GROADA-AC load cabinet was photographed in November. guangluda load co., ltd. independently developed and produced load boxes. currently, it is exported to various countries in the world. this AC load series is a photo of some orders completed in November. due to limited photo width and space, only some products were photographed. Packed and shipped on the afternoon of December 5.

Main components

resistive load

The resistive load is composed of multiple special alloy resistors in parallel. The outside of the alloy resistor is made of stainless steel sheet as heat dissipation material, the outer tube is made of stainless steel tube as anti-rust and anti-corrosion component, and the inside is filled with heat conduction and insulation medium magnesium oxide powder, and the power consumption component nickel-chromium alloy resistor is encapsulated in it. 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.

inductive load

Inductive load module consists of a number of fixed reactors, the main purpose is to adjust the inductive load in the load test, with the resistive/capacitive load, adjustable load power factor, simulation of the actual working state of the inverter, generator set. After the coil and core of the reactor are assembled into one body, they are pre-baked, vacuum impregnated with paint, dried and cured, so that the coil and core of the reactor are firmly combined. Low loss, high efficiency, low temperature rise, long-term stable operation under rated load. No noise, no pollution, no daily maintenance, long service life.
