Package Substations
A package substation combines MV switchgear, a transformer and an LV panel inside one factory-built, weatherproof enclosure, delivered to site as a single tested unit rather than assembled from separate equipment. NLS Power sources and supplies package substations built to IEC 62271-202 for compounds, labor camps, retail and industrial sites across Saudi Arabia, reducing on-site civil and electrical work.
A package substation, sometimes called a kiosk substation, puts the medium voltage switchgear, the transformer and the low voltage distribution panel into a single factory-assembled and factory-tested enclosure, built to IEC 62271-202. The whole unit ships to site as one piece, gets set on a prepared plinth, connected to incoming MV cable and outgoing LV feeders, and is ready for commissioning without the separate equipment room, cable basement and multi-week assembly a conventional substation build requires.
This matters most where the program is tight or the site has no dedicated electrical building: temporary or fast-track compounds, labor camps and worker accommodation, retail developments where a substation has to fit a small plot without competing for internal building floor area, and industrial or logistics sites where power needs to be live before permanent buildings are finished. Enclosures come in walk-in and non-walk-in configurations, the walk-in type giving maintenance access inside the unit itself, while a non-walk-in kiosk keeps a smaller footprint with all servicing done from external access panels.
Because the substation is factory-tested as a complete assembly rather than commissioned piece by piece on site, the coordination between the MV protection, transformer characteristics and LV distribution is verified before it ever reaches the project, which cuts a meaningful amount of site commissioning time. Corrosion protection and enclosure sealing need particular attention on Saudi projects: coastal sites need a higher-grade coating specification, and all sites need dust ingress protection matched to the exposure the unit will actually see once installed outdoors.
NLS Power sources and supplies package substations sized to the transformer rating, MV switchgear configuration and metering arrangement an SEC connection point requires, in walk-in or non-walk-in enclosure types matched to the site's maintenance access and footprint constraints.

Frequently Asked Questions
What's the advantage of a package substation over a conventional substation build?+
A package substation arrives factory-assembled and factory-tested as one unit, so it skips the multi-week on-site assembly, separate equipment room and piece-by-piece commissioning a conventional substation build needs. That makes it the faster option wherever program or site space is tight.
What's the difference between walk-in and non-walk-in package substations?+
A walk-in unit lets maintenance staff enter the enclosure to work on the equipment inside, which needs more floor area. A non-walk-in kiosk keeps a smaller footprint by putting all access panels on the outside, suited to sites where plot size matters more than internal working space.
Can a package substation handle Saudi outdoor conditions?+
Yes, provided the enclosure spec matches the site: IP54 or IP55 as a baseline, with an upgraded coating and gasket specification for coastal sites near Jubail or Yanbu where salt-laden air accelerates corrosion faster than inland locations.
