High Voltage Resisitive Load Bank by Rata-2

Product Overview

- 5 MW / 11 kV AC resistive load bank (model RT5000kWLB) in a containerized outdoor design.

- Dimensions 12000 × 2530 × 2600 mm, weight ~18,000 kg, mounted on a cement base with lift lugs for handling.

- Continuous-duty, high-voltage load unit used for large-scale power-system testing (example: Rwanda National Gas Power Plant).

Product Features

- High-voltage design for 11 kV (custom voltages available); rated power 5000 kW.

- Control: local panel switching and remote PC/PLC operation via Modbus TCP; data logging and printout supported.

- Load resolution and steps: 100 kW resolution with configurable step groups (total combination up to 5 MW).

- Resistive elements: 8020 Ni-Cr alloy finned resistors; tin-plated copper bus connections.

- Cooling/enclosure: forced-air cooling with horizontal intake and vertical outlet air ducts (weatherproof and animal-proof); Q235 steel, powder-coated enclosure.

- Performance: loading accuracy ≤ 3%, 3-phase unbalance ≤ 3%, insulation class F, frequency 50/60 Hz, noise < 80 dB at 3 m.

- Protections: over-temperature, low airflow, phase-sequence, short-circuit, fan interlock, access control, emergency stop, temperature & humidity monitoring.

- Expandable: supports parallel expansion of multiple load units.

Product Value

- Enables safe, accurate full-load testing and commissioning of high-voltage generators, switchgear and power systems, reducing commissioning risk and unplanned downtime.

- Remote monitoring and data logging support traceable acceptance testing and easier reporting.

- Rugged, weatherproof design allows outdoor installation close to test sites, saving installation time and infrastructure cost.

- Modular step control and parallel expansion provide flexible, scalable testing for different equipment sizes and future needs.

- Manufacturer support (24/7 service, commissioning and training available) helps ensure reliable deployment and operator competence.

Product Advantages

- Built with precision manufacturing and quality materials (Ni‑Cr resistors, Q235 steel, tin‑plated copper bus) to meet international, ship, military and telecom standards.

- High accuracy and good 3-phase balance for representative load behavior.

- Robust protection systems and continuous-duty capability for safe long-duration tests.

- Weatherproof containerized layout with air ducts prevents water ingress and animal intrusion—suitable for outdoor installation.

- Proven supplier experience and on-site service options including commissioning and operator training.

Application Scenarios

- Power plant testing and commissioning (gas, thermal, hydro) and routine generator load testing.

- Grid and substation acceptance tests, transformer and switchgear verification.

- Large industrial and utility sites requiring high-power load simulation for maintenance and diagnostics.

- Telecom, military, and shipboard test applications (meets corresponding standards).

- Factory acceptance tests, on-site commissioning, emergency backup generator validation and training exercises.
