Zvemagetsi zvakapfava zvinoumba zvinhu zvinosanganisira E, B, F, uye H mamakisi ane simba remuchina.Dielectric zvivakwa uye yakavimbika thermal adhesion.Iyo E giredhi inosanganisira pepa rinoumbwa;giredhi B rinosanganisira DMD, DMDM, DM;giredhi reF rinosanganisira F giredhi DMD;H giredhi rinosanganisira NHN neNMN.Inoshandiswa zvakanyanya mumidziyo yekugadzira magetsi senge slot insulation, kutendeuka-ku-turn insulation uye gasket insulation yemagetsi emagetsi, kufambisa magetsi uye shanduko yemidziyo, traction locomo tives, mota, midziyo yemagetsi nemagetsi.
