Transformer Yokwera Magawo Atatu ya 2500kVA
Mafotokozedwe Akatundu
JZP Transformer ndi katswiri wopanga ma transformer okhala ndi mndandanda wa UL ndi ziphaso za milingo yamagetsi mpaka 44kV, zomwe zimapereka mitundu yonse ya ma transformer otsimikizika a UL. Chaka chilichonse, timatumiza ma transformer ambiriwa ku United States ndi Canada. Popeza tili ndi luso la IEEE/ANSI, CSA, DOE, NEMA, ndi miyezo ina, gulu lathu limaonetsetsa kuti likutsatira zofunikira zosiyanasiyana zolamulira. Kuphatikiza pa chiphaso cha UL, tilinso ndi ziphaso za CSA, MF, CESI, ndi malipoti oyesera a SGS a chipani chachitatu. Popeza tili ndi chidziwitso chambiri pa ntchito, tikumvetsa kuti ntchito iliyonse ili ndi zofunikira zapadera. Ichi ndichifukwa chake timapereka ma transformer osinthika, kulola kusintha kwa magetsi, mphamvu, njira yolumikizira, ndi kapangidwe kapadera kuti kagwirizane bwino ndi zosowa zanu. Transformer yokhazikika pa 2500 kVA ikhoza kusinthidwa kuti igwirizane ndi zofunikira za polojekiti yanu. Lumikizanani ndi Daelim Transformer lero kuti mulandire pepala la magawo, zojambula, ndi mtengo wa transformer yokhazikika pa 2500 kVA.
