What are the main electrical materials commonly used

In the chemical plant commonly used PVC protective casing, galvanized steel pipe, grounding electrode, grounding wire (various specifications), power cables, channel boxes, jumper cables and so on. It is the great progress of electronic technology is to promote the computer network based on the arrival of the information age, and change all aspects including human life and work mode. The electrical engineering discipline of American University, also known as the Department of Electrical Engineering, the Department of Electrical Engineering and Information Science, the Department of Electrical Engineering and Computer Science, etc., the main direction and focus of research on computers and information technology.

Electrical:

Electrical Engineering (abbreviation:EE), is a core and key discipline in the field of modern technology. Traditionally, electrical engineering has been defined as the sum of the related disciplines used to create the electrical and electronic systems that produce them. This definition was originally very broad, but with the rapid development of science and technology, the concept of electrical engineering has gone far beyond the scope of the above definition. Stanford University professor pointed out: "Today's electrical engineering covers almost all of the engineering behavior related to electrons and photons".
