Layin hatimin waje na babban ƙarfin lantarki yumbu capacitors, musamman Layer epoxy, yana aiki ba kawai azaman kayan rufewa ba har ma yana tasiri ga ƙimar gabaɗaya da halayen capacitor kanta.

 

Na farko kuma mafi mahimmanci, haɗin kai tsakanin kwakwalwan yumbura da ma'aunin epoxy shine mahimmin haɗin gwiwa. Rashin haɗin gwiwa na iya haifar da ƙananan ƙarfin aiki. Don haka, girman waɗannan rukunin yanar gizon haɗin kai kai tsaye yana shafar amincin Layer Layer, tare da haɗin gwiwa mai yawa wanda ke haifar da ƙarami na juzu'i.

 

Na biyu, yayin aiki na yumbu capacitors a ƙarƙashin babban ƙarfin lantarki ko yanayin fitarwa, damuwa mai haifar da zafi yana faruwa. Wannan maimaita matsananciyar zafi yana haifar da haɓakawa da rashin daidaituwa tsakanin ainihin abubuwan da ke haifar da resin delamination. Ƙarfin watsar da iskar gas a cikin capacitor yana raguwa sosai, yayin da damuwa a kan Layer epoxy yana ƙaruwa sosai, yana sa capacitor ya zama mai saukin kamuwa da gazawa.

 

Bugu da ƙari kuma, an yarda da cewa bayan tsarin sintering a yanayin zafi mai yawa, masu amfani da wutar lantarki suna buƙatar lokacin dawowa don rage damuwa na zafi ta hanyar matakai na halitta. Tsawon lokacin dawowa, mafi girman ikon capacitors don jure tashin hankali, yana tabbatar da inganci mafi girma. Misali, kwatankwacin sabbin capacitors da aka yi da wadanda suka yi kusan watanni biyu na farfadowa, na karshen yana nuna juriya mai yawa ga wutar lantarki, samun matakan 80kV ko fiye ko da lokacin da aka gwada a 60kV da farko.

 

Haka kuma, zaɓin kayan epoxy na iya yin tasiri ga aikin capacitors a yanayin zafi daban-daban. Wasu masu ƙarfin yumbu mai ƙarfi na iya samun raguwar tasiri a ƙananan yanayin zafi. Misali, idan aka fuskanci yanayin sanyi mai ƙasa da -30 ma'aunin celcius, fashe na iya tasowa saboda rashin kyawun kayan epoxy a irin wannan ƙananan yanayin zafi ko rashin jituwa tare da faɗaɗa da ƙanƙantar kwakwalwan yumbu. Sakamakon haka, rashin daidaituwa da damuwa da matsanancin sanyi ke haifarwa ya kasa rage ƙarar zuwa daidai wannan, yana haifar da nau'in tsari.

 

Ta hanyar magance waɗannan abubuwan da tabbatar da ingancin ƙirar epoxy, masana'antun na iya haɓaka aikin gabaɗaya da amincin babban ƙarfin wutar lantarki.
