Electrical Substations

We provide end-to-end solutions for every variety of substation up to 500 kV. We take care of GIS and AIS equipment supply, installation, testing and commissioning. We can also provide system studies, substation automation, control and protection, telecommunications and all auxiliary services. 


We are the leading optical ground wires manufacturer in the Middle East. We produce HV & EHV cables up to 500 kV and offer integrated solutions for power transmission, power generation, substations and infrastructure. We can make any design with stainless steel or aluminum coated stainless steel tube (center or lateral) for OHTL of 66 kV, 132 kV, 220 kV, 400 kV or 500 kV. 

Laying methods 

  • Nose/end pulling 
  • Continuous end pulling 
  • Motorized rollers 
  • Caterpillar machines - cable pushers 
  • Manual 

Off-line and live-line installations 

Live-line installation of OPGW is essential when the power line cannot be shut down, for example, to keep a communication link between substations. Live lines will radically improve the communication infrastructure. We can: 

  • Replace ground wires with an OPGW to provide signal exchange and broadband communication
  • Extend and upgrade an existing OPGW below the top of the tower
  • Repair a defective OPGW

Testing & commissioning  

We carry out testing and commissioning for LV, MV and HV substations and the mobile power station balance plant. All our operation and maintenance personnel are fully trained for test and startup activities. 

Scope of work

  • 500 kV, 220 kV, 66 kV HV switch gears
