Overview
У "The Компактна підстанція 11кВ represents a highly efficient and modular solution for medium-voltage to low-voltage distribution systems. Designed for rapid deployment and minimal spatial footprint, this integrated unit brings together a transformer, medium-voltage switchgear, and low-voltage panel, all housed within a weatherproof and tamper-resistant enclosure.
Widely used in urban developments, industrial zones, and utility distribution networks, 11kV compact підстанції have become a standard in modern electrical infrastructure.
Why Choose an 11kV Compact Substation?
- Ideal for space-constrained environments
- Pre-tested and factory-assembled for rapid installation
- Reduces site work and civil infrastructure requirements
- Enhances safety through isolated compartments and arc protection
- Fully compliant with IEC, ANSI, and utility-specific standards

Component Breakdown
1. Medium Voltage Section
This compartment houses 11kV switchgear, which may include load break switches (LBS), vacuum circuit breakers (VCBs), or SF6-insulated ring main units (RMUs). Surge arresters and fault indicators ensure system protection and real-time diagnostics.
2. Transformer Chamber
The core of the substation, this segment contains a sealed, oil-immersed or dry-type transformer. Heat sensors, pressure relief valves, and oil level indicators are standard inclusions for safety and efficiency.
3. Low Voltage Section
Outgoing feeders, equipped with MCCBs or ACBs, allow for seamless connection to distribution panels. Metering instruments and protection relays offer full operational visibility and control.
Enclosure & Structure
- Modular, compartmentalized layout with isolated access
- Galvanized steel or stainless-steel enclosure with anti-corrosive treatment
- Cable entry: bottom or side, as per project layout
- Cooling: natural ventilation or forced air (optional)
- Earthing system: integrated copper ground bars and pits
- Tamper-proof and suitable for remote installations
Compliance & Standards
This product adheres to multiple global and regional standards:
- IEC 60076 – Power transformers
- IEC 62271-202 – Prefabricated substation enclosures
- IEC 61439 – Low-voltage switchgear assemblies
- ISO 9001 / 14001 – Quality and environmental management
- Custom configurations per utility (e.g., TNB, Eskom, DEWA)
