Overview
In the European-style prefabricated substation the high voltage switchgear, the transformer and the low voltage switchgear are integrated into one unit, so the substation is supplied as a strong, complete set rather than as separate pieces of equipment assembled on site.
The high and low voltage protection is complete, the operation is safe and reliable, and maintenance is simple. The arrangement also occupies less land and requires less investment than a conventional substation building, with a short production cycle and convenient movement.
The enclosure uses a unique honeycomb structure double-layer composite board shell. This construction is firm and provides heat insulation, heat dissipation and ventilation, while keeping a high protection level. Several styles are available, including general type, villa type and compact type.
Key Features
- Integrated three-part assembly — the high voltage switchgear, transformer and low voltage switchgear are integrated, so the unit is supplied as a strong, complete set.
- Complete HV and LV protection — protection is provided on both the high and low voltage sides, with safe and reliable operation and simple maintenance.
- Low land occupation and investment — the compact arrangement occupies less land and requires less investment, with a short production cycle and convenient movement.
- Flexible grounding schemes — a range of grounding arrangements is available to suit the network design.
- Honeycomb double-layer shell — the composite board shell is firm and provides heat insulation, heat dissipation and ventilation, with an attractive finish and a high protection level.
- Wide choice of shell materials — stainless steel alloy, aluminium alloy, cold-rolled plate, colour steel plate, tiled and wood strip finishes and new environmentally friendly materials are available, with surface watercolour painting.
- Multiple styles — general type, villa type and compact type styles are offered.
- Distribution automation ready — distribution automation terminals (FTU) can be assembled in the high voltage ring network cabinet for reliable detection of short-circuit and single-phase grounding faults.

Applications
- Urban power grid renovation — distribution substations for city network upgrading projects.
- Residential quarters and high-rise buildings — power distribution serving housing developments.
- Industrial and mining facilities — distribution for industrial and mining sites.
- Hotels, shopping malls and airports — distribution for commercial and transport facilities.
- Railways, oil fields, docks and highways — distribution for infrastructure along transport and energy corridors.
- Temporary power-consuming facilities — both indoor and outdoor temporary supply arrangements.
Installation Conditions
- The substation can be installed indoors or outdoors, and is suitable for both permanent and temporary power-consuming facilities.
- Because the shell provides heat insulation and ventilation, the unit suits a range of outdoor conditions without additional cooling.
- Where distribution automation is required, the FTU is assembled in the high voltage ring network cabinet.
- The shell material should be selected according to the site environment and the desired appearance, from stainless steel alloy through to tiled and wood strip finishes.
How to Select
- Style required — general type, villa type or compact type.
- Shell material and surface finish, including whether a watercolour finish is wanted.
- Shell protection level required for the installation environment.
- Voltage level and transformer capacity required by the load.
- High voltage ring network cabinet configuration, including the number of ways.
- Whether a distribution automation terminal (FTU) with short-circuit and single-phase grounding fault detection is required.
- Grounding scheme required for the network design.
FAQ
What is integrated into a European-style prefabricated substation?
The high voltage switchgear, the transformer and the low voltage switchgear are integrated into a single unit. The set is therefore supplied complete and strong, which shortens the production cycle and reduces on-site assembly work.
What is the honeycomb double-layer shell?
It is a double-layer composite board shell with a honeycomb structure. The construction is firm and provides heat insulation, heat dissipation and ventilation, while keeping an attractive appearance and a high protection level.
Which shell materials and finishes are available?
Stainless steel alloy, aluminium alloy, cold-rolled plate, colour steel plate, tiled and wood strip finishes and new environmentally friendly materials are all available, and surface watercolour painting can be applied.
Which styles of substation are offered?
General type, villa type and compact type styles are available, so the appearance can be matched to the surrounding environment.
What does the distribution automation terminal (FTU) provide?
An FTU can be assembled in the high voltage ring network cabinet to provide reliable detection of short-circuit and single-phase grounding faults. It also provides the four-remote functions, which makes distribution automation upgrades straightforward.
Where can this substation be installed?
It is widely used in urban power grid renovation, residential quarters, high-rise buildings, industrial and mining sites, hotels, shopping malls, airports, railways, oil fields, docks, highways and temporary power-consuming facilities, both indoors and outdoors.
