Description
Mobile Skid-Mounted Prefabricated Substation Product Overview
Prefabricated substation is more flexible and convenient to use than civil - constructed substation. They are widely applied in urban power grid reconstruction, high - rise buildings, residential communities, industrial parks, commercial centers, airports, railway stations, docks, schools, mining enterprises and other places.
Prefabricated substation (hereinafter referred to as box substation) is composed of three parts: high - voltage switchgear, transformers, and low - voltage switchgear. The overall layout is divided into combined type and integrated type (commonly known as European - style substation). In the combined type, these three parts are arranged in separate compartments. In the integrated type, the transformer serves as the main body, with high - voltage load switches, fuses, etc. installed inside the transformer casing, forming an integrated layout. 
Mobile Skid-Mounted Prefabricated Substation Product Introduction
Overall Structure
  • The product is mainly divided into three parts: the high - voltage switch room, the transformer room, and the low - voltage switch room. These three parts can be transported separately.
  • The product adopts a unique large - cycle heat dissipation design to ensure the product's temperature rise level. Each room is sealed independently, preventing heat exchange between the rooms.
  • The product's outer shell is made of high - quality steel plates. All components of the steel plate structure have undergone special anti - corrosion treatments. The stainless steel plate structure has extremely strong corrosion resistance and good mechanical strength.
  • The product can be directly installed indoors without the need for an additional building foundation, saving costs and space, and is convenient to install.

High - voltage Room

  • The high - voltage part adopts the SF6 gas - insulated switchgear independently developed by our company. All switchgears, busbars, etc. are sealed in a closed stainless - steel box, with no exposed live parts outside. It features safe operation and high reliability.
  • With a fully modular design, all modules can achieve side - outlet and top - expansion connection methods according to power consumption requirements, maximizing the satisfaction of power supply schemes.

Low - voltage Room

  • New - type plastic - case circuit breakers are used for both the incoming and outgoing lines on the low - voltage side. The switches are small in size, have no arc flash, and are easy to replace. There are also multi - function intelligent integrated protection controllers and new - type integrated reactive power compensation devices.

Transformer Room

  • The transformer is an epoxy resin fully - insulated transformer with an insulation heat - resistance class of F. The transformer has no combustible materials and does not produce any environmentally harmful gases or other intermediate products during operation. It has good flame - retardant, environmentally friendly, and energy - saving characteristics.

Internal Connection

  • The transformer and the medium - voltage solid - state switches are connected by the solid - insulation cable accessories of our company, which are safe, reliable, and fully insulated.

FAQ
Q: What scenarios are suitable for the customized mobile skid-mounted prefabricated substation?
A:

Our substation is ideal for temporary power supply projects such as construction sites and emergency repair, remote areas lacking fixed power infrastructure, and mobile power demand scenarios like outdoor events and mining operations. The 12kV, 24kV, and 34.5kV voltage grades can be flexibly matched to meet the power distribution needs of different industrial and commercial projects.

Q: What are the key advantages of your mobile skid-mounted prefabricated substation?
A:

Our customized mobile skid-mounted prefabricated substation offer three core benefits: rapid deployment (pre-assembled design eliminates on-site complex installation), flexible mobility (skid-mounted structure enables easy relocation for temporary projects or remote areas), and voltage versatility. They are engineered for high reliability and low maintenance, ideal for industrial, utility, and emergency power scenarios.

Q: What advantages does the mobile skid-mounted prefabricated substation have in installation and layout?

A: It can be directly installed indoors without additional building foundations, saving costs and space with convenient installation. Its skid-mounted design enables easy movement and transportation, and the three core parts support separate transportation for flexible deployment.

Q: How does the mobile skid-mounted prefabricated substation ensure heat dissipation and operational stability?

A: It adopts a unique large-cycle heat dissipation design to control temperature rise. Each compartment is independently sealed to avoid heat exchange between rooms, ensuring stable operation even in continuous working conditions.

Q: What application scenarios are suitable for mobile skid-mounted prefabricated substation?

A: They are widely used in urban power grid reconstruction, high-rise buildings, residential communities, industrial parks, commercial centers, airports, railway stations, docks, schools, mining enterprises, and other places requiring flexible and convenient power supply.
