Why is the primary voltage level of rectifier transformers generally 35 KV?

For the 35KV voltage level, I believe it is commonly used in industrial and mining enterprises. The power consumption for rectification and electrolysis in the chlor-alkali industry constitutes a significant portion of the total energy consumption. Of course, a higher voltage level results in lower losses; however, taking into account factors such as the safety, maturity, and practicality of equipment manufacturing, as well as comprehensive investment efficiency analysis, the 35KV voltage level is generally chosen. Rectifier transformers with voltage levels above 35 KV also exist, but they are less common. Some companies use a step-down transformer with 110 KV voltage. When selecting the voltage level, it is also necessary to communicate appropriately with the local power grid management.
Thank you! Is it related to reactive power compensation? If there is sufficient reactive power available, 110 KV is used; otherwise, 35 KV is used, as it is easier to provide compensation in that case
In fact, 110 KV is preferred these days, as it not only reduces equipment investment but also lowers operating costs. Most chlor-alkali plants abroad use 110KV.
That’s right; the voltage level is determined by the conditions of the local power grid. There are no specific requirements as to whether 35KV or 110KV should be used, right?
The selection of voltage level is primarily determined by the local power grid conditions, while also taking into account the enterprise’s electricity consumption load. After all, the higher the voltage level, the greater the investment required by enterprises. When selecting the voltage level, the operating cost savings resulting from raising the voltage level should be compared with the investment required. At the same time, the increased maintenance costs in the future should also be taken into account.
