Generally speaking, their products are in the middle and low level in the whole industry, and the quality can only be said to be passable.
It can only be said that Zheng Tai is the market leader of low-voltage electrical appliances at present, but the quality is not good.
The bosses of high-voltage electrical appliances are xd Group (central enterprises) and "old five enterprises" and other enterprises.
1. As far as low-voltage circuit breakers are concerned, the best domestic enterprises should be Changshu Kai Guanchang, Shanghai People's Electric Appliance Factory, Hangzhou Zhijiang, Zunyi Changzheng, Tianshui 2 13, Shanghai Liangxin and TCL International Electrician. Others such as Jiangsu Daquan Fan Kai, Zhejiang Jiakong, Xiamen Lianrong Electric Control and Beijing Zhengbeiyuan Electric Appliance are all high-quality enterprises.
2. AC contactor: Tianshui 2 13 and Shanghai People's Electric Appliance Factory are the best in China, and the joint venture brand is Changshu Fuji Electric. The above circuit breaker manufacturers basically produce AC contactors.
3. Medium voltage circuit breakers: Changzhou Eton Senyuan (actually foreign capital), Cooper Nike (also joint venture), Beijing Huadong Senyuan, etc. Many medium voltage complete sets manufacturers produce circuit breakers.
4. Medium-voltage complete sets of equipment: Kai Guanchang and Tianshui Great Wall are the strongest in China, while others such as Hunan Switch Group, Jinkai Electric Group, Guangzhou Baiyun, Zheng Tai, Ningbo Naiji, Ningbo Tianan, Ningbo Huatong and Hangzhou Jiangdu are big manufacturers.
5. Medium-voltage transformer: The mainstream domestic manufacturers include Dayi Huzhu, Zhongshan Taifeng and Hengyang North.
6. High-voltage and ultra-high-voltage electrical appliances: brands include Kathy Electric, Xidian Switch, Gao Ping Group, Taikai Group, New Northeast Electric Shenyang High-voltage Switch, etc. Zheng Tai also produces them.
7. Relay protection devices: Xu Ji, Aji, Shangji, Beijing Sifang relay protection, Guodian Nanzi, Guodian Nanrui, Beijing Dewei, etc.
The topic of electrical industry is very big, and a few words can't be finished, hehe.
