Kufotokozera Kwachidule:

Zw7-40.5 mndandanda wakunja wapamwamba wa voliyumu wowononga dera ndi magawo atatu AC 50Hz. Zosinthira zakunja zamphamvu kwambiri zokhala ndi voliyumu ya 40.5Kv. Yokhala ndi makina ogwiritsira ntchito masika kapena ma electromagnetic opareshoni, imatha kuwongolera kutali ndi kutseka kwamagetsi, komanso kusungidwa pamanja mphamvu, kulekanitsa ndi kutseka pamanja. Kapangidwe kake kakukwaniritsa zofunikira za GB1984 "AC high voltage circuit breaker" mulingo wadziko lonse, ndikukwaniritsa zofunikira za IEC62271:100 "High voltage AC circuit breaker" International Electrotechnical Commission standard. ZW7-40.5 vacuum circuit breaker imagwiritsidwa ntchito kwambiri poyang'anira ndi kuteteza magetsi akunja a 35KV ndikusintha, komanso ndi oyenera kugwira ntchito bwino komanso chitetezo chachifupi chamagetsi akumidzi ndi kumidzi komanso mabizinesi ogulitsa mafakitale ndi migodi. Mapangidwe onse a mankhwalawa ndi mtundu wa mzati wa porcelain; Botolo lapamwamba la porcelain lili ndi chipinda chozimira cha vacuum arc, ndipo botolo la porcelain lakumunsi ndi botolo la porcelain. Oyenera ntchito pafupipafupi. Ili ndi mawonekedwe a kusindikiza kwabwino, kukana kukalamba, kukana kuthamanga kwambiri, kusayaka, kuphulika, kuphulika, moyo wautali wautumiki, kukhazikitsa kosavuta ndi kukonza.
