These 3-phase pad-mounted transformers are built tough for utility and industrial use. They step down power from 34.5 kV to either 13.2 kV or 13.8 kV. Standard power ratings are available: 1000 kVA, 1500 kVA, 2000 kVA, and 3000 kVA. You might also see these listed as 1 MVA, 1.5 MVA, 2 MVA, or 3 MVA. Sometimes people say 1 MW or 1.5 MW meaning the same power level. They handle heavy loads reliably.

The transformers sit inside sturdy, tamper-proof steel enclosures. These enclosures protect the internal components. They keep the transformer safe from weather, animals, and unauthorized access. The enclosures are filled with dielectric fluid. This fluid provides insulation and cooling. The design prevents leaks and contamination. Access points are secure. Only qualified personnel should open them.

Installation is straightforward. They mount directly onto a concrete pad at ground level. This saves space compared to pole-top units. It makes maintenance easier too. The compact footprint suits crowded areas like subdivisions, commercial sites, and industrial parks. Connections happen through pad-mounted compartments. Primary and secondary cables enter through conduits underground. This keeps things neat and safe.

Inside, high-quality core and coil assemblies ensure efficiency. They minimize energy loss during operation. The transformers use reliable ONAN cooling. This means oil natural, air natural. The oil circulates naturally inside the tank. Air flows naturally over the external cooling fins. This simple method works well for standard duty cycles. They last long with minimal fuss.

These units meet strict industry standards. They are built for safety and durability. Routine checks are needed. The fluid level and connections should be inspected periodically. They deliver consistent power for demanding applications. Their robust construction handles daily operation. They are a practical solution for distributing medium voltage power reliably.

Applications of 3 Phase Pad Mounted Transformer 34.5 Kv 13.2kv 13.8kv 1000kva 1500kva 2000kva 3000kva 1500 3000 Kva 1mva 2 1.5 Mva 1mw 3phase

These 3-phase pad-mounted transformers handle tough jobs. They step down high voltage power. Common voltages include 34.5kV to 13.2kV or 13.8kV. Capacities range from 1000kVA up to 3000kVA (1.5 MVA, 2 MVA, 1 MW). Their robust, enclosed design sits right on the ground. This makes them perfect for many demanding situations.

Cities and towns rely on them heavily. They distribute power safely underground. They feed entire neighborhoods, apartment complexes, and housing developments. The compact size matters here. They fit easily in tight spaces near sidewalks or green areas. Maintenance crews access them fast.

Commercial areas use them constantly. Think shopping centers, office parks, and hospitals. These places need reliable power. The transformers deliver it efficiently. They handle the big loads from air conditioning, lighting, and equipment. Underground connections keep streets clear and safe.

Industrial sites demand rugged equipment. These transformers deliver. Factories, warehouses, and processing plants count on them. They power heavy machinery, motors, and production lines. The 1500kVA, 2000kVA, and 3000kVA units are common here. They handle the intense, constant electrical loads.

Utility companies install them widely. They form key points in the power distribution grid. They help regulate voltage. They improve reliability for whole sections. Their pad-mounted design saves space. It avoids the need for large substation yards in crowded spots.

Renewable energy projects need them too. They connect solar farms or wind installations to the existing grid. They step up or step down voltage as required. This ensures smooth power flow into the system.

Schools and universities use them. They provide safe, reliable power across campuses. Critical facilities like hospitals depend on their consistent performance. They keep life-saving equipment running. These transformers are built tough. They withstand harsh weather. They operate reliably for years. They are a fundamental part of modern electrical infrastructure.

5 FAQs of 3 Phase Pad Mounted Transformer 34.5 Kv 13.2kv 13.8kv 1000kva 1500kva 2000kva 3000kva 1500 3000 Kva 1mva 2 1.5 Mva 1mw 3phase

What places use these transformers?
These transformers work well in many spots. They fit power stations, business parks, and large buildings. They step down high voltage from utility lines to usable levels for equipment. You see them near factories, hospitals, and big shopping centers. They handle heavy power needs safely outdoors.

What voltages do they handle?
Primary voltage is usually 34.5kV. Secondary voltages are commonly 13.2kV or 13.8kV. Confirm your exact supply voltage matches the transformer’s input rating. Match your required output voltage to the secondary side. Getting this right prevents damage.

How do I pick the right size?
Choose based on your total electrical load. Common sizes are 1000kVA, 1500kVA, 2000kVA, and 3000kVA. These equal 1MVA, 1.5MVA, 2MVA, and 3MVA. Calculate your peak power demand. Add some extra capacity for future growth. A 1500kVA unit suits many medium industrial needs. A 3000kVA unit handles very large loads.

Are they safe?
Yes, safety is a key feature. They have a locked steel tank protecting internal parts. The tank is tamper-proof. They include pressure relief devices for overloads. Fault indicators warn of internal problems. Install them according to local codes. Maintain clear space around them for air flow and safety access.

How much maintenance is needed?
These transformers need very little routine care. They are sealed units filled with oil for cooling and insulation. Check oil levels yearly through the gauge. Look for leaks. Keep the area clean. Listen for unusual humming sounds. Schedule professional inspections every few years. They are built for reliable, long-term service with minimal upkeep.
