Wopereka Chitetezo cha Zachilengedwe Padziko Lonse

Dongfang imapereka filimu ya polypropylene yolunjika mbali ziwiri yokhala ndi njira yolumikizirana. Popeza ndife opanga oyamba opanga filimu ya polypropylene yogwiritsira ntchito capacitor yamagetsi, tikutsogolera msika pogwiritsa ntchito ukadaulo ndi njira zodziyimira tokha, zomwe zidapangidwa kudzera mu zaka zoposa 30 zaukadaulo wopanga komanso kuyambitsa ndi kuyamwa kwaukadaulo wambiri. Chifukwa cha magwiridwe antchito abwino kwambiri a winding, immersion yamafuta ndi kukana magetsi, yakhala njira yoyamba yamapulojekiti akuluakulu a grid aku China, kuphatikiza Ultra High Voltage Direct Current Power Transmission System.
