The features of three-phase oil-immersed distribution transformer

ZTELEC produce three-phase oil-immersed distribution transformer produced that adopts a new insulation structure to improve the short-circuit resistance. The iron core is made of high-quality cold-rolled silicon steel sheet; the high-voltage winding is made of high-quality oxygen-free copper wire as the material And adopt multi-layer cylindrical structure. All sturdy parts adopt special anti-loosening treatment.

Three-phase oil-immersed distribution transformer has the characteristics of high efficiency and low loss which can save a lot of power consumption and operating costs, and has significant social benefits. It is a high-tech product promoted by the country.

The reliable structure of three-phase oil-immersed distribution transformer

Based on the traditional structure and mature technology, our company has made many improvements as following:

1. Spiral coil with longitudinal oil passage, better internal heat dissipation.

2. The effective support of the coil end surface is improved that has the ability to resist short-circuit current is stronger.

3. A new hoisting structure and body positioning structure of three-phase oil-immersed distribution transformer are adopted to ensure more reliability in long-distance transportation and operation.

4. We also 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.

High-quality materials of three-phase oil-immersed distribution transformer

Oxygen-free copper wire with lower resistivity is selected and after a series of additional surface treatments,three-phase oil-immersed distribution transformer is smoother and free of burrs and sharp corners to make the load loss of the transformer lower and the electrical performance more reliable.

We choose high-quality silicon steel sheet of three-phase oil-immersed distribution transformer. With the improvement of performance level, use silicon steel sheet with lower unit loss to make the transformer no-load loss lower.

Select high-quality laminated wood insulation of three-phase oil-immersed distribution transformer, never crack, even under the action of short-circuit current, the wire will not move.

Transformer oil after deep filtration is selected. The lower water, gas and impurity levels make the transformer work more reliable.

Choose high-quality rubber sealing materials to effectively prevent aging and prevent leakage.

Quality inspection of all raw materials effectively prevents aging and prevents leakage.

The advantages of three-phase oil-immersed distribution transformer

Selecting M in S11 (M) R means that the oil tank adopts a fully sealed structure. Compared with the ordinary oil-immersed transformer, the fully sealed distribution transformer eliminates the oil storage tank. The wave fin of the three-phase oil-immersed distribution transformer oil tank replaces the oil pipe as a cooling and cooling element and the corrugated oil tank is made of high-quality cold-rolled sheet on a dedicated production line that the wave fins can increase and decrease the volume of the transformer oil, thereby isolating the transformer from the atmosphere, preventing and slowing oil degradation and insulation moisture, enhancing operational reliability, and maintaining normal operation without maintenance.

The surface of the corrugated oil tank is coated with tri-proof paint after degreasing, derusting and phosphating treatment, which is suitable for use in metallurgy, petrochemical, mining and other environments.
