People have higher and higher requirements for the appearance of the substation box. The substation box must not only be safe and reliable, but also be neat and beautiful, able to blend with the surrounding environment, which is beneficial to the improvement of the image. The designer took into account the environmental factors of the substation box, and carried out design innovations in terms of shape, material, technology, and man-machine to ensure the mechanical strength of the product, and ensure the reliability and service life of the use. In terms of appearance design, the shape is neat and generous, and the surface technology is exquisite, giving people a simple, fashionable and beautiful visual experience. The substation box has a compact structure and reasonable layout. The shell is composed of double-layer, sealed, moisture-proof, and rust-proof materials. It adopts fully insulated and fully protected design, corrosion resistance, high reliability, and strong environmental adaptability. The substation box design pays more attention to details, modular design, free combination, convenient and flexible access lines. The upper and lower parts of the box are provided with vents, oval three-dimensional design, and the ventilation effect is good. The innovative flap door can reduce the footprint of the sidewalk during maintenance, and the cooling plate is cleverly combined with the inspection pedal to reduce the volume of the equipment. The connection between the base, frame, door and top cover adopts labyrinth structure, which is waterproof, dustproof and prevents small animals from entering. The electromagnetic shielding design is done to prevent disturbance to electronic components and ensure reliable operation of electrical equipment.
