Specifications of 500kva 1500kva 2000kva 2500kva 3750kva 7.2/12.47KV 7.62/13.2KV 13.8KV-240V Loop/Radial Feed Three Phase Pad Mounted Transformer

Here are the specifications for our pad mounted transformers. These units handle capacities from 500kVA up to 3750kVA. They are built for three-phase power systems. The primary voltage options are 7.2kV, 7.62kV, 12.47kV, 13.2kV, and 13.8kV. The secondary voltage is consistently 240V. These transformers work well in both loop feed and radial feed network setups. This flexibility helps different utility connection needs.

Construction is robust. The enclosure is heavy-duty steel. It protects internal components reliably. The tank is welded for a permanent, leak-proof seal. This design ensures long-term performance outdoors. Units include sturdy lifting hooks. This allows safe and simple installation and handling. Cooling is efficient. It uses mineral oil and corrugated tank walls. This provides effective heat dissipation. This keeps the transformer running cool under normal load conditions.

Safety features are important. Tamper-proof hardware is standard. Padlocking provisions are included on all access points. This prevents unauthorized entry. Reliable grounding points are clearly marked. Proper grounding is essential for safety. Internal components are top quality. The core uses high-grade electrical steel. Windings are copper or aluminum. Both materials perform well. The design minimizes losses. This improves overall energy efficiency.

These transformers are versatile. They suit many commercial and industrial applications. Common uses are office parks, shopping centers, and manufacturing plants. They provide reliable voltage transformation. They step down medium voltage to usable low voltage. The compact pad-mounted design saves space. It avoids the need for large substation buildings. Installation is straightforward. Units mount directly onto a concrete pad. This makes them a practical solution. They meet standard utility requirements. They deliver dependable power distribution.

Applications of 500kva 1500kva 2000kva 2500kva 3750kva 7.2/12.47KV 7.62/13.2KV 13.8KV-240V Loop/Radial Feed Three Phase Pad Mounted Transformer

These transformers power essential infrastructure across communities and industries. Their 500kVA to 3750kVA capacity range handles significant electrical loads. Common voltage ratings like 7.2/12.47kV, 7.62/13.2kV, and 13.8kV on the primary side connect directly to utility distribution lines. The standard 120/240V secondary output supplies three-phase power for buildings and equipment.

Loop feed operation is a major application. Transformers connect in a loop configuration within a neighborhood or business park. Power flows from two directions. This design improves reliability. If one source fails, power often continues from the other direction. Service interruptions decrease significantly. This setup is common in residential subdivisions, shopping centers, and critical facilities needing high uptime.

Radial feed applications are widespread too. Here, power comes from a single source, feeding downstream transformers or loads sequentially. It’s a simpler, often more cost-effective solution for extending power lines. Radial feed works well for commercial strips, light industrial areas, or feeding individual large facilities where a loop isn’t necessary. These pad-mounted units provide the step-down right where power is consumed.

Industrial sites rely heavily on these transformers. They power machinery, lighting, and HVAC systems in factories, warehouses, and processing plants. The units are placed outdoors near buildings, saving valuable indoor space. Their robust, tamper-resistant enclosures protect components from weather and unauthorized access. Oil or less-flammable fluid insulation ensures safe operation.

Renewable energy projects use these transformers. They step down voltage from solar farms or wind turbine collection points before feeding power into the grid. Their pad-mounted design integrates well with ground-mounted solar arrays. Utilities deploy them extensively for standard neighborhood distribution. They deliver power reliably to homes and businesses day after year. The 240V output efficiently supports three-phase motors and heavy equipment common in commercial and industrial settings. These transformers are the workhorses stepping down power for daily use.
