Description
With the continuous increase in the requirements for the rapidity and flexibility of power supply construction in China, the construction mode is gradually evolving from the traditional decentralized power grid infrastructure construction mode to the overall "turnkey project" approach.
Facing the new situation and challenges, the company realizes the rapid production of prefabricated cabins with the new concepts of standardized design, factory prefabrication, and modular construction. This reduces the on - site construction and commissioning work, shortens the construction period, has strong environmental adaptability, and saves the floor area, building area, and investment scale.
The prefabricated cabin is mainly composed of the cabin body, the primary and secondary combined equipment inside the cabin, the cabin auxiliary facilities, as well as relevant power distribution cabinets, equipment screens, etc. (the equipment varies according to different designs). It has good wind resistance, earthquake resistance, and snow load resistance to ensure the safe operation of the equipment. At the same time, according to the actual usage requirements, necessary auxiliary equipment such as lighting, HVAC, and fire - fighting equipment can be installed. These are assembled in the factory and transported to the site for hoisting.
Product Introduction
The main body of the steel structure is welded and formed, with high-strength earthquake resistance and an earthquake resistance performance of magnitude 8.
It has multi-layer protection, is safe and reliable, with an overall protection level of IP54 and a service life of at least 40 years.
It features standardized design, modular optional schemes, and a short production cycle.
It has functions of heat preservation, dust prevention, moisture prevention, condensation prevention, and sound insulation. It is equipped with a temperature and humidity control system and a ventilation system, and has a complete monitoring, security, and fire alarm system, with excellent fire resistance performance.
It has multiple anti-corrosion processes such as sandblasting, zinc spraying, and anti-corrosion paint, and can adapt to a long-term salt spray environment.
The work grounding, protection grounding, lightning protection grounding, and anti-static grounding are completed inside the cabin.
The primary and secondary cables inside the cabin are laid in dedicated cable channels, which are independent and airtight.

Product Features
Factory - pre - installed, safe and reliable: Through standard design, factory pre - fabrication, pre - installation and pre - adjustment, the quality process can be highly controlled. The equipment adopts pre - fabricated cabin - type buildings to improve seismic performance. Reducing the building height of the structure and the overall height of the station can decrease the probability of lightning strikes.
Intelligent technology for convenient operation and maintenance: The application of intelligent technology and advanced auxiliary systems can monitor the operation status of the substation and equipment in real - time, enabling unmanned operation and planned maintenance.
Integrated design for land - saving: With modular design, high integration, and a compact layout structure, the overall plane layout of the substation is optimized, resulting in a small footprint.
Prefabricated construction for shorter cycle: Reducing the process of concrete construction shortens the construction cycle and improves construction efficiency.
