SMP Medium-Voltage Switchgear Air-InsulatedMetal-Enclosed
SwitchgearUp to 40.5KV1. GENERNAL DESCRIPTIONComplete Medium
Voltage Switchgear SolutionsSANHUA is a pioneer in the design and
manufacture of power distribution and protection equipment for the
electrical industry, offering a comprehensive range of medium
voltage (MV) solutions to meet the needs of virtually any
application.EXCELLENT EXPERIENCE:SMP air-insulated metal-enclosed
Medium-Voltage Switchgear provides users with a variety of
excellent experience with its Smooth operation, exemplary
availability and optimal safety.FLEXIBLE and CUSTOMIZABLESMP
Switchgear modular construction of the range allows SANHUA
Engineering's team of expert engineers to customise each medium
voltage power solution based on individual project specification.
Can be designed according to the user's operating habits. SMP
distribution cabinet can be deeply compatible with components of
various brands in the electrical industry, Users can specify
various brands of vacuum circuit breakers, protection devices,
current and voltage transformers, etc., Support deep
customization.MODULAR DESIGN CONCEPTThe SMP Switchgear system is a
modular concept based on the "building blocks" principle, which
means that cubicles are produced in series. As a result, the
modular SMP concept meets the highest technical standards in a
rational, economically sound way. The combination of cubicles is
unlimited. Very complex diagrams of distribution and transformer
switchgear can be compiled through this extensive spectrum of
possibilities. The semi-compact cubicles are particularly
beneficial if the available space should pose a problem or if
economical factors play an important role. Compartments also
contain all functional interlocks which allows for effortless
application, according to all current standards, and which allows
installation in consumer work spaces. As a result, capacity loss
will be minimal. Additionally, the compartments have been fitted
with a system for pressure release which shields the user from the
consequences of an internal arc.Typical application:1. Power
generation, transmission and distribution • Utilities
(National generation / transmission / distribution company)
• Private generation / transmission company •
EPC company and etc. • Power supply companies
• Energy producers • System operators.2.
Industrial plants and general industrial sectors •
Construction, EPC • Industrial plants, petrochemicals,
etc. • Buildings, landmark, hospital, etc.Standards and
SpecificationsThe switchgear complies with the standards of
IEC60298,GB3906,DL404 etc. Enclosure protection
degree of switchgear is IP4X, protection degree is IP2X when the
door of VCB room is open and the truck is be drew out.During the
installation and running of electric system, observe all the
relevant information in the IEC and the safety regulations in GB or
local electrical utility, and consider the relevant information
