Here are the specs for our high-performance single-phase pad mounted transformers. These units come in several power ratings. Choose 50kVA, 100kVA, 167kVA, or 250kVA models. They work for different voltage needs. The primary high voltage is either 11kV or 35kV. The secondary low voltage options are 110V, 220V/270V, or 440V. This covers many single-phase applications.

These transformers handle demanding environments. They sit outdoors on concrete pads. The enclosure is robust, weatherproof steel. It protects the internal components. This design prevents tampering and withstands tough conditions. The core uses high-grade grain-oriented silicon steel. This minimizes energy losses. Efficiency is a priority.

Cooling happens through mineral oil. It circulates naturally. This keeps temperatures stable under load. The oil preserves the insulation. Bushings are porcelain or polymer. They are designed for reliable cable connections. Primary bushings handle the high voltage input. Secondary bushings manage the low voltage output.

Standard accessories include pressure relief devices. They vent excess pressure safely. Liquid level gauges show the oil amount. Thermometers monitor operating temperature. Fill valves allow easy oil maintenance. Drains facilitate oil changes. Lifting lugs are strong. They make installation and movement straightforward.

Voltage adjustment is possible. Taps are on the primary winding. These taps let you adjust the output voltage slightly. This compensates for line variations. Connections are clearly marked. This ensures correct wiring. The design follows strict safety standards. This protects equipment and personnel.

Routine maintenance is simple. The design allows easy access for checks. These transformers deliver consistent power. They are built for long service life. Performance is reliable in diverse settings.

Applications of High-Performance Single-Phase 50kva 100kva 167kva 250kva 11KV/35KV 110V 220V/270V 440V Single Phase Pad Mounted Transformer

These single-phase pad mounted transformers handle tough jobs. They come in 50kVA, 100kVA, 167kVA, and 250kVA sizes. They step down higher voltages like 11kV or 35kV to usable levels. Outputs are common needs: 110V, 220V/270V, or 440V. Their high-performance design means reliable power in demanding spots.

One key use is powering remote areas. Think farms, cell towers, or small villages far from big grids. Three-phase power isn’t always available or needed there. These units bring essential electricity efficiently. They fit right on a concrete pad outdoors. No special building is necessary.

Industrial sites need them too. They feed specific machines needing single-phase power. Examples include large pumps, specialized ovens, or certain lighting systems. Having the right voltage directly at the machine saves money. It avoids long cable runs or extra conversion steps.

Renewable energy projects rely on them. Solar farms or small wind installations often connect single-phase inverters. These transformers boost the inverter output. They push the power efficiently onto the 11kV or 35kV distribution lines. They handle the variable nature of renewable generation well.

Construction sites use them for temporary power. They provide stable voltage for tools, trailers, and site lighting. Their pad-mounted design is secure. It protects against weather and unauthorized access. They are easy to install and move when the job finishes.

Railway systems sometimes use them. They power signaling equipment or station facilities needing single-phase feeds. Their durability suits the railway environment. They provide consistent power for critical safety systems.

These transformers are built tough. They withstand harsh weather, temperature swings, and demanding electrical loads. They offer a practical solution for many single-phase power needs. Their versatility makes them a valuable asset across different sectors.

5 FAQs of High-Performance Single-Phase 50kva 100kva 167kva 250kva 11KV/35KV 110V 220V/270V 440V Single Phase Pad Mounted Transformer

What does this transformer do?
It changes high voltage electricity to lower voltage. It steps down power from 11kV or 35kV systems. It delivers safer levels like 110V, 220V/270V, or 440V. This powers homes, small businesses, or specific equipment needing single-phase power. It mounts on a concrete pad near where the power is used.

What voltages can it handle?
The input is high voltage: 11kV or 35kV. The output is lower voltage. You get choices: 110V, 220V/270V, or 440V single-phase. The exact input and output combination is set when you order it. This matches your specific power lines and equipment needs.

Is it safe around people?
Yes, safety is a big focus. The design is “dead-front.” This means no live electrical parts are exposed outside the tank. The enclosure is very strong and tamper-resistant. It locks securely. This protects people and animals from accidental contact with high voltage. It also prevents unauthorized access.

How is it installed?
It arrives ready. You place it on a solid, level concrete pad outdoors. The location must be accessible for maintenance but follow safety clearances. Connections for the high-voltage power lines and the lower-voltage output cables are made inside sealed compartments. Proper grounding is essential. A qualified electrician must do the installation.

What maintenance is needed?
These transformers are built to run reliably for years with minimal care. The sealed tank protects the core and windings. Regular visual checks are important. Look for oil leaks, damage to the enclosure, or problems with the cooling fins. Check the external connections stay tight. Oil testing might be needed later. Always follow the manufacturer’s schedule.
