Package & Unit Substations

Factory-assembled, fully type-tested compact MV prefabricated substations engineered for global power utilities, industrial facilities, and infrastructure developments.

Engineered for Heavy-Duty Utility & Industrial Infrastructure

EUROGULF Transformers manufactures standard and custom-engineered Package & Unit Substations up to 36 kV class in our 100,000 sq ft state-of-the-art facility located in Hamriyah Free Zone, Sharjah, UAE. Built to meet stringent regional and international energy standards, our substations form a critical link in medium-voltage electrical distribution networks worldwide.

Designed specifically for underground power reticulation networks in urban, industrial, commercial, and utility environments, EUROGULF substations combine high-voltage switchgear (Ring Main Units), oil-immersed or dry-type step-down distribution transformers, and low-voltage switchboards within a unified, fully enclosed compartment housing. Factory-assembled and tested prior to export, our substations eliminate site integration risks, optimize spatial footprints, and simplify field installation.

Integrated Factory-Assembled Compartments

Each EUROGULF Package Substation is structured into three thermally segregated, metal-partitioned compartments designed to maximize operational safety, maintenance convenience, and environmental protection:

  • High Voltage Compartment: Outfitted with SF6-insulated or Vacuum Ring Main Units (RMU) featuring breaker/switch-fuse combinations, pressure-relief safety vents, and interlocking mechanisms.
  • Transformer Compartment: Houses hermetically sealed oil-immersed distribution transformers or cast resin dry-type transformers engineered for low-loss, high-efficiency operation.
  • Low Voltage Compartment: Configured with high-breaking-capacity circuit breakers (ACB/MCCB), busbars, metering instruments, power factor correction, and outgoing feeder protection.

Key Engineering Advantages

Internal Arc Tested

Designed and type-tested to withstand internal arc faults (IAC classification) in accordance with IEC 62271-202, ensuring maximum safety for operating personnel and public surroundings.

Harsh Environment Ready

Enclosures built with Cor-Ten steel, electro-galvanized sheet, or Glass Reinforced Concrete (GRC) rated IP34 to IP54 for extreme ambient desert heat (+55°C) and corrosive coastal humidity.

Plug-and-Play Installation

Fully wired, inter-connected, and rigorously FAT-tested prior to dispatch. Minimizes civil works and dramatically reduces site commissioning timelines for procurement contractors.

Eco-Efficient Operation

Utilizes energy-efficient low-loss transformer cores (CRGO steel), environmentally friendly dielectric fluids (biodegradable synthetic esters available), and low acoustic footprint design.
