Busbar Compartement

System highlights

- Maintenance free busbar construction- Easy switchgear extension- Main busbar arrangement at the rear thusassuring- Maximum safety to personnel- Effective withstand against highest stresses in case of short circuit of short circuit- Optimum heat dissipation- Gas tight seals for connection from the- Equipment compartment to the main busbars system- Option for Form 4 separation for bothincoming and outgoing assemblies- Active and passive arc fault prevention tested according to IEC 61641 according to IEC 61641- Isolating materials are free of CFC and halogens.

Structure

The factory-assembled and standardized switchboard MCP-10 are composed of one or more vertical sections making a homogeneous whole for single front mounting.The min. thickness of sheet steels is 2 mm.On such basic structure are mounted the hinged doors, On such basic structure are mounted the hinged doors, the cover panels, the partitions and the supports for the busbars and the shelves which delimit cubicles size.On the front each cubicle is closed by individual door as for the cable compartment, while the rear of the switchboard is usually closed by a common removable cover panel.The structures are built-up in independent cubicles that can be coupled each other to realize cubicles that can be coupled each other to realize switchboards that cater for all installation requirements.

The cubicles are divided in three compartment:- Main and distribution busbar compartment placed on the rear part- Equipment compartment, on the front, for withdrawable and fixed units- Cable compartment, on the front, for auxiliary and power - Cable compartment, on the front, for auxiliary and power cable connection.

Cubicles are realized in such a way as maintenance or component replacement are carried out form the front and here below their composition:

Busbar Compartment

The main busbar system is located in the rear part of the cubicles and serves to distribute the current to the cubicle cubicles and serves to distribute the current to the cubicle forming the switchboard.It is made by flat bars of electrolytic copper that are held by suitable bar holders dimensioned to carry out service andshort circuit currents. The special copper tee distribution busbar system run vertically in the rear part of each cubicle.

This system, shunting from the main one, serves todistribute the current to the various cells of the vertical section and it withstands a max. 2000 A current.At the switchboard bottom is located the earthing bar.

Withdrawable Unit Compartment

The framework construction has been designed with modular principle in order to be divided into feeder compartments variable both in quantity and dimensions starting from the unit having the smallest size of 1 modules up to 10 modules in the whole.The feeder compartment can be composed either in The feeder compartment can be composed either in fixed or withdrawable units.The partition between two units has been realized by mean of metal shelves inside of them, in case of the withdrawable version, is placed the mechanicalinterlock of the unit. One or two withdrawable unit limit switches may be provided as optional.Each cubicle is provided with a dooprovided with a door, including seal on request,insulating grid with protection degree IP20 for introducingwithdrawable unit clamps to the distribution busbarsystem, the fixed portion for sliding contacts, the fixed terminals and relevant protection.

Cable Compartment

Sufficiently dimensioned as to assure an easy connection of power, control and indication cables to the terminal boards thereof.On the right side of the feeder compartment it is realized the cable compartment having height like whole cubicle.All terminal blocks are accessible from the front and are All terminal blocks are accessible from the front and are suitably protected in order to allow the connection of the cables to the users also with all the other cubicles live.The outgoing cables are fastened on the side of the rear part of the structure by means of suitable support brackets.The cables incoming or outgoing is possible both from the top or the bottom by means of removable plates for the eventual installation of cable glands.eventual installation of cable glands.A copper flat bar connected to the earthing bar, to which all the cable earth braids can be connected, is provided as optional.

One set of mechanical and electrical interlocks grant the correct operation of the unit, the good preservation of thesame and the safety of the operator.Inside its own unit the input clamps can have three positions:- Isolated (Off)- Test- Connected (On)- Connected (On)The three positions are automatically indicated outside by means of an indicator situated on the front operating plate.

Withdrawable Unit

The withdrawable unit is an apart functional unit and therefore is completely independent from all the other mounted on the switchboard.Each withdrawable unit is interchangeable with all the other having the same size and electrical configuration.The following essential elements are part of a The following essential elements are part of a withdrawable unit:- Front control and signaling plate- Sturdy and compact folded steel sheet structure - Sliding auxiliary contacts- Output finger clamps- Output clamps base- Output clamps base- Input finger clamps- Limit switches operating cams, housed in the operating mechanism of the withdrawable unit.The operating mechanism of the unit grant a perfect functionality to avoid any false operation of the operator.

Surface Finishing

The metal structure and the internal segregations are made by steel sheet protected against corrosion and ageing by means of the “zinc alum” galvanizing system.The doors and cover panels are made by painted steel sheet.For tropical or very corrosive climate the doors and For tropical or very corrosive climate the doors and cover panels will be protected by electrolytic galvanizing. The doors and cover panels are moreoversubjected to painting, carried out in a continuous automatic cycle including the following operations:- Washing- Degreasing- Organic passivation- Organic passivation- Drying- Painting by polymerised powder (60 micron min. 100 micron max. baked at 180 degC).Standard colour is light grey (RAL 7032). n request other colours can be provided.

Surface Treatment

- Optimum continuity of the protective Circuits- High degree of corrosion protection- All items normally touched during assembly and installation of a switchboard are de-burred and rounded

Module compartment components are made of Aluzinc or Galvanized

Doors and covers Finishing by polymerised powder coating
