These transformers supply power to neighborhoods and businesses. They manage three-phase electrical power. The key voltage is 11,000 volts. Second voltages prevail like 400 volts or 415 volts. Capabilities range commonly. Versions include 100kVA, 300kVA, 500kVA, 1000kVA (1MVA), 1500kVA (1.5 MVA), 2MVA, and 3MVA. The ideal dimension relies on the lots needed.

Mineral oil fills the tank. This oil cools down the transformer. It also protects the internal parts. The transformer uses ONAN air conditioning. This indicates oil circulates normally. Air streams normally over the tank surface. This technique functions well for standard rankings. The core makes use of top-quality electric steel. Copper or aluminum makes the windings. These materials make sure good efficiency and low losses.

The whole unit rests inside a strong steel tank. This storage tank is weatherproof. It mounts directly on a concrete pad. No different structure is essential. This conserves room and price. The container safeguards the transformer from the atmosphere. It also contains the insulating oil securely. Accessibility doors enable maintenance checks.

Internal components make use of oil-impregnated paper for insulation. This system deals with high voltage stresses accurately. Bushings link the high-voltage and low-voltage wires. These bushings are designed for underground network systems. They are reputable. They are safe. Stress relief devices protect against inner mistakes. An oil level scale reveals the oil amount. A thermostat shows operating temperature level. These attributes aid operators keep track of wellness.

These transformers are constructed tough. They withstand corrosion. They manage outdoor problems for years. They prevail under streets. They supply shopping centers. They power industrial parks. Safety is important. The tank is strong. It avoids leaks. It safeguards against criminal damage. Installment complies with stringent electric codes.

Applications of Three Phase 11kv 100kva 500kva 1500kva 2 3 Mva 100 300 1000 Kva Oil Electric Distribution Pad Mounted Transformer

These challenging pad-mounted transformers sit quietly on ground-level concrete pads. They handle the middle step in electricity delivery. Taking power straight from high-voltage lines at 11kV, they drop it down to much safer levels for areas and services. Their oil-filled layout maintains them great and protects interior parts, making certain trustworthy operation every year. Encased in secured steel cabinets, they stay safe and secure while blending right into metropolitan or industrial settings.

Different abilities serve distinctive demands. The smaller 100kVA systems are best for powering a few residences, a small shop, or a portable cell tower. Need even more muscle mass? The 300kVA to 500kVA models tip up. They easily handle larger structures like apartment complexes, schools, or medium-sized factories. Relocating right into the big league, 1000kVA transformers become important. They deal with significant loads for shopping mall, healthcare facilities, or huge office buildings. When industrial demand skyrockets, the 1500kVA, 2MVA, and 3MVA titans enter play. These powerhouses support hefty equipment, big manufacturing plants, or perhaps feed mini-grids serving entire commercial areas.

Their essential benefit is area. Being ground-level makes examination and upkeep far less complicated and much safer than pole-top systems. Employees don’t need unique lifts or considerable climbing up gear. The strong steel housing shields the important oil and core from weather, vandalism, and unexpected bumps. The oil inside isn’t just coolant; it’s superior insulation, allowing the transformer to take care of high tons effectively without overheating. This combination of easy accessibility, durable protection, and efficient cooling makes them the go-to choice for utilities and sectors needing reputable local power distribution. They create the crucial link between the high-voltage grid and the day-to-day power we make use of.
