9.Altiude is not exceeding 1000m,ambient temperature not exceeding 40OC. If it can't meet such conditions,we will modulate parameters in accordance with standard.
- Oxygen-free copper lines of lower resistivity, which will become smoother and burr-free after series of additional surface treatment, so the load loss of our transformer is lower and the electric performance is better.
- High-quality silicon-steel plates which are of lower unit loss, and the no-load of the transformers is lower.
- High-quality wooden laminating insulation pieces, which won't split or move even under the influence of short circuit.
- Thoroughly filtrated transformer oil containing less water, gas and impurities, which makes our transformers work better.
- High-quality rubber sealing material, which can prevent the transformers form aging or leakage.
