Depending on the demand, many low-end brands can be replaced. Most of the high-end ABB and Siemens products can also be replaced, and many manufacturers already have customized services for the use environment. For example, textile scenes have a lot of fluff, mining scenes have a lot of dust, chemical scenes have many corrosion problems, etc. Many domestic manufacturers can now meet the customization requirements.

There are many domestic manufacturers, such as Inovance, Ao Zhuo, INVT, Senlan, Lanhai Huateng, Niye, Senlan, Fengguang, New Era, etc. Some of these manufacturers provide specially customized products. Services or accessories are imported. Compared with purely domestic manufacturers, imported accessories manufacturers meet the quality requirements at low prices and are the most potential substitutes for foreign brands.
