In tunnel construction, a stable power supply is the key to ensuring the safety and efficiency of construction, and oil-immersed voltage regulators play an irreplaceable role in this regard.
Solving Voltage Problems
The tunnel construction environment is complex, often facing issues such as long distances from substations and long cable installations. As a result, the input voltage is often lower than the normal operating voltage. Commonly, the voltage drops to 320V - 340V, while construction equipment usually requires a voltage of 380V - 420V to operate normally. The oil-immersed voltage regulator can precisely adjust the input voltage, boosting and stabilizing the unstable low voltage to the required voltage range, meeting the power needs of various electrical equipment in tunnel construction, such as ventilation equipment, excavation equipment, and lighting equipment.
