Company Profile
Created on 08.28
The company was founded in 1990 in Shanghai. With over ten large-scale foil winding machines and wire winding machines, it is capable of producing transformers up to 2000 KVA. The products have a maximum operating voltage of 10,000 volts and an operating current ranging from 1A to 5000A.
Our company is equipped with partial discharge testing equipment for conducting partial discharge tests. During temperature rise tests, we utilize thermal imagers and infrared technology. We also have our own silicon steel sheet cutting equipment, allowing us to process sheet metal and manufacture cabinets independently.
Our products feature a compact structure, small size, excellent electrical performance parameters, and low temperature rise. Currently, the company has obtained ISO9001 international quality assurance system certification, RoHS environmental product certification from Germany's TUV, CE product safety certification from Switzerland's SGS, and UL certification from the United States. From product development and design to manufacturing process planning and quality control, every aspect of our operations strictly adheres to ISO9001 standards. This has built customer confidence in the Dongpu brand, earning us a strong reputation in both international and domestic markets.
