Where it's deployed
Rapid-deployment power for the projects that define the Saudi skyline.
Factory-built and outdoor-rated means site work is limited to cable connection. Package substations are specified wherever deployment speed, repeatability, and uniform quality matter more than a brick-built footprint.
- 01
Vision 2030 megaprojects
NEOM, the Red Sea Project, Qiddiya, and other giga-projects requiring rapid, repeatable power infrastructure deployment. Smart configurations integrate with project-wide SCADA.
- 02
Renewable energy plants
Solar PV plants requiring distributed step-down substations across large land areas. The smart configuration enables remote monitoring of dozens of substations from one control room.
- 03
Urban distribution networks
Saudi Electricity Company distribution expansion. Package substations replace traditional brick-built substations for faster deployment and consistent quality.
- 04
Real-estate developments
Master-planned residential and mixed-use communities. Single-supply package substations serve as the development's electrical backbone.
- 05
Industrial sites
Heavy industry, manufacturing complexes, and logistics hubs requiring high-quality step-down power at multiple locations across a campus.
- 06
Infrastructure projects
Airports, ports, metro systems, and highway corridors. Applications where on-site assembly time is constrained and reliability is non-negotiable.
Four package substations tapped off a single 33 kV feeder, each feeding a local load. The deployment shape that Vision 2030 megaprojects, solar plants, and SEC urban networks share.
Engineered to standard
Type-tested. Site-ready. Smart-capable.
The package substation family is designed and type-tested against the IEC and DIN switchgear series, with the certifications a Saudi industrial buyer expects.
IEC and DIN standards compliance
- IEC 62271-100HV AC circuit-breakers.
- IEC 62271-102HV AC disconnectors and earthing switches.
- IEC 62271-103Switches above 1 kV up to 52 kV.
- IEC 62271-105AC switch-fuse combinations.
- IEC 62271-200AC metal-enclosed switchgear up to 52 kV.
- DIN VDE 0670 / 0671German standards for European compatibility.
