As we all know, CBSC has been a factory for 30 years, and many electrical cabinets and cables in the infrastructure have been used for more than 20 years. Some old cables and components are aging, and they do not meet the standards and safety requirements of electrical cabinets. These need to be replaced. Since 2016, we have identified 221 electrical cabinets that need to be replaced. At present, we have only completed 46. We need to speed up the replacement process to ensure the stability of the infrastructure.
