1.Uhlaka

I-VSM-12 series unomphela uzibuthe-uhlobo lwasendlini high voltage vacuum circuit breaker iyisigaba ezintathu AC 50Hz, voltage ukalwe 12kV endlini switch imishini. Kufakwe ngendlela enozibuthe ehlala njalo yenkampani yethu ucwaningo nokuthuthukiswa kwamabhizinisi ezimboni nezimayini, ukuphehla ugesi kanye nezindawo zesiteshi esincane njengezinhloso zokulawula nokuvikela ugesi. Umkhiqizo onokwethenjelwa okuphezulu kanye nezici zempilo ende, ikakhulukazi ezindaweni ezinezimo ezibucayi, njengokusebenza njalo, ukuphindaphinda kwe-short-circuit breaking current.
