Drawing
Structural features:
The product design has fully considered the requirements of the majority of power users and design departments, which can meet the needs of the developing power industry such as the centralized control of capacity increase power, convenient installation and maintenance, and shortened accident treatment time, etc., which is safe, economical, reasonable and reliable.The product has the characteristics of strong connection ability, high breaking ability, good dynamic stability, flexible electrical scheme, convenient combination, strong series and practicability, novel structure and so on.At the same time, it can be combined with drawers and cabinets for mixed use.
Switch cabinet cabinet structure is composed of profiles (module E=25mm) assembly.As a result of using lock since tapping screw and 8.8 class high strength bolt for connection, thus high precision cabinet, good patience.
