Import 500kw Load Bank — Buy in wholesale FOB from Supplier in China

Hebei Kaixiang Electrical Technology Co., Ltd manufactures this 500 kW resistive load bank for testing and commissioning AC power systems at 400 VAC, 3-phase 4-wire, 50/60 Hz. The unit delivers a maximum load power of 510 kW at 400 V with a power factor of 1, using precision alloy resistors arranged in eleven load steps: 1, 2, 2, 5, 10, 20, 20, 50, 100, 100 and 200 kW. Each individual step tolerates 5% variance, while overall load tolerance is held to 3%, monitored via a multifunction meter with RS232/RS485 communication for remote data logging and control.

The load bank employs forced-air cooling with horizontal intake and exhaust through louvered ports, designed for continuous outdoor operation from -20°C to 50°C at altitudes up to 2500 metres and relative humidity up to 95%. Siemens PLC controls step switching with MIRO fuses and contactors providing circuit protection. The alloy resistor elements are rated for sustained thermal duty, and the entire assembly is housed in a powder-coated steel enclosure finished in grey RAL7035 or yellow. Standard transport fittings include lifting eyes and castor wheels for site mobility.

This equipment serves generator set manufacturers, data centre commissioning teams, marine electrical contractors and utility maintenance departments who need to verify UPS, diesel generator and turbine output under controlled load conditions. The star-coupled input busbar accepts direct cable termination, while control power requires a separate 380 VAC 3-phase 4-wire 50 Hz supply. Buyers should confirm commissioning support, spare resistor availability and whether Data Processing Software is included or licensed separately before finalising procurement.

Hebei Kaixiang Electrical Technology Co., Ltd operates from No.33, Wangshan Road in the Luquan Economic Development Zone, Shijiazhuang, Hebei Province, postal code 050221, China. The supplier holds a harbor trust tier on the marketplace, though its published response rate is 0.00% with zero average response hours recorded, suggesting limited or no engagement through platform messaging channels. Buyers should anticipate that direct contact via the listed address or alternative channels may be necessary for quotations and technical clarification.

The company's specialisation centres on electrical test equipment, specifically load banks for power system validation. Its product incorporates branded components from Siemens (PLC), MIRO (fuses and contactors) and Mitsubishi (implied through standard industry sourcing for similar equipment), assembled with alloy resistor technology. No information is provided about factory certifications such as ISO 9001, manufacturing scale, annual turnover, or client references. Prospective importers should request a company profile, quality management system documentation and reference installations before committing to an order.
