A1000 kVA compact substationis a prefabricated, fully integrated solution thatcombines high-voltage switchgear, transformer, and low-voltage switchgear into one enclosure. One of the most critical aspects of planning for such a substation is understanding itsphysical size, footprint, layout, and space requirements.
In this guide, we provide a detailed overview of the dimensions of a 1000 kVACompact guidesubstation, layout variations, installation clearance standards, and planning considerations. All data is aligned with international best practices and PINEELE’s engineering expertise.
A typical 1000 kVA compact substation has the following overall dimensions:
| Section | Length (mm) | Width (mm) | Height (mm) |
|---|---|---|---|
| HV Compartment | 1200–1600 | 1200 | 2200–2500 |
| Transformer Comp. | 2200–2800 | 1500–1800 | 2000–2300 |
| LV Compartment | 1200–1600 | 1200–1400 | 2000–2300 |
| Total Size | 4500–6000 | 1800–2200 | 2200–2500 |
Note: Actual sizes vary based on transformer cooling type (oil/dry), protection devices, access doors, and enclosure design.
The outer enclosure or housing of the compact substation plays a key role in determining the total size:
إن1000 kVA transformeris the heaviest and largest internal component. Its size impacts the transformer compartment:
| Transformer Type | Length x Width x Height (mm) | Weight (Approx.) |
| Oil-Immersed | 2200 x 1500 x 1800 | 2000–2500 kg |
| Dry-Type Cast Resin | 1800 x 1300 x 1700 | 1800–2200 kg |
There are three common layout configurations for a 1000 kVA compact substation:
HV → Transformer → LV in a straight line (popular, narrow footprint)
Transformer in the corner, HV and LV on perpendicular sides (space optimization)
HV and LV panels on each end, transformer in center (ideal for 3-door access)
While the compact substation is pre-fabricated, it still requires:
Typical site area needed:8 to 12 square meters(minimum)
To comply with IEC/IEEE/GB safety regulations:
| Area | Minimum Clearance |
| Front of Access Doors | 1500 mm |
| Rear and Side Panels | 1000 mm |
| HV Incoming Cable Termination | 1200 mm |
| Air Flow / Ventilation Zone | 1000 mm |

A:Yes, standard metal enclosures with inline layout can be installed in such space, with minor clearance adjustments.
A:Yes, especially with dry-type transformers and adequate ventilation. PINEELE offers indoor-rated enclosures.
A:Approximately 4.5 to 6 tons, depending on transformer type and materials used.
Understanding thephysical size and layout of a 1000 kVA compact substationis essential for site planning, installation, and long-term maintenance. PINEELE provides highly optimized, space-efficient, and standards-compliant solutions to meet a wide range of application needs.
