STANDARD ENCLOSURES

 

Enclosure:

 

(NCEI) uses any IEC standard circuit breakers, type tested enclosures, ( Blokset & Prisma enclosures or approved equal)to accommodate the switch boards, which are mainly manufactured by SCHNEIDER ELECTRIC.

 

Such enclosures (Blokset) are functional system for electrical switchboards up to 6300A and classifieds as follows:

 

1. Electrical Switch boards up to 630 A :

 

These types of enclosures can be build all types of main, secondary and final low voltage switchboards up to 630 A for industrial and commercial buildings.

 

The same components, wheter for switchgear installation, current distribution, cable etc. may be installed in any of three types of enclosures or cubicles, depending on the size of the switchboard and the site installation requirements.

3. Custom Built Enclosures up to 6300A :

 

                   Such enclosures are applicable in special cases when the space is not enough to accommodate the standard enclosure.                      Fabrication of non-standard enclosures is necessary to maintain the quality, safety and reliabilty.

 

                   Engineering design offices make their own design and calculations to meet the international electrical standards                                  without deviations.

 

                   (NCEI) use type tested enclosures Blokset type (Schneider Electric) manufacture. or (NCEI) can be fabricate such                                       enclosures which can be used to accommodate up to 6300A.

                  NCEI manufactures package & unit substations as per IEC standards up to 3150KVA capacity (Oil & Dry Type Transformer)                   with high voltage up to 36kV and LV as required. These types of enclosures are designed specially for medium voltage                         distribution networks. The main parts of the kiosk and the general characteristics are:

 

     4.1  Skid Base :

                  Skid base is made of U-Channel 120 x 120 x 12 mm and depends more or less on the equipments to accommodate. Special                   treatment has to be carried out on the U-Channel before galvanizing. Different sizes of skid bases are fabricate according                   to the equipment rating.

 

     4.2  Canopy :

                  Canopies are made of dual roof galvanized steel sheets of 2mm thickness with air insullation provided between inner                         and outer roof to avoid internal temperature rising.

 

     4.3 Side Covers and Doors:

                  Side covers and doors are made of galvanized steel sheets of thickness of 2mm minimum,well tightened to the skid base                   and canopy. Each side of the kiosk has a door provided with enough number of louvers to ensure sufficient natural air                       ventillation for cooling the transformer and the equipment. Inlets and outlets of air provided with screens for protection                   against access of vermin.

 

      4.4 General Characteristics of Kiosk :
