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.
