Three-Phase Oil Type Transformer S9, S11

Reliable Structure

Based on the traditional structure and mature technology, our company has made many improvements, such as:
1) Spiral coil with longitudinal oil passage, better internal heat dissipation;
2) Improved the effective support of the coil end surface, and the ability to resist short-circuit current is stronger;
3) The new hoisting structure and body positioning structure are adopted to ensure more reliable in long-distance transportation and operation;
4) We have many unique and reliable structures to serve you;
5) Selecting a transformer with a higher performance level will have a higher level of technical content.

Excellent Materials

1) Oxygen-free copper wire with lower resistivity is selected, and after a series of additional surface treatments, it is smoother and free of burrs and sharp corners, making the load loss of the transformer lower and the electrical performance more reliable.
2) Select high-quality silicon steel sheets. With the improvement of performance level, use silicon steel sheets with lower unit loss to make the transformer no-load loss lower.
3) Select high-quality laminated wood insulation parts, never crack, even under the action of short-circuit current, the wire will not move.
4) Transformer oil after deep filtration is selected. The lower water, gas and impurity levels make the transformer work more reliable.
5) Select high-quality rubber sealing materials to effectively prevent aging and prevent leakage.
6)  All raw materials have passed the quality inspection, and all raw material manufacturers have undergone strict review in accordance with the national standard ISO9000.

Product Features

• Voltage Conversion and Transmission: The S9 series transformer can convert high voltage into low voltage or increase low voltage to meet the voltage requirements of different power equipment, achieving stable transmission of electrical energy.
• Energy saving and loss reduction: Compared with the previous S7 series, the S9 series transformers have reduced no-load and load losses, with significant energy-saving effects, which helps to reduce the operating costs of the power system.
• High reliability: Adopting a highly reliable structural design improves the operational reliability of the product and reduces power outages caused by transformer failures.
• Strong environmental adaptability: The S9 series transformer can operate stably under various environmental conditions, including high temperature, low temperature, humidity and other harsh environments, adapting to a wide range of load requirements.
• Easy maintenance: Adopting a fully sealed structure reduces maintenance workload and extends the service life of the transformer.
