Rata High Voltage Resisitive Load Bank High Voltage Resisitive Load Bank Factory
Product Overview
- Rata RT5000kWLB is a 5 MW (5000 kW) high-voltage resistive load bank, factory-designed as a container-type outdoor unit for AC 11 kV systems (other voltages customizable).
- Key physical data: 12000 × 2530 × 2600 mm, ~18,000 kg, continuous-duty operation, designed for outdoor installation on a concrete base and supplied wrapped in film for export.
Product Features
- High-voltage design using 11 kV contactors, connected with tin-plated copper busbar; control power AC 380 V, 3-phase, 4-wire.
- Loading accuracy ≤ 3% and 3-phase unbalance ≤ 3%; frequency 50/60 Hz; continuous duty.
- Fine load-step resolution (100 kW increments) with a defined step set (100 + 200 + 200 + 500 + 1000 + 1000 + 1000 + 1000 kW) and support for parallel expansion of multiple units.
- Cooling and enclosure: forced-air cooling with horizontal intake and vertical outlet via air ducts (waterproof and animal-proof), axial fans (noise < 80 dB at 3 m), Q235 steel powder-coated enclosure, lift lugs for movement.
- Resistors: 8020 Ni-Cr alloy finned elements. Digital metering of voltage, current, power, power factor and frequency. Remote (Modbus TCP / PLC) and local control modes, with data save/print capability.
- Protections: high temperature, low air volume, phase sequence, short circuit, fan interlock, access control, temperature & humidity control, emergency stop. Meets international, ship, military and telecommunication standards.
Product Value
- Provides a reliable, high-capacity means to commission, test and exercise high-voltage generators, power plants, UPS and distribution systems under realistic resistive loads.
- Improves system reliability and availability by validating equipment performance, revealing faults before service, and enabling planned maintenance without taking critical systems offline.
- Offers configurable, accurate, and recorded load profiles (local or remote operation) to support commissioning, acceptance testing and long-term asset verification.
- Rugged outdoor design (waterproof/animal-proof) and international standards compliance reduce installation constraints and lifecycle risk in harsh environments.
Product Advantages
- Factory-engineered original design with strict testing to international standards, delivering high performance and long service life.
- Flexible operation: local panel switching or full remote PC/PLC control with logging and printing. Easy expansion by paralleling units.
- Robust safety and reliability features (comprehensive protection suite, Q235 enclosure, altitude/humidity operating specs).
- After-sales support: 24/7 service, on-site commissioning and paid training to ensure correct operation and handover.
- Proven export experience and company capabilities—manufacturing expertise, logistics advantage and a track record in international markets.
Application Scenarios
- Power station and plant commissioning and maintenance (example: used at a national gas power plant).
- High-voltage generator and prime mover testing, routine load bank exercises for standby/backup units.
- Grid simulation and load-transfer testing for utilities, industrial sites, and large commercial facilities.
- Telecom and military facilities requiring certified high-voltage load testing.
- Factory acceptance testing, R&D labs, and any large-scale electrical system needing controlled, accurate resistive loading.
