Description

The 10kV oil immersed distribution transformer is engineered for high efficiency, durability, and reliable medium-voltage power supply. With a fully sealed corrugated oil tank, it prevents oil contact with air, reducing oxidation and extending insulation life. This sealed design ensures moisture resistance, low maintenance, and safe long-term performance. Compact and robust, it is ideal for urban substations, renewable energy integration, and industrial applications requiring stable, high-quality power.

Applications

• Commercial and residential power distribution - reliable electricity supply for buildings, schools, and universities

• Hospitals and medical centers - ensuring safe and stable power for critical facilities

• Industrial plants and factories - durable design for demanding environments

• Airports, subways, and data centers - compact footprint with high reliability

• Renewable energy projects - suitable for wind, solar, and distributed generation systems

Advantages

• Long Service Life: Fully sealed oil tank prevents contact with air, reducing oil oxidation and insulation aging.

• High Reliability: Advanced sealing technology and robust construction ensure stable and safe operation.

• Moisture Resistance: Sealed design prevents moisture absorption, maintaining insulation strength and performance.

• Efficient Cooling: Corrugated tank design functions as a built-in radiator, eliminating the need for a separate oil storage tank.

• Compact and Space-Saving: Small footprint and aesthetic design make installation flexible and convenient.

• Low Maintenance: Sealed design and durable materials reduce maintenance requirements.

• Structural Integrity: Tank and edges can be bolted or welded, ensuring long-term durability.

• Versatile Applications: Suitable for urban, industrial, commercial, and renewable energy power distribution systems.
