Industry-Leading Oil-Immersed Transformer Manufacturer — Engineered for Efficiency & Durability

Scientific structural

Based on a traditional structural design and mature manufacturing technology, oil immersed transformer  from leading oil immersed transformer manufacturers like Tenrony have undergone numerous improvements and offer the following advantages:

1. The spiral winding with longitudinal air ducts provides enhanced internal heat dissipation performance.

2. Improved effective support at the coil end face increases the oil immersed transformer's ability to withstand short-circuit currents.

3. A new lifting structure and body positioning system have been adopted, ensuring greater reliability during long-distance transportation and operation.

4. The implementation of a unique and reliable structural design contributes to more stable product performance.

5. High-quality silicon steel sheets with superior magnetic properties are used in the core, resulting in improved energy efficiency, reduced noise levels, and an overall higher technical standard.

6. The oil immersed distribution transformer employs a cast structure, while the internal air channels utilize a prismatic configuration. This design expands the heat dissipation space, accelerates air circulation, prevents and delays insulation degradation and moisture absorption, thereby enhancing operational reliability and enabling maintenance-free normal operation.

High-Quality Material

All raw materials used in oil immersed transformers undergo rigorous inspection, and all material suppliers are strictly evaluated in accordance with the ISO 9000 international quality management standard.

1. Oxygen-free copper wire with lower resistivity is selected. After a series of advanced surface treatments, the wire surface becomes smoother and free of burrs or sharp edges, thereby reducing oil immersed transformer load losses and enhancing electrical performance reliability.

2. With the improvement of performance levels, silicon steel sheets with lower unit losses are employed, resulting in reduced no-load losses of the immersed transformer.

3. High-quality laminated wood insulation components are selected, which remain crack-free and stable even under the mechanical stress of short-circuit currents.

4. The use of premium insulation materials ensures superior insulation performance, enhanced product quality and reliability, and improved operational stability of the oil immersed distribution transformer.

5. High-performance rubber sealing materials are selected to provide effective resistance against aging.

Equipment Durability

All components of the oil immersed transformer are certified products that comply with the inspection and testing requirements set by relevant national regulatory bodies. These oil immersed distribution transformer components are designed to operate without causing adverse effects and are environmentally safe.
