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 provided by Guilin Sanhua Mechanical&Electronical Automation Engineering Co.,Ltd.Normal Service ConditionsNormal service conditions of switchgear following:Ambient temperature in room:Maximum                                       +40°CMaximum 24 hour average         +35°CMinimum (according to "minus 15 indoor class")     -15°CAmbient humidity in room:                        95% and lessDaily average relative humidity                  less than 95%Monthly average relative humidity            less than 90%Height above sea level at site                      less than 1000mEarthquake intensity:                                    less than 8 degreeThis product should not be used under conditions of fire, explosion,earthquake and chemical corrosion environments.2.
