Global Procurement Guide for Containerized Substation
Containerized Substation overview
-The main function of prefabricated compartment substation (container type substation) is to convert the low-voltage AC generated by the power generation system in the field of new energy into medium voltage AC, and feed the electric energy into the national power grid.
-It is applicable to the construction and transformation of 10 ~ 110kV small and medium-sized substations (distribution) in petroleum, chemical industry, drilling platforms, urban and rural areas, factories, mines and mobile operation substations.
-Prefabricated compartment substation integrates low-voltage cabinet, transformer, ring main cabinet, auxiliary power supply and other equipment into a steel structure container to provide a highly integrated power transformation and distribution solution for medium voltage grid connection of ground power station.
Containerized Substation advantage
>Leading technology
-Fully enclosed, fully insulated structure, easy operation, maintenance free, safe and reliable operation
-The equipment can be moved, the hoisting is convenient and the cost is low
>Shell
-The box shell has the characteristics of firm, heat insulation and ventilation, stable performance (anti-corrosion, dust-proof and waterproof), beautiful appearance and so on
-There are many choices of shell materials, such as cold-rolled steel plate, hot-dip steel plate, 304 stainless steel, etc. the protection grade of the shell is IP54
-The outer wall of steel plate is anti-corrosion, electrostatic spraying, corrosion resistance, acid resistance, high weather resistance, and the service life is more than 30 years
>Functional unit
-It has the functions of energy control, DCS control, remote communication and so on.

Containerized Substation FAQ
1. What is a Containerized Substation?
A Containerized Substation is a compact, pre-assembled electrical substation housed in a standardized shipping container. It includes power transformers, switchgear, protection devices, and control systems, designed for quick deployment and mobility.
2. What are the main advantages of Containerized Substations?
Faster deployment (reduced on-site construction time)
Cost-effective (lower installation and labor costs)
Modular & scalable (easy to expand or relocate)
Weather-resistant & secure (robust container protection)
3. Where are Containerized Substations typically used?
Remote areas (mining, oil & gas, renewable energy sites)
Emergency power restoration (disaster recovery, temporary power)
Urban grids (space-constrained locations)
Military & mobile applications
4. How long does it take to install a Containerized Substation?
Installation can take weeks instead of months since most components are pre-tested and factory-assembled. On-site work mainly involves connection and commissioning.
5. Are Containerized Substations customizable?
Yes, they can be tailored for voltage levels (e.g., 11kV, 33kV, 66kV), capacity, and specific requirements like SCADA integration, GIS (Gas-Insulated Switchgear), or hybrid power systems.
6. What safety features do Containerized Substations have?
Fire-resistant materials
Ventilation & cooling systems
Surge & lightning protection
Secure locking & tamper-proof designs
7. How do Containerized Substations handle extreme weather?
Containers are built to withstand harsh conditions (e.g., -40°C to +50°C) with features like:
HVAC systems for temperature control
Corrosion-resistant coatings
Waterproof & dustproof enclosures (IP54/IP65 ratings)
8. Can renewable energy sources integrate with Containerized Substations?
Yes, they can connect to solar, wind, or battery storage systems, making them ideal for microgrids and hybrid power solutions.
9. What maintenance is required for Containerized Substations?
Regular inspections of electrical components
Cooling system checks
Software updates for control systems
Minimal maintenance due to sealed and protected designs
