2. On October 18, 1979, with the approval of the superior department, Changshu County Electric Machinery Plant was hung with two brands, namely "state-owned Changshu Wireless Power Plant" and "Changshu County Electric Machinery Plant". It belongs to two brands and one team. Changshu Electrical Machinery Factory mainly produces electrical machinery products. The ZD6 DC motor produced is a railway switch motor. The state-owned Changshu Wireless Power Plant mainly produces electronic products, and has successively produced stereo pickup heads, piezoelectric ceramic filters, sound arms, and analog-to-digital converters. Among them, stereo pickup heads were awarded the title of high-quality product by the Ministry of Electronics Industry in 1986. Therefore, it has become the only largest professional designated manufacturer of microphone heads in China.

3. In 1988, Changshu City Economic Commission and Changshu City Electronics Company approved the establishment of Changshu Jiangnan Electric Machinery Factory (formerly Changshu County Electric Machinery Factory), a state-controlled joint venture. The following year, through the first phase of technical transformation, an annual production capacity of 200000 sets of fluorine-resistant motors for refrigerator compressors was formed. The product won the Changshu Science and Technology Progress Award. In 1991, fluorine resistant motors were included in the provincial spark plan.

4. In October 2002, the original state-owned Changshu Wireless Power Plant was renamed Changshu Jiangnan Electric Machinery Manufacturing Co., Ltd., which is a limited liability company. Focus on producing refrigerator compressor motors. Specialized Supporting Electrical Appliances Co., Ltd.
