After 2010, chemical reagents developed by national technical reform and research according to the United states of America were produced, and the chemical reagents are low in cost and are rapidly widely used in Guangzhou and Fujian areas. But the chemical reagent has the defects that the chemical components used are low in technological content due to low cost, and only the basic insulation grade can be achieved, so that the requirement of equipment with the voltage grade of 35kv or above is not met. And because the low-price chemical raw materials have corrosiveness, after electronic components are cleaned for a long time, the phenomena of corroding parts such as rubber and electronic boards are caused, and the requirements of people on buildings are not met.
