Product characteristics

☆ The conductive row in the rectifier cabinet is clamped with epoxy resin insulated I-shaped ladle, which has low vibration and noise.

☆ The internal conductive busbar is supported by high strength epoxy resin board to improve insulation performance.

☆ The radiator of rectifier components is made of copper radiator by one-time pressing. The radiator is in good contact with the components and the plane pressure is uniform, which can reduce the contact resistance and the component loss.

☆ Overvoltage protective devices are installed in isolation from the main circuit to prevent the main cabinet failure caused by the damage of protective devices and improve the safety performance of the main cabinet.

☆ The rectifier cabinet can adopt integrated design, which integrates the main rectifier cabinet, control cabinet, distribution cabinet, DC isolation switch and pure water cooler into a sealed container. This design can save installation space and prevent dust from entering.

☆ For the extremely cold and hot areas, air conditioning systems and insulation layers can be designed so that the equipment is not affected by the temperature of the external environment and the cabinet maintains a constant temperature state.
