Features

The three-phase oil-immersed distribution transformer produced by our company adopts a new type of insulation structure to improve the short-circuit resistance; the iron core is made of high-quality cold-rolled silicon steel sheet; the high-voltage windings are all made of high-quality oxygen-free copper wire. , And adopts multi-layer cylindrical structure; all solid parts adopt special anti-loosening treatment.

Reliable structure

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

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

2. Improved the effective support of the coil end face, and the ability to withstand short-circuit current is stronger;

3. The new hoisting structure and positioning structure of the body are adopted to ensure more reliable in long-distance transportation and operation;

4. We also have many unique and reliable structures to serve you;

5. Choosing a transformer with a higher performance level will have a higher level of technical content.

Quality materials

The oxygen-free copper wire with lower resistivity is selected, and after a series of additional surface treatments, it is smoother and has no burr sharp corners, so that the load loss of the transformer is lower and the electrical performance is more reliable.

Choose high-quality silicon steel sheets, and with the improvement of performance level, use silicon steel sheets with lower unit loss to make the transformer no-load loss lower.

Use high-quality laminated wood insulation, which will never crack, even under the action of short-circuit current, it will not move.

Choose transformer oil that has been deeply filtered, with lower water, gas, and impurity levels, and the transformer will work more reliably.

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

All raw materials undergo quality inspection to effectively prevent aging and prevent leakage.

All raw materials undergo quality inspection, and all raw material manufacturers have undergone strict inspections in accordance with the national standard ISO9000.
