400kva 500 Kva 4000kva Three Phase Step Down Transformer 11kv To 400v 415v Pole Mounted Distribution Transformer

Overview of 400kva 500 Kva 4000kva Three Phase Step Down Transformer 11kv To 400v 415v Pole Mounted Distribution Transformer

An oil-immersed transformer is a type of electrical transformer where the core and windings are submerged in an insulating oil. This oil serves two primary functions: it acts as a highly effective insulator between conductive parts and as a coolant to dissipate heat generated during operation. These transformers are robust, reliable, and highly efficient, making them the standard choice for high-voltage power distribution and transmission networks, typically installed outdoors in substations.

Features of 400kva 500 Kva 4000kva Three Phase Step Down Transformer 11kv To 400v 415v Pole Mounted Distribution Transformer

• Effective Cooling: The insulating oil efficiently absorbs heat from the core and windings and transfers it to the radiator fins, allowing for natural or forced circulation and higher overload capacity.
• Superior Insulation: The oil provides much better dielectric strength than air, allowing for a more compact design for a given voltage rating and protecting against short circuits.
• Robust Construction: Designed for long-term, reliable operation (often 25-30 years) in harsh outdoor environments.
• Overload Capacity: Can handle temporary power overloads better than dry-type transformers due to the thermal mass and cooling properties of the oil.
• Protection System: Equipped with a conservator tank (to allow for oil expansion), breather (to absorb moisture from air), and protective relays (Buchholz relay) for internal fault detection.
• Cost-Effective: Generally more economical for high-power applications compared to dry-type transformers.

Applications of 400kva 500 Kva 4000kva Three Phase Step Down Transformer 11kv To 400v 415v Pole Mounted Distribution Transformer

These transformers take high voltage power from high-voltage line and make it secure for day-to-day usage. They tip down 11,000 volts to the usual 400 or 415 volts needed for factories, stores, and homes. Mounting them on poles conserves room and maintains them obtainable for upkeep.

Plant depend heavily on these systems. The 400kVA and 500kVA sizes handle equipment, big electric motors, and production lines inside factories. The bigger 4000kVA transformer powers whole industrial zones or huge facilities needing massive power. It makes certain hefty tools runs efficiently without voltage declines.

Industrial structures like shopping centers, offices, and medical facilities also utilize these transformers. They distribute dependable power for illumination, heating, cooling systems, computers, and various other crucial solutions. The pole-mounted layout is practical in metropolitan locations where ground space is limited.

These transformers are important for rural electrification tasks. They bring usable power from long-distance high-voltage lines directly to towns and farms. Smaller communities gain from the trusted 400V supply for homes, small companies, and farming tools.

The 400kVA and 500kVA versions prevail for supplying power to groups of houses or small industrial clusters. The 4000kVA unit serves huge real estate growths or dense business districts needing substantial capability. Post mounting simplifies installment near the factor of use.

Utilities release these transformers extensively across their networks. They form the essential web link between the high-voltage transmission grid and the lower-voltage circulation lines feeding end customers. Their durable layout withstands outside weather conditions dependably. They are constructed for lengthy life span with minimal maintenance.
