Mechanical and electrical installation engineering usually includes electrical, ventilation, plumbing, and equipment installation work.
Most of today's enterprises have automated machinery and equipment, which gave birth to the electromechanical installation industry. Installation of equipment, lines, and pipelines for general industrial, public, and civil construction projects, construction of 35 kV and below substations, and production and installation of non-standard steel components. Mechanical and electrical installation is a relatively large-scale project, and some large enterprises may relocate. It takes nearly six months to implement a project, and the technical requirements for installation are also quite high. The engineering content includes boilers, ventilation and air conditioning, refrigeration, electrical, instrumentation, motors, compressor units, and equipment such as broadcasting, film, and television control.
