Resistive Load Bank High Voltage Resisitive Load Bank From China

Product Overview

- 5,000 kW (R5MW) high-voltage resistive load bank designed and manufactured by Deyang Rata Technology Co., Ltd for outdoor use (container type) and primarily aimed at gas‑fired power plant and generator test applications.

- Rated for AC 11 kV (other voltages customizable), continuous duty, with full local panel and remote PC control options (Modbus TCP / PLC).

- Compact container dimensions (12,000 × 2,530 × 2,600 mm), weight ~18,000 kg; designed for operation from –20 °C to 50 °C, up to 2,500 m altitude and high humidity environments.

Product Features

- Total capacity 5,000 kW with fine resolution load steps (100 kW resolution) and specific step bank layout (100kW + 200kW + 200kW + 500kW + 1,000kW ×4).

- Resistive elements: 8020 Ni–Cr alloy finned resistors; cooling by forced air (axial fans), horizontal intake and vertical outlet; noise

- Control & monitoring: local panel switching and remote PC operation, PLC, Modbus TCP, software that saves/prints load data; digital meters for voltage, current, power, power factor and frequency.

- Protections include high temperature, low air volume, phase sequence, short circuit, fan interlocks, access control, temperature & humidity control, and emergency stop.

- Expandable: parallel expansion of multiple load units; containerized construction with lift lugs for movement; meets international/ship/military/telecom standards.

Product Value

- Provides accurate, reliable, and repeatable high‑power load testing (loading accuracy ≤ 3%, 3‑phase unbalance ≤ 3%) to validate generator sets, power plant equipment and protection systems.

- Reduces commissioning and maintenance time by enabling on‑site, continuous, no‑prep load testing—helps detect performance issues before they become critical.

- Remote control and data logging improve test repeatability and recordkeeping for compliance, acceptance testing and operational benchmarking.

- Containerized, robust design allows outdoor installation and operation in harsh environments, minimizing infrastructure needs.

Product Advantages

- High capacity (5 MW) at high voltage (11 kV) in a single, transportable container—suitable for large generator sets and power plants.

- Flexible control (local and remote), fine load granularity and parallel expansion for scalable testing scenarios.

- Rugged design with comprehensive safety/protection systems and international standard compliance for use in demanding industries (marine, military, telecom).

- Low acoustic footprint for its class and efficient forced‑air cooling ensures long‑term continuous duty.

- Customizable (voltages, control interfaces, optional features) and backed by a 12‑month warranty from commissioning.

Application Scenarios

- Commissioning and routine load testing of gas‑fired power plant generator sets and large standby generators.

- Performance verification, acceptance tests and maintenance of utility and industrial generators, switchgear and protection systems.

- Telecom, data center and UPS system load testing where high‑power, controlled resistive loads are required.

- Military, shipboard and offshore platform testing where containerized, standards-compliant equipment is needed.

- Training, research and temporary load support during grid works, plant upgrades or failure simulation exercises.
