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

📘 Introduction to 1000 kVACompactSubstation Size

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.

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

У "The1000 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

🗺️ 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:

Aflat concrete plinth200–300 mm above ground
Clearance of 1.2–1.5 metersaround doors for maintenance
Cable trenches beneath or beside the unit
Space forventilationand 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

Usemodular designto save space in urban zones
Opt fordry-typetransformersfor indoor or fire-sensitive areas
Selectside-entry cable routingto reduce trench requirements
Confirmtransport size restrictionsfor delivery access
Allow forfuture expansion spaceif growth is expected

❓ Frequently Asked Questions (FAQs)

Q1: Can a 1000 kVA compact substation fit in a 5×3 meter area?

A:Yes, standard metal enclosures with inline layout can be installed in such space, with minor clearance adjustments.

Q2: Is it possible to install this substation indoors?

A:Yes, especially with dry-type transformers and adequate ventilation. PINEELE offers indoor-rated enclosures.

Q3: What is the weight of a fully assembled 1000 kVA substation?

A:Approximately 4.5 to 6 tons, depending on transformer type and materials used.
