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

Overview of Energy Saving Oil Immersed 1250KVA Transformer 15/0.4KV Outdoor Compact Substation

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

• 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 Energy Saving Oil Immersed 1250KVA Transformer 15/0.4KV Outdoor Compact Substation

Customers often ask about our Energy Saving Oil Immersed 1250KVA Transformer Substation (15/0.4kV). Here are the top five questions:

What makes this transformer save energy?
The transformer core uses high-grade, low-loss silicon steel. This special steel reduces wasted energy significantly. Less energy lost as heat means lower electricity bills. You save power over the transformer’s entire life.

Is the oil inside safe?
Yes. The transformer uses a special mineral oil. This oil is very stable. It also acts as a coolant and insulator. The tank holding the oil is completely sealed. This prevents leaks. The oil won’t catch fire easily. It meets strict safety standards.

Where can we install this substation?
This compact substation is built for outdoor use. It handles tough weather. Place it on a strong, level concrete pad. The pad must support the full weight. Ensure good airflow around the unit. Keep it away from walls or fences. This allows heat to escape properly.

How much maintenance does it need?
These transformers need very little maintenance. The sealed tank protects the oil. Check oil levels and connections yearly. Look for leaks or damage. Clean the outside surfaces occasionally. This basic upkeep keeps it running reliably for years. Major service is rare.
