E-house, also known as modular distribution intelligent box type substation, prefabricated electrical equipment room, skid mounted room, modular equipment room, prefabricated cabin combination equipment, etc., has transformed engineering construction into a complete process of factory production, combining various links such as design, production process, construction methods, and organizational management to establish a complete construction system.After the equipment required for the substation is systematically integrated and debugged in the factory, it can be transported to the site and put into use. This construction system enables design standardization, factory building production, construction mechanization, and project organization and management. Currently, it is widely used in power generation, mining, chemical industry, crude oil and natural gas, transportation, production lines, industrial plants, offshore platforms, and other places.

Advantages
　　Compared with traditional power plants, E-house has a large workload in civil engineering, a large workload in on-site installation and debugging of internal equipment, and a high cost.The internal main power distribution equipment, heating, cooling, ventilation, lighting, fire alarm, monitoring and other supporting equipment of E-house are assembled and debugged in the factory, greatly shortening the on-site construction cycle and saving a lot of manpower and material resources. At the same time, it has many advantages such as low radiation, low cost, small floor area, short production cycle, and small on-site construction volume.

Features
• Composite structure cabin, resistant to mechanical shock, thermal insulation.
• The main components and supporting products are all made of internationally and domestically advanced products, with excellent performance, safety and reliability.
• Factory production and debugging.
• Split transportation and on-site consolidation.
• Prefabricated optical cables, prefabricated cables, and other "plug and play" standardized connections are used on site, allowing for quick connection of optical cables and cables between primary and secondary equipment, reducing on-site construction safety risks.
• Intelligent control, achieving unmanned operation.
