Engineered for extreme ambient temperatures, heavy sandstorm environments, and strict international IEC/SEC grid reliability specifications.
The Kingdom of Saudi Arabia (KSA) is undergoing one of the most ambitious infrastructure and energy transitions in global history under Saudi Vision 2030. With massive multi-gigawatt renewable energy deployment, rapid electrification of mega-cities such as NEOM, the Red Sea Project, and Qiddiya, and major industrial expansions spearheaded by Saudi Aramco and SABIC in Jubail and Yanbu, the demand for precision measurement transformers (instrument transformers, CTs, VTs/PTs) and high-reliability power transformers has reached historic levels.
Measurement transformers serve as the foundational sensory organs of the electrical transmission and distribution architecture. They accurately step down high voltage levels (up to 110kV and 220kV) and heavy currents into safe, standardized secondary values (e.g., 1A, 5A, 100V, 110V) required by computerized protection relays, digital revenue metering systems, SCADA systems, and automated substation units.
Transformers installed in Saudi Arabia must withstand extreme thermal cycling, heavy dust storm abrasion, high salinity in coastal regions, and intense solar irradiation.
Unlike standard equipment rated for 40°C ambient temperatures, measurement and power transformers supplied to Saudi Arabia are engineered with heavy-duty Class H/F insulation materials, enlarged cooling radiator surfaces (ONAN/ONAF/ANAF), and lower temperature-rise limits (50/55K) to prevent premature insulation degradation during peak summer desert heat.
Frequent dust storms (Shamal) combined with coastal humidity in Jeddah, Dammam, and Yanbu generate severe saline-dust deposition on external insulators. Our equipment integrates high-creepage distance composite silicone rubber or heavily glazed porcelain bushings (exceeding 31mm/kV or 40mm/kV) to prevent external flashovers.
Industrial installations near petrochemical complexes and Arabian Gulf coastlines demand maximum ingress and chemical protection. Transformer tanks and measurement junction boxes feature IP56/IP65 ingress ratings, multi-layer marine-grade C5-M epoxy-polyurethane coatings, and hermetically sealed stainless steel nitrogen preservation systems.
From central utility substations to decentralized hybrid microgrids, our advanced transformer families provide unyielding electrical isolation, measurement precision, and voltage regulation across critical Saudi sectors:
Main transmission substations (110kV, 132kV, 220kV, and 380kV) rely on precision instrument transformers for differential protection, distance protection, and accurate revenue accounting across regional interties.
In massive renewable installations such as the Sudair 1.5GW Solar PV Project and Sakaka Solar Plant, our inverter-duty dry-type and oil-immersed transformers integrate dedicated measurement sensing to handle harmonic distortions, rapid power fluctuations, and bidirectional energy flows.
Hazardous zones in Aramco refineries and SABIC chemical plants require flame-retardant, anti-leakage, and special rectifier transformers engineered to supply stable DC power for electrolysis, smelting, and heavy induction drives.
