Substations - Rsafele Electric

Voltage Transformation and Power Distribution

Substations step voltage levels up or down to ensure efficient power transmission over long distances and safe distribution to end users, minimizing energy losses across the network.

Protection and Control of Electrical Equipment

Through protection relays, circuit breakers, and control systems, substations detect faults, isolate abnormal sections, and safeguard critical equipment to maintain system stability and operational safety.

Monitoring, Automation, and System Integration (SCADA)

Modern substations are equipped with monitoring and communication systems that enable real-time data acquisition, remote control, and seamless integration with SCADA platforms, improving operational efficiency and grid reliability.

We provide complete substation solutions - from concept to commissioning - to meet the growing demand for reliable, safe, and efficient power distribution.
Whether for utilities, industrial users, renewable energy plants, or infrastructure networks, we deliver turnkey systems that comply with IEC, IEEE, ANSI, CSA and regional utility standards.
Each substation type can be tailored with the required voltage levels, capacities, and configurations to meet local standards and project conditions.

Unit Substation Transformer

A unit substation transformer is a pre-assembled, compact power distribution unit that steps down medium-voltage utility power to safe, usable voltages. Its close-coupled design integrates the transformer with primary and secondary switchgear near the load, minimizing cabling and bus lengths, reducing power losses, improving voltage regulation, and enhancing service reliability.

Rated power up to 10 MVA
Rated insulation level up to 161 kV
Temperature rise: 55℃,65℃,55/65℃,45℃

Custom Features

Electrostatic shielding to reduce interference.
High-grade enclosure corrosion protection (C5-M, marine/industrial) and seismic-resistant design.
Custom bushing positions and wiring (top/side entry, special openings).
Quick-install design with fan openings, lifting points, and fast grounding terminals.
Low-noise design according to client requirements.
Special impedance, tolerance, and K-factor designs for improved harmonic and nonlinear load handling.
Supports liquid-filled, dry-type, and special transformer designs for specific applications

Compact Substation Transformer

A compact substation, also known as a prefabricated substation, is a factory-assembled, fully enclosed power distribution unit that integrates high-voltage switchgear, transformers, and low-voltage equipment into a single compact structure. Designed for efficient power transformation and distribution, it features a robust steel enclosure with multiple protections, making it suitable for both indoor and outdoor installations in residential, commercial, and industrial applications.

Transformer capacity ≤ 20000 KVA
Rated voltage: 12 - 72 kV
Enclosure protection level: IP54
Maximum altitude: 5000 meters
The background monitoring system enables real-time monitoring of critical points, including primary contact temperature, insulation partial discharge, and arc light.
Various insulation schemes are adopted, such as environmentally friendly gas insulation, air insulation, solid insulation, and semi-insulation.

Containerized Substation Transformer

A containerized substation transformer is a pre-assembled, modular power distribution unit that houses medium- and low-voltage switchgear, transformers, and auxiliary equipment within a durable steel container. Designed for rapid deployment, easy transport, and turnkey installation, it provides reliable, weather-resistant power solutions for temporary sites, outdoor installations, industrial projects, and mission-critical applications.

Up to 600000kVA 7550kV
Rated voltage: 12 - 550 kV

Lightning protection, emergency lighting, alarms, and safety accessories.
Solar PV step‑up substations with integrated inverter/DC components.
Options for grid automation, remote monitoring, and SCADA integration
Cast resin, oil‑filled, or air‑insulated transformer options based on project needs.

Vehicle-mounted mobile substation Transformer

A vehicle-mounted mobile transformer is a trailer- or chassis-mounted mobile substation that integrates a high-voltage transformer, MV/LV switchgear, protection devices, and auxiliary systems into a single unit. Designed for rapid deployment and outdoor operation, it provides flexible, reliable temporary power solutions for emergency, maintenance, and remote site applications.

Up to 240000kVA 330 kV
Rated voltage: 12 - 330 kV
Maximum rated short-term withstand current: 63 kA;
Intelligent monitoring & control - built‑in SCADA/remote monitoring systems for real‑time parameters (voltage, current, temperature) and remote control.
High environmental protection - IP55‑rated enclosures, shockproof and corrosion‑resistant options for harsh environments (high humidity, sandstorms, coastal areas).
