The internal structure of the GROADA-AC120V-30KW-R resistance load box is a resistance bar, which will be ordered on November 1, 2022. The company will complete the production and testing according to the requirements of Party A and within the specified time, and ship it to Shenzhen Baoan on November 12, 2022. The purchaser is a Shiyan Skyworth Industrial Technology Co., Ltd. At present, the two products have been put into use, and the products are in good running condition and under normal testing.

The GROADA-AC120V-30KW-R resistance load box products independently developed and produced by Guangluda have been used in many fields at home and abroad. They are mainly used in the performance testing and aging of online high-power UPS, inverters, switching power supplies and diesel generator sets of electric power, telecommunications and other departments and manufacturers. Unified segmented power input, energy-consuming working mode, forced air-cooled heat dissipation, greatly ensuring the reliability of constant power discharge; internal heat dissipation components using dry resistance, forced air-cooled heat dissipation. Produced with independent intellectual property rights of new power consumption components, it has high power density, no red heat phenomenon, and automatic overheating protection function. When the fan does not rotate, there will be no overheating or burning, and it has a long safe life. Modular design, simple operation and convenient maintenance; parameters such as voltage and current can be tested according to customer requirements, which provides a scientific detection method for high-power AC power supply equipment.

Resistive load box the overall structure is connected by a number of special nickel-chromium alloy resistors. Alloy resistance as a power consumption component, manufactured by special alloy processing, the outside is made of 304 stainless steel heat sink, the middle is filled with insulating medium, the resistance is encapsulated in it, can meet the needs of load testing. The alloy resistance has good insulation performance, high heat dissipation performance, uniform heat conduction, the operating temperature is only 1/3 of the design temperature, the temperature drift is small, the resistance is stable, and there is no red heat for long-term work. And has the acid and alkali resistance, salt spray resistance, rain, moisture, anti-corrosion effect, can be used all-weather.
