. Ama-insulators okuvikela umbani anesisindo esincane, okungamaphuzu amabili we-porcelain sleeve insulators. Kulula ukufaka. Ngenxa yokuthi impahla yesivikeli, irabha ye-silicone (SR) kanye nomgogodla wesibambisi sombani zenziwa ngokucindezela okukodwa kokushisa okushisayo, akukho mgodi (oxazulula inkinga yokuvikela ukuqhuma), futhi unokuvalwa okuhle kokuvala. Ukuze kube lula ukufakwa komkhakha wamandla, ikakhulukazi ukuklama kwensimbi kusuka kumshini wokutshopa (umqhubi we-insulated overhead, ucingo olungenalutho lungaxhunywa ngokuqondile emeveni) alulimazi ucingo, ukufakwa kwe-wire, ukufakwa okulula, conductivity kagesi omuhle, futhi ngcono ukusebenza kahle.
