Features
The RYDS type low-voltage fixed partition switchgear is suitable for industries such as power plants, petrochemical, metallurgy, textiles, and power supply for high-rise buildings. In large power plants and petrochemical industries with high automation levels that require computer interfaces, it serves as a power distribution, conversion, and motor control system in three-phase AC frequency 50HZ, with a rated working voltage of AC 380V and a rated current of up to 4000A and below.
Structural Features
The fixed partition cabinet adopts a universal cabinet form, with the main structure made of 8MF steel, partially welded and assembled, and has installation holes of Φ9.2 with a module of 20mm. The components of the universal cabinet are designed according to the modular principle, with different numbers of heat dissipation slots at both ends of the cabinet. The cabinet body is connected to components via a pivot-type movable hinge, and the outer edge of the door is embedded with a rubber strip. The external metal structural parts, doors, sealing plates, and frames are treated with powder coating, while internal supports are galvanized; the protection level of the cabinet body is IP30.
