1. GENERAL
1.1 The modular low-voltage switchgear system MNS is a type tested factory-built switchgear assembly(FBA)in accordance withIEC4391,VDE660,part 500,BS5486 part 1,UTE63-410.The cubicle used for shipping should also conform to Lloyd,s Register of shipping.
The structure of MNS switchgear is of two variwties;the fixed type and the withdrawable type,its selective materials are classified as the sheet steel structure and the plastic structure,the technology of which reaches 80s,international advanced level.
MNS system are suitable for use in all installations where electrical enetgy is generated,distributed and utiliced and are widely used as disteibution system in power station 、nubbbbb power station 、shipping、oil placform and other enterprises.
1.2 FEATURES
*Compact,space saving design.
*High generalization in structure design and flexibility in makeup.The Cprofiles of sheet steel with 25mm modular interval can meet the needs of all kinds of strucrural types、protetion degrees、operating and enyironmental conditions.
*Adoption of standard module design:They xan make up avariety of standard units for protection、operating、switching、controlling、regulating、measuring and indication.The user may choose at option the relevant standard unit for assembly according to requirement.
Up to more than 200of structure parts and functional modules make it possible to make up a variety of structrue frames and drawer units for sifferent schematic requirememts.
*Adoption of arge number of the high strengthy flameresisting plastic modulars and functional partirion plates are effextive to strengthen the performance of safety protection.
*High technical characteristics,main bbbbbeters reach afairly high international advanced level.
*Reduction in space requirement for storing and transporting prefabricated parts thanks to the high degree of seriation,standardization and generalization of the structrue.
