1000 kVA Compact Substation Size: Dimensions, Layout, and Space Requirements

📘 Introduction to 1000 kVA Compact Substation Size

A 1000 kVA compact substation is a prefabricated, fully integrated solution that combines 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 its physical size, footprint, layout, and space requirements.

In this guide, we provide a detailed overview of the dimensions of a 1000 kVA Compact guide substation, layout variations, installation clearance standards, and planning considerations. All data is aligned with international best practices and PINEELE’s engineering expertise.

Standard Dimensions of 1000 kVA Compact Substation

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.

Enclosure Options and Impact on Size

The outer enclosure or housing of the compact substation plays a key role in determining the total size:

1. Metal Sheet Enclosure (Mild Steel/GI Painted)

Compact and cost-effective
Suitable for moderate environments
Approximate size: 4.5m x 2.0m x 2.3m

2. Stainless Steel or Galvanized Housing

Designed for harsh or coastal environments
Anti-corrosion
Slightly thicker walls increase footprint

3. Concrete Housing (Prefabricated Kiosk)

Best for vandal-prone or fire-sensitive areas
Bulkier and heavier
Approximate size: 6.0m x 2.2m x 2.5m

Dimensions, Layout, and Space Requirements

📏 Transformer Size Within the Substation

A 1000 kVA transformer is 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

🗺️ Layout Configurations

There are three common layout configurations for a 1000 kVA compact substation:

🔹 Inline Layout

HV → Transformer → LV in a straight line (popular, narrow footprint)

🔹 L-Shape Layout

Transformer in the corner, HV and LV on perpendicular sides (space optimization)

🔹 U-Shape Layout

HV and LV panels on each end, transformer in center (ideal for 3-door access)

📦 Foundation and Installation Space Requirements

While the compact substation is pre-fabricated, it still requires:

A flat concrete plinth 200–300 mm above ground
Clearance of 1.2–1.5 meters around doors for maintenance
Cable trenches beneath or beside the unit
Space for ventilation and oil containment (for oil-immersed units)

Typical site area needed: 8 to 12 square meters (minimum)

🔐 Clearance Standards & Safety Zones

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

Design Tips from PINEELE

Use moduláris felépítés to save space in urban zones
Opt for dry-type transformers for indoor or fire-sensitive areas
Select side-entry cable routing to reduce trench requirements
Confirm transport size restrictions for delivery access
Allow for future expansion space if growth is expected

Application Areas Where Size Matters

City centers and urban infrastructure
Underground or rooftop substations
Renewable energy systems (solar/wind)
Industrial parks with space limitations
Temporary or mobile power setups
