I-Device Protection Device (SPD) ye-Overhead Line
Idivayisi Yokuvikelwa Kokuqubuka (i-SPD) ye-Overhead Line (Thermally Protected Lightning Arresters) enesivikelo esishisayo yakhelwe ukuhlinzeka ngokuvikelwa kwemigqa ephezulu yamandla kagesi, izimpahla zabathengi endlini, ama-transformers okusabalalisa, nezinye izinhlelo.
Izici:
- Isetshenziselwa ukuvikela ikhebula lokugcina / i-cablehead ngokubhekene nemiphumela yokuqhubekela phambili, okungafakwa emigqa ephezulu okuvela ephansi ye-voltage bushing insulator ye-transformer kuya endaweni yokungena kwamandla kagesi esakhiweni.
- Ukukhishwa okukhulu okuphezulu ngenxa yezinsimbi ezisindayo zensimbi ye-varistor (MOV)
- I-disconnector yokushisa ehlanganisiwe ukuthi ihluleke-iphephile futhi ivikeleke uma ilayisha ngokweqile
- Isiboniso sephutha
- Izindlu ezinqamulelayo zomlilo ezivutha umlilo nezivuthayo, ezifanele ukusetshenziswa ngaphakathi nangaphandle
- ukufakwa Easy
- Vumelana ne-EN / IEC61643-11, UL 1449 4th, IEEE C62.41, CSA C22.2
Ukukhethwa Kwamamodeli Kwedivayisi Yokuvikela Ukuqubuka Komugqa Waphezulu

Umdwebo wesayizi
Imikhiqizo ye-Prosurge Surge Protection Device Imindeni
Chofoza ukuze uhlole amadivayisi ethu wokuvikelwa okunamandla kanye neminye imikhiqizo yokuvikela umbane.
Xhumana neProsurge bese uphendula kumahora ayi-2
bheka ukuthi ukuncintisana ngentengo yethu yilezi:)
Phila uxoxe nathi ngokuchofoza inkinobho yokuxoxa ekhoneni elingezansi elingakwesokudla
Gcwalisa ifomu lokuxhumana bese uthole impendulo kumahora we-2
Kumakethe yaseNyakatho Melika, sicela uthinte
