Product Parameters

Performance characteristics

(1) The switchgear has high breaking capacity, good dynamic thermal stability, flexible electrical scheme, convenient combination and strong practicability.

(2) The main frame of the switch cabinet adopts 8MF steel, and the frame adopts two structural forms of assembly and partial welding. There are mounting modulus holes E = 20mm on the main frame, and the general coefficient is high.

(3) The switch cabinet has a complete grounding protection circuit to ensure the personal safety of the maintenance personnel.

(4) In order to strengthen ventilation and heat dissipation, there are ventilation and heat dissipation holes in the lower part, rear upper part and top of the cabinet body, so that the cabinet body forms a natural ventilation channel during operation and has better heat dissipation performance.

(5) The top cover of the cabinet can be removed when necessary to facilitate the assembly and adjustment of the main bus on site. The four corners of the cabinet are equipped with lifting rings to facilitate lifting and shipping.
