1250KVA 15/0.4KV Outdoor Compact Transformer Substation Ordinary Oil Immersed Transformer

Overview of 1250KVA 15/0.4KV Outdoor Compact Transformer Substation Ordinary Oil Immersed 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 1250KVA 15/0.4KV Outdoor Compact Transformer Substation Ordinary Oil Immersed 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.

5 FAQs of 1250KVA 15/0.4KV Outdoor Compact Transformer Substation Ordinary Oil Immersed Transformer

What capacity does this substation handle?
This unit handles 1250 kilovolt-amperes. It powers medium-sized factories, shopping centers, or housing complexes. It manages significant electrical loads reliably.

What voltages does it convert?
It steps down high voltage electricity. Input is 15,000 volts from the main grid. Output is 400 volts for local buildings and equipment. This makes power usable for standard machinery.

Is it built for outdoor use?
Yes. The entire substation is designed for outdoor installation. It withstands rain, wind, dust, and sun exposure. The transformer and switchgear are inside a tough, weatherproof steel enclosure. This protects the electrical parts.

Why use an oil-filled transformer?
Oil cools the transformer windings effectively. It prevents overheating during heavy use. The oil also provides electrical insulation inside the tank. This design is proven, reliable, and cost-efficient for this power level.
