Fully oil-filled pad-mounted substations

Introduction to Fully Oil-Insulated Pad-Mounted Substations

Fully oil-insulated pad-mounted substations are among the most advanced solutions for power distribution in urban, industrial, and commercial environments. Featuring an integrated design and fully prefabricated components, these substations represent a new revolution in the power industry. All components, including transformers, switches, fuses, and protection systems, are housed in an oil-filled compartment that is completely insulated. This structure enhances safety, reduces installation and maintenance costs, and accelerates commissioning processes.

Key Advantages of Fully Oil-Insulated Pad-Mounted Substations

• Prefabricated structure with easy transportation and fast on-site installation
• Optimized design for limited spaces with minimal land usage
• High safety due to enclosed oil tank and reduced fire risk
• No need for substation buildings, lowering civil construction costs
• Resistant to harsh environmental conditions, dust, and humidity with IP54 protection rating

Outstanding Technical Features

These pad-mounted substations are designed and manufactured in accordance with international standards such as ANSI C57.12.26 and ANSI C57.12.29. They have a thermal class of 0, ensuring safe operation under various load conditions. The use of rotary oil switches for load-break operations ensures long-term performance stability. In addition, Bay-O-Net fuses combined with current-limiting backup fuses offer dual protection against overload and short circuits.

Application Areas

These substations are ideal for projects with limited space or high safety requirements. Common application areas include:

• High-density residential projects in urban areas
• Factories and industrial zones requiring safe and reliable power
• Commercial centers and hospitals where power reliability is critical
• Remote areas where traditional infrastructure is challenging

Economic and Environmental Benefits

The use of fully oil-insulated pad-mounted substations leads to significant savings in installation and maintenance costs, as well as reduced usage of construction materials and space. These benefits, along with fast installation and shorter commissioning time, enable quicker project completion. From an environmental standpoint, the isolated design and elimination of additional structures help minimize environmental pollution.
