As the Sultanate of Oman undergoes rapid industrial transformation through Oman Vision 2040, the demand for resilient power infrastructure has reached unprecedented levels. In regions like the Duqm Special Economic Zone (SEZAD) and the industrial hubs of Sohar and Salalah, traditional transformers face severe challenges from high ambient temperatures, salinity, and humidity. This is where Vacuum Pressure Impregnated (VPI) Dry-Type Transformers provide a critical technological edge.
Oman's temperatures often exceed 50°C. Our VPI transformers utilize Class H insulation (180°C) or Class R (220°C), ensuring operational stability without the fire risk associated with oil-filled units.
The vacuum pressure impregnation process ensures a solid, void-free coil structure, making our units ideal for heavy industrial applications and seismic-prone coastal infrastructure.
Aligned with Oman's green energy initiatives, VPI transformers are non-polluting, self-extinguishing, and require zero liquid containment, reducing maintenance costs by up to 40%.

In Oman’s industrial sector, the debate between VPI and Cast Resin (CRT) is ongoing. VPI transformers offer superior repairability—a vital factor for remote projects in Al Wusta or Dhofar. Unlike cast resin units, which often require total replacement if a coil fails, VPI units can be serviced and re-impregnated, significantly extending the life of the asset.
Our VPI system utilizes a sophisticated multi-cycle vacuum and pressure process, forcing high-grade polyester or silicone resin into the deepest layers of the winding, eliminating all air pockets (partial discharge) that could lead to insulation breakdown.
Global procurement for Omani projects requires strict adherence to OES and international IEC 60076 standards. Our export team ensures that all VPI units delivered to Muscat or Salalah meet:
With a growing international footprint, Henan Pirooz Power Co., Ltd. has exported its products to multiple countries and regions worldwide, building long-term partnerships across global energy markets. We understand the logistics of shipping heavy electrical equipment to the Port of Sultan Qaboos and Port of Salalah, ensuring secure packaging and "plug-and-play" readiness upon arrival.
In addition to transformers, the company provides complete electrical system solutions, including high and low voltage switchgear, European-style compact substations, American-style pad-mounted substations, and underground distribution substations. These integrated solutions are widely applied in power grid construction, industrial manufacturing, mining, metallurgy, petrochemicals, transportation systems, and renewable energy projects.

Cutting MachineVPI dry-type transformers are self-extinguishing and pose zero fire risk. They do not require oil pits or fire suppression systems, making them the preferred choice for Muscat's high-rise commercial buildings and malls.
Standard units typically ship within 4-6 weeks. Custom-engineered solutions for specific Omani industrial projects may take 8-12 weeks depending on complexity and certifications required.
Yes, Henan Pirooz Power Co., Ltd. offers comprehensive remote and on-site technical guidance for installation, commissioning, and maintenance through our localized partner network.
Our VPI process creates a non-hygroscopic coating. The resin fully penetrates the windings, leaving no gaps for moisture to enter, ensuring reliable cold-starts even in the most humid coastal conditions.
