Whole Customized Oil Filled Transformer 7000 Kva 33kv Power Transformer High Voltage Oil Immersed Distribution Transformer

Overview of Whole Customized Oil Filled Transformer 7000 Kva 33kv Power Transformer High Voltage Oil Immersed 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 Whole Customized Oil Filled Transformer 7000 Kva 33kv Power Transformer High Voltage Oil Immersed 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.

5 FAQs of Whole Customized Oil Filled Transformer 7000 Kva 33kv Power Transformer High Voltage Oil Immersed Distribution Transformer

What customization options exist for this transformer?
You choose specific requirements. We adapt winding materials, cooling systems, voltage taps. Tell us your exact needs. We build the transformer to match them perfectly.

How does the oil cooling system work?
Mineral oil surrounds the core and windings inside the tank. The oil absorbs heat during operation. This heat moves to the tank walls. Radiators or cooling fins attached to the tank release the heat into the air. This keeps the transformer at safe temperatures.

What safety features protect this transformer?
The design includes a pressure relief device. This vents excess pressure inside the tank safely. A Buchholz relay detects gas buildup from internal faults. It triggers an alarm or shutdown. An oil level gauge shows if oil is low. These features prevent major failures.

How efficient is this 7000kVA transformer?
Efficiency is high. We minimize energy wasted as heat. Core steel quality and optimized design reduce losses. Lower losses mean less operating cost over the transformer’s life. You save money on electricity.

How long does delivery take after ordering?
Delivery time depends on customization complexity. Standard designs ship faster. Highly customized units take longer for engineering and manufacturing. Expect several weeks to a few months. We provide a firm timeline after reviewing your specifications.
