Rata High Voltage Resisitive Load Bank Factory

Product Overview

1) Product overview

Product Features

- The Rata High Voltage Resistive Load Bank (model RT5000kWLB) is a 5 MW, 11 kV AC, container‑type resistive load bank manufactured by Deyang Rata Technology Co., LTD.

Product Value

- Built for outdoor use with horizontal air intake and vertical ducted exhaust, the unit is weather- and animal‑protected and sized at 12,000 × 2,530 × 2,600 mm (L×W×H), weighing about 18,000 kg.

Product Advantages

- Designed for continuous duty operation, it is suitable for high‑voltage power system testing and commissioning.

Application Scenarios

2) Product features

- Electrical: 5000 kW rated power at 11 kV (custom voltages available), 50/60 Hz, control power AC 380 V 3‑phase 4‑wire. Insulation class F.

- Loading & control: Loading accuracy ≤ 3%, 3‑phase unbalance ≤ 3%, fine resolution 100 kW steps with modular step grouping, local panel switching or remote PC control via Modbus TCP/PLC with data save/print.

- Construction & cooling: 8020 Ni‑Cr finned resistors, forced‑air axial fans, noise < 80 dB at 3 m, Q235 steel powder‑coated enclosure (RAL7035), lift lugs for movement.

- Protection & instrumentation: Built‑in protections (high temp, low air volume, phase sequence, short circuit, fan interlock, access control, temp/humidity control, emergency stop) and digital meters for V, I, P, PF and frequency.

- Expandability & standards: Supports parallel expansion of multiple units and complies with ship, military and telecommunication standards.

3) Product value

- Enables safe, accurate, and repeatable high‑voltage load testing and commissioning of generators, transformers and distribution systems without relying on live customer loads.

- Reduces commissioning time and operational risk by providing controlled, continuous resistive loading with detailed data logging and remote control.

- Robust outdoor design and waterproofing simplify site logistics (single film packing for export) and reduce installation preparation.

- Manufacturer support (24/7 after‑sales, commissioning and operator training) helps ensure reliable deployment and faster ramp‑up.

4) Product advantages

- High voltage capability (11 kV) with high total power (5 MW) in a containerized, transportable package tailored for power station use.

- Precise loading (≤3% accuracy) and balanced 3‑phase performance reduce test uncertainty.

- Modular step design and parallel expansion allow flexible configuration to match a wide range of test profiles.

- Comprehensive protections and industrial‑grade construction (Q235 steel, powder coat) provide durability in harsh field conditions and compliance with multiple standards.

- Remote operation (Modbus TCP/PLC/software) and data recording support modern commissioning and diagnostic workflows.

5) application scenarios

- Utility and independent power plant commissioning and performance verification (e.g., gas and thermal power plants).

- Generator and transformer acceptance testing, load bank testing for commissioning and preventive maintenance.

- Substation and switchgear testing, relay and protection system validation.

- Military, maritime and telecommunication critical power system testing (compliant with corresponding standards).

- Factory acceptance tests, contractor site testing, and any industrial facility needing high‑voltage resistive load simulation.
