Since the reform and opening up, the country's economic development has developed rapidly, and exchanges between various places have become increasingly frequent. Therefore, my country's transportation construction industry has to develop rapidly. Our country's large territory, vast territory, and complex terrain have brought many difficulties to transportation construction. But it is precisely because of this that traffic construction is more important and necessary, especially tunnel construction under adverse geological and complex environmental conditions.
In the past ten years of transportation construction, the transportation network has been continuously improved, and the construction of highways and railways has gradually extended to the mountainous areas. In roads and railways, the proportion of tunnels is getting higher and higher. Therefore, in transportation construction, the construction scale of both mountain-crossing tunnels and deep-water submarine tunnels is getting bigger and bigger! Compared with other transportation construction, tunnel construction Construction work is the most difficult and riskiest.
In the construction of many large-scale and long-distance tunnels, the voltage drop caused by the long-distance power supply is too large, and the machine cannot operate normally. Therefore, our company specially developed a special automatic step-up transformer for tunnels to solve this problem. It truly solves the problem that electrical equipment cannot operate normally due to problems such as long power supply distance, low terminal voltage, and large voltage fluctuation range during tunnel construction. Since the transformer was put into the market, it has been well received by users such as mining enterprises and tunnel construction units. It can be said that the development and use of this automatic step-up transformer for tunnels has provided great convenience for mine development and tunnel construction.
